Valtek Mark 200 High Pressure Control Valve

The Mark 200 high pressure globe control valve designed to handle the most extreme severe service applications also offers high competitive ﬂ ow capacity. The Mark 200’s large galleries include longer stroke lengths which provide ﬁ ner control and result in more stages of severe service protection in smaller size valves. With a clamped-in (DIN, screwed-in) seat ring, the Mark 200 has been designed for easy maintenance and ﬂ exibility. The seat retainer/cage (DIN, seat ring) in the Mark 200 can be changed out to provide an exceptional variety of severe service options, including anti-cavitation and anti-noise.

Further sizing details are available in Performance!, Flowserve’s control valve sizing & selection software program (please contact your local Flowserve representative for further details). The plug is typically pressure-balanced to allow smaller and more economical actuators. Flow over or under the plug is available.

1 General Information

The following instructions are designed to assist in unpacking, installing and performing maintenance as required on Flowserve Mark 200 control valves. Product users and maintenance personnel should thoroughly review this bulletin prior to installing, operating or performing any maintenance on the valve. Separate Installation, Operation, and Maintenance instructions cover additional features (such as special trim, actuators, handwheels, packing and positioners.)

To avoid possible injury to personnel or damage to valve parts, WARNING and CAUTION notes must be strictly followed. Modifying this product, substituting non-factory parts or using maintenance procedures other than outlined could drastically affect performance and be hazardous to personnel and equipment and may void existing warranties.

WARNING: Standard industry safety practices must be adhered

to when working on this or any other process control product. Speciﬁcally, personal protective and lifting devices must be used as warranted.

NOTE ON FASTENERS: Selecting the proper fastener material is the

responsibility of the customer. Typically, the supplier does not know what the valve service conditions or environment may be. Flowserve’s standard body bolting material is B7/2H. B8 (stainless steel) is optional for applications more than 800°F / 425°C and with stainless steel or alloy-body valves. The customer therefore must consider the material’s resistance to stress corrosion cracking in addition to general corrosion. As with any mechanical equipment, periodic inspection and maintenance is required. For more information about fastener materials, contact your Flowserve representative.

2 Terms Concerning Safety

The safety terms DANGER, WARNING, CAUTION and NOTE are used in these instructions to highlight particular dangers and/or to provide additional information on aspects that may not be readily apparent.

DANGER: indicates that death, severe personal injury and/or

substantial property damage will occur if proper precautions are not taken.

WARNING: indicates that death, severe personal injury and/ or substantial property damage can occur if proper precautions are not taken.

CAUTION: indicates that minor personal injury and/or property damage can occur if proper precautions are not taken.

NOTE: indicates and provides additional technical information,

which may not be very obvious even to qualiﬁed personnel. Compliance with other, not particularly emphasized notes, with regard to transport, assembly, operation and maintenance and with regard to technical documentation (e.g., in the operating instructions, product documentation or on the product itself) is essential, in order to avoid faults, which in themselves might directly or indirectly cause severe personal injury or property damage.

4.1 ASME Valve Quick-check

Prior to start-up, check the control valve by following these steps:

WARNING: Due to the risk of injury, it is prohibited to work between the yoke/columns while the valve is in operation.

1. Stroke the valve and observe the plug position indicator on the stem clamp compared to the stroke indicator plate. The plug should change position in a smooth, linear fashion.

NOTE: Due to excessive friction, graphite packing can cause the plug stem to move in a jerky fashion.

2. Check for full stroke by making appropriate instrument signal change.

3. Be sure to provide proper overhead clearance for the actuator to allow for disassembly of the plug from the valve body. Refer to Table 1 for the necessary clearance needed for valve disassembly.

4. Double-check ﬂow direction to be sure the valve is installed correctly. Flow direction is indicated by the arrow attached to the body.

5. If welding the valve into the line, use extreme care to avoid excess heat buildup in the valve.

6. Connect the air supply and instrument signal lines. Throttling control valves are equipped with a valve positioner. Refer to the appropriate

positioner bulletin for connections, maximum air supplies, and maintenance instructions.*

CAUTION: On valves equipped with air ﬁlters, the air ﬁlter must point down to perform properly. *

3. Check all air connections for leaks.*

4. Check packing box bolting for the correct adjustment. Refer to the packing installation manual for speciﬁc details on maintaining the style of packing supplied.

