F15/F30 Ball Valves

DESIGN

The design features of this valve include a split body, two piece construction, allowing ease of maintenance without special tools. These valves feature a “free ﬂoating” ball. The ball is not ﬁxed, but is free to move with the line pressure.

As a result of this feature, these valves are capable of tight shut-off with ﬂow in either direction or dead-ended, regardless of the position of the valve in the line.

The downstream seat, opposite the pressurized side of a closed valve, must carry the load exerted by the line pressure on the ball, while the upstream seat is subject to little load or wear. For this reason, it is sometimes possible to increase useful seat life by turning the valve end-for-end in the pipeline.

1. USE:

The valve should be maintained as part of a preventative maintenance program and in accordance with Flow-Tek’s recommended pressure, temperature and corrosion limits to insure a long service life. During shipment, storage, and in operation, the valve should be fully open or fully closed (“open” is preferred for shipping and storage). Do not use in throttling service without investigating ﬂow and pressure conditions.

WARNING: Before installing this equipment, conﬁrm that it is suitable for the intended service.

B. VALVE IN CLOSED POSITION

The handle is perpendicular to the pipeline.

Valves with actuators should be checked for actuator -valve alignment. Misalignment will result in high operational torque and damage to valve stem and seals.

3. STEM SEAL ADJUSTMENT

1. For 1/2”- 2”, if slight leakage is noted at stem, straighten lock washer tab, tighten stem nut to ﬂatten Bellville Washers, back stem nut off 1/4 turn, secure lock washer tab.

2. For sizes larger than 2”, simply tighten gland bolts evenly until leak stops. Do not over tighten.

4. GENERAL INFORMATION FOR ON-SITE INSTALLATION:

The valve may be ﬁtted in any position on the pipeline.

Before installing the valves, the pipes must be ﬂushed clean of dirt, burrs, and welding residues, or the seats and ball surface will be damaged.

5. DISASSEMBLY AND CLEANING PROCEDURE:

CAUTION: Line must be depressurized before disassembly. Valve should be cycled to assure there is no pressure is trapped in valve cavity. Ball valves can trap pressurized media when closed. Flush line with valve 1/2 open to remove hazardous media.

The identiﬁcations tags describe the maximum allowable service conditions for this product.

Be sure that the installation is protected by appropriate pressure control and safety devices to insure that acceptable limits are not exceeded.

2. OPERATION:

Operation of the valve is done by turning the handle a 1/4 turn (90 degree turn). CW to close, CCW to open.

A. VALVE OPEN POSITlON

The handle is parallel with the pipeline.

WARNING: DO NOT remove packing gland or any other valve parts while line is under pressure!

Stem seal leakage may be corrected without disassembly by tightening the packing gland nut until such leakage stops. If the leakage continues or valve operating torque becomes excessive, the seals are worn and replacement will be necessary.

If the valve has been used to control hazardous media, it must be decontaminated before disassembly.

It is recommended that the following steps be taken for safe removal and assembly.

As shipped from the factory, Valves contain Silicone based lubricant. This is for break-in and may be removed by disassembly and solvent washing, if it is objectionable for a particular application,

6. DISASSEMBLY FOR STEM AND SEAL REMOVAL:

1. Remove ﬂange bolts and nuts and lift valve from line for servicing.

NOTE: Care should be taken to avoid scratching or damaging serrated ﬂange face. These valves

are heavy!

They should be adequately supported before removal from the line is begun.

2. Loosen handle set screw and remove handle and stop plate. Next, remove gland nuts, gland ﬂange and gland.

3. Remove body end nuts, using proper wrench size. Lift off body end. One seat should come out with body end.

4. Remove body seal.

5. To take out the ball, rotate stem so ball is in fully closed position. Lift ball from body, using a strap and lift device, if necessary. NOTE: Extreme caution should be taken to avoid damage to the ball.

6. Take out other seat.

7. Stem must be removed from inside the body - a tap on the top of the stem should loosen it. The thrust washer should come out with the stem. Then remove the stem packing.

7. VISUAL INSPECTION:

dry where no lubricants are allowed in the system; however, a light

lubrication of mating parts will aid in assembly and reduce initial operating torque. Lubricant used must be compatible with the intended line ﬂuid.

8. ASSEMBLY:

1. Install one seat in the body seat cavity with the spherical curvature facing the ball.

2. Install thrust washer on stem and slide the stem up through the body. Install packing and packing gland with packing gland bolt.

3. Install stop plate, handle and handle retainer nut.

4. Turn the handle CW to the CLOSED position. Line up the ball slot with the stem tang and slide the ball into position. Turn the handle CCW to the OPEN position to hold the ball in place.

5. Install the remaining seat into end cap seat pocket

6. Put body seal gasket into shoulder counter bore at ﬂange in valve body.

7. Put end cap back into body and line up end ﬂange. Because the body ﬂange bolt pattern is different from the line ﬂange bolt pattern, it is possible to assemble the valve which the bolt holes in the line ﬂanges don’t line up. Be certain to align end ﬂanges bolt holes to straddle valve center lines.

NOTE: Be careful not to damage body seal when assembling end into body.

8. Install body end nuts and tighten in a crossing pattern to the torque speciﬁed in Table 1.

Clean and inspect metal parts. It is not necessary to replace the hall and stem unless the seating surfaces have been damaged by abrasion or corrosion. we strongly recommend replacement of all soft parts whenever the valve is disassembled for reconditioning.

This is the surest protection against subsequent leakage after valve assembly. The replacement parts can he ordered in kit form.

NOTE: The valve may be assembled and operated

9. WARNING: Extreme care must be exercised during adjustment of body stud nuts to make sure that body studs are fully engaged. There should be at least one stud thread exposed beyond the ﬂange on the body side and beyond the nut on the cap side.

10. Cycle the valve slowly, with a gentle back and forth motion, to build gradually to the full quarter turn. By cycling slowly, the seat lips will assume a permanent seal shape against the ball. A fast turning motion, at this point, may cut the seats before they have a chance to form the proper seal.

11. Test valve, if possible, prior to placing valve hack into line position. WARNING: If not properly secured,

the valve can separate from the pressure source, resulting in possible injury. Always join the valve to companion.

12. ﬂanges of same pressure rating as valve and secure with a full set of ﬂange bolts.

pour the water out, cycle the valve several times and recheck. To check for leakage in the other port, reverse the valve and introduce air pressure to the port just checked.

3. Check stem seal at this time by coating the gland area with a soapy water solution. If leakage occurs, tighten stem seal just until leakage stops.

TEST AS FOLLOWS

1. Secure valve to a test future by means of a mating ﬂange with full bolting and a suitable gasket. Orient valve so seat to he tested is facing up.

2. Introduce 50 to 100 psig air. Partially cycle the valve, under pressure, and then slowly close to make sure the cavity is pressurized (use hearing protection). Pour water into the upper port to cover the ball and visually check for bubbles. If bubbles appear,