CAUTION: Do not overtighten packing. This can cause excessive packing wear and high stem friction that may impede plug movement.

5. Make sure the valve fails in the correct direction in case of air failure. This is done by turning off the air supply and observing the failure direction.**

6. After a temperature excursion has occurred, bonnet ﬂange bolting should be retorqued to ensure bonnet gaskets do not leak. See Table 2.

5 ASME Valve Maintenance

At least once every six months, check for proper operation by following the preventative maintenance steps outlined below. These steps can be performed while the valve is in-line and, in some cases, without interrupting service. If an internal problem is suspected, refer to the “Valve Disassembly and Reassembly” section.

WARNING: Keep hands, hair and clothing away from all moving parts when operating the valve. Failure to do so can cause serious injury.

8. Make sure positioner linkage and stem clamp or coupling pieces are securely fastened. If the stem clamp or coupling pieces are loose, check plug thread engagement (refer to the “Reassembling the Body” section for the correct procedure on aligning the plug with the seat.) Tighten stem clamp nut or counter nut.

9. Ensure all accessories, brackets and bolting are securely fastened.

10. If possible, remove air supply and observe actuator for correct fail-safe action.*

11. Check rubber actuator bellows for splits, cuts or wear.*

12. Check tightness of the actuator. Spray a soap solution around the cylinder actuator retaining ring, adjusting screw and actuator stem guide to check for air leaks through the O-rings. *

13. Clean any dirt and other foreign material from the plug stem.

14. If an air ﬁlter is supplied, check and replace cartridge if necessary.*

* Pneumatic operated control valves

** Pneumatic operated control valves with safety function

1. Look for signs of gasket leakage through the end ﬂanges and bonnet. Retorque ﬂange and bonnet bolting (if required). See Table 2.

2. Check for ﬂuid leakage to the atmosphere through the body drain plug, if applicable.

3. Examine the valve for damage caused by corrosive fumes or process drippings.

4. Clean valve and repaint areas of severe oxidation.

5. Check packing box bolting for proper tightness. Refer to the packing installation manual for speciﬁc details on maintaining the style of packing supplied.

CAUTION: Do not overtighten packing. This can cause excessive packing wear and high stem friction that may impede stem movement.

6. If the valve is supplied with a lubricator ﬁtting, check lubricant supply

and add lubricant if necessary. See product documentation or contact the Flowserve representative.

7. If possible, stroke the valve and check for smooth, full-stroke operation.

Unsteady stem movement could indicate an internal valve problem.

NOTE: Due to excessive friction, graphite packing can cause the plug stem to move in a jerky fashion.

ASME Disassembly and Reassembly

6.1 Disassembling the Body

To disassemble the valve body, refer to Figure 3 or 4 then proceed as follows:

WARNING: Depressurize line to atmospheric pressure and drain all ﬂ uids before working on the valve. Failure to do so can cause serious injury.

1. Fully retract the plug until the stem clamp indicator points to the open position.

2. Remove the bonnet ﬂ ange bolting and lift the actuator, bonnet and plug out of the valve body.

WARNING: Danger exists in removing the actuator, bonnet and

plug, especially if PTFE plug seals are used. The sleeve may stick to the plug and fall during disassembly, causing possible serious injury and damage to the valve or nearby equipment. If sleeve is observed sticking to the plug, steps 3–5 should be consulted.

Figure 4 – ASME Mark 200 Cutaway Drawing

CAUTION: If a rubber bellows is attached to the gland ﬂ ange, the gland ﬂ ange must be removed prior to removing the actuator.

CAUTION: Heavy actuators may require a hoist. Lift the actuator with the yoke legs using a lifting strap and a hoist. Great care should be taken to lift the actuator and plug straight out of the body to avoid damage to the plug and seat.

3. If the sleeve is observed sticking to the plug during removal, fully extend the plug by applying air above the piston, allowing the sleeve to remain in the body and the bonnet to rise above the body.

4. In the gap between the top of the sleeve and the bottom of the bonnet, place wooden blocking of equal thickness in at least three places. The wooden blocks must not extend in far enough that they interfere with plug movement. The plug must be allowed to stroke up to the bonnet.

5. By applying air below the piston, retract the plug until the plug head is freed from the sleeve. Once the plug is free from the sleeve, remove the plug and bonnet assembly from the body.

6. Lift the sleeve out of the valve body using lifting points on the top of the sleeve.

7. Remove cage, seat ring and gaskets from the valve body.

8. Remove the plug seals from the plug head.

9. Check to see the seating surfaces on both the seat ring and plug are free of damage to ensure tight shutoff. Make sure the gasket surfaces on the seat ring, bonnet and body are clean and undamaged. Inspect the pressure balanced sleeve for scratches or other damage.

11. Turn the actuator off the plug and bonnet without allowing the plug to rotate within the bonnet. Pull the plug carefully through the packing box. Inspect the plug stem for damage or scoring.

NOTE: With air-to-close, fail-open valves, it may be necessary to apply a small amount of air to the top of the actuator to move the plug away from the bonnet. Otherwise, plug galling may occur.

CAUTION: To avoid scoring guides and plug stem, follow the above procedure exactly.

12. If the seat surfaces need remachining, both surfaces on plug and seat ring must be reworked. The seat angle on the plug is 36 degrees and the seat ring is 33 degrees. Lapping is not necessary if proper assembly procedures are followed.

CAUTION: If remachining, protect the stem while turning. Ensure concentricity of the seat surface with the plug stem (or outside diameter of the seat ring, if machining the seat).

13. To replace packing or change the packing box conﬁ guration, push out packing, spacer and guides with a dowel slightly larger than the plug stem from underneath the bonnet.

10. Loosen the stem clamp and gland ﬂ ange. Remove the yoke bolts.

Mark 200 Control Valve FCD VLENIM0200– 12/12

6.2 Reassembling the Body

To reassemble the valve body, refer to Figure 3 or 4 then proceed as follows:

1. Install new bonnet and seat gaskets with the beveled edge up on ﬂuoropolymer gaskets.

NOTE: All gaskets should be replaced whenever the valve is disassembled.

2. Relocate the seat ring. Carefully install the cage and then the sleeve with the indexing feature provided, taking care to ensure they install with the correct ends up.

3. Replace the plug seals on the plug, referring to Figure 5 and 6, and observing the following directions:

WARNING: Gloves should be worn to help prevent the hands from being pinched or burned.

PTFE Seals Heat one seal to 300°F (150°C) and slip it over the plug into the

seal groove. Thermal expansion causes the ring to stretch, thereby making it relatively easy to slide over the plug head.

Care must be taken to prevent the seal from rolling, rather than sliding over the plug. The second seal can be installed following the same procedures as the ﬁrst. If for any reason the second seal cannot be slipped onto the plug, cut the seal at approximately a 30° angle (see Figure 6) and place over the plug. Make certain the cut seal is on the low-pressure side.

Figure 5 – Seal Designs

O-ring Seals

Carbon Single Seal Carbon Triple Seal

Figure 6 – PTFE Seal Cutting Detail

PTFE Seals Metal Multi-Seal

Carbon Seals

Single Seals Each seal must be scored on a face with a sharp knife at

two places, 180 degrees apart. Holding the ring gently in a padded vise, pull gently on the ring, breaking the ring on the score marks into two equal pieces. Install the two pieces into the plug seal grooves with the score marks on the pressure side.

Triple Seals Gently insert one end of seal and wrap the seal into groove. Install the inside ring ﬁrst, followed by the two outside rings with joints offset 120 degrees on all three rings (see Figure 5).

CAUTION: Install rings starting with one end and working the ring carefully into place. Do not spread ring more than necessary. Spreading the ring too much can cause the ring to break.

Metal Multi-Seals Install wave spring followed by four seal rings. Stagger ring openings by at least 90 degrees. Take care not to bend the seal rings as they are installed.

O-ring with Back-up Rings The O-ring can stretch over plug and into place. Spread scarf cut back-up rings until they ﬁt on each side of O-ring as shown in Figure 5.

Mark 200 Control Valve FCD VLENIM0200– 12/12

4. Lower the plug into the body and sleeve. Care should be taken with the plug seals to avoid scoring or galling the sealing surface while ﬁtting them into the sleeve bore. With metal multi-seals and carbon triple seals, use a ring compressor on the rings. A suitably sized screw-type hose clamp will also serve to compress the rings for reassembly.

5. Install sleeve gasket by centering on sleeve.

6. Lower the bonnet onto the plug and body, taking great care to avoid scoring the plug stem.

7. Once the bonnet is resting squarely in the valve body, ﬁnger-tighten the bonnet ﬂange bolting.

8. Reinstall the packing and guides referring to the appropriate packing installation manual and reinstalling new packing exactly as shown. Make sure at least 1⁄8” (3 mm) is left at the top of packing box for the top guide to enter. Different spacer lengths permit a wide variety of packing conﬁgurations, such as twin seal and vacuum-pressure packing

WARNING: Valves with extended bonnets must not have lower packing installed. Instead, lower packing rings should be installed with the upper set. Lower packing installed in extended bonnets will diminish the integrity of the packing assembly.

NOTE: Graphite guide liners should be replaced each time the valve

packing is replaced. Do not rebuild the valve without new graphite liners in the guides.

13. Slowly stroke the plug up and down to check the alignment of the plug with the sleeve.

CAUTION: If binding or sticking is observed, discontinue stroking the valve and reassemble using the above steps. Failure to do so could cause serious valve damage. Contact your Flowserve representative if binding cannot be resolved.

14. Perform a Quick Check as described in section 4.1.

9. Replace and tighten the packing gland and bolting. Refer to the packing installation manual for speciﬁc details on maintaining the style of packing supplied. Make sure gland ﬂange is level after 3 nuts are tightened.

10. Turn actuator back onto the body assembly, without turning the plug inside the bonnet. Leave a 3⁄32” to 1⁄8” (2 mm to 3 mm) gap between the mating surfaces of the bonnet and yoke. Tighten yoke bolting to close this gap. Firmly tighten the yoke bolting.

11. Using the actuator, seat the plug two or three times to center the seat ring using pressure on the top of the actuator.

12. Tighten the body bolting, following the bolting sequence outlined in Figure 7. Use a minimum of four steps to reach the suggested bolt torque values shown in Table 2. Never exceed more than 30% of the suggested bolt torque value in a single step.

7 DIN Valve Unpacking

1. Careful loading and transport arrangements are required to avoid the product suffering impact and jolting movements. Under no circumstances should lifting gear be attached to the valve stem, travel indicator or any peripheral units, if applicable. We recommend the use of a length of rope that is looped around the valve head underneath the yoke. Promptly touch up any damage to the corrosion protection.

2. Upon arrival on site, store the control valve on a solid base in a closed room. Until its installation, the valve must be protected from the weather, dirt or other potentially harmful inﬂuences. Under no circumstances should the valve remain in storage for more than 6 months, as the impregnation in the stufﬁng box packing evaporates and leaks may develop. Do not remove the plugs protecting the ﬂanges and the inside of the control valve until it has arrived at its place of installation.

3. While unpacking the valve, check the packing list against materials received. Lists describing valve and accessories are in each shipping container.

WARNING: When lifting a valve using the rope, be aware that the

center of gravity may be above the lifting point. Therefore, support must be given to prevent the actuator from rotating. Failure to do so can cause serious injury to personnel, damage to the valve or nearby equipment.

4. Contact your shipper immediately if there is shipping damage.

5. Should any problem arise, call your Flowserve representative.

6. The export packaging follows the packaging guidlines according to the HPE stantards. The nonreturnable package is based on 90% recyclable materials (cardboard box, wooden pallet etc.).

8 DIN Valve Installation

1. Before installing the valve, clean the line of dirt, welding chips, scale or other foreign material.

CAUTION: Do not insulate extension bonnets that are provided for hot or cold services.
