Installation

WARNING

Always wear protective gloves, clothing, and eyewear when performing any installation operations to avoid personal injury.

To avoid personal injury or property damage resulting from the sudden release of pressure, do n ot install the valve assembly where service conditions could exceed the limits given on the valve and actuator nameplates. Use pressure-relieving devices as required by accepted industry, local, state, or federal codes, and good engineering practices.

Check with your process or safety engineer for any additional measures that must be taken to protect against process media.

If installing into an existing application, also refer to the WARNING at the beginning of the Maintenance section in this instruction manual.

WARNING

Avoid personal injury or property damage caused by uncontrolled movement or dropping of the valve assembly.

Hoist rings are sized to lift only the valve and actuator. Do not use hoist rings to lift the valve if piping or other structures are added.

Rig the lift to use two hoist rings and take appropriate precautions to avoid unbalanced loading which may result in sudden swinging or movement of the assembled unit, including additional lifting and/or support methods when necessary.

Failure to utilize safe lifting practices may result in equipment damage and/or personal injury.

removed for maintenance, mount the actuator according to the actuator mounting procedure and adjust actuator travel before inserting the valve into the pipeline. This allows necessary measurements to be made during the actuator adjustment process.

The actuator can be either right-or left-hand mounted, as viewed from the valve body inlet, in any of the positions shown in figure 10. Refer to the Actuator Mounting procedure in this manual and to the actuator instruction manual for mounting and adjusting instructions before proceeding.

6. Before installing the valve, make sure the flow through the valve matches the flow direction arrow on the valve. Failuretodosocandamagethesealinavalvewithasinglesealconstruction.

D For bidirectional flow, install the valve so the highest pressure flow matches the flow direction arrow on the valve.

D Install the V250 valve in any position, but the recommended orientation is in a horizontal pipeline with the shaft

positioned horizontally and the ball closing in the downward direction.

CAUTION

To avoid damage to the ball sealing surface, rotate the ball to the fully open position before installing the valve between thepipelineflanges.

7. With the ball in the fully open position, install line flange gaskets and insert the valve between the pipeline flanges. Use standard composition gaskets, or other flat sheet gaskets compatible with the flow media, between the valve and the pipeline flanges. Spiral wound gaskets without compression controlling centering rings are not recommended.

CAUTION

Uneven tightening of line bolts may cause uneven wear of the ball surface, leakage downstream or to atmosphere, or uneven flange gasket alignment. Tighten line bolts evenly when installing the valve.

8. Centerthevalveinthelinebymakingsurethematingflangesarealigned.Securethevalveinthelinewiththecap screws (keys 33 and 34, figures 11 and 12), line bolts (key 35, not shown), and hex nuts (key 44, not shown). Required clearances for installation of the line bolts and cap screws are shown in figure 2. When tightening the cap screws and line bolts, use accepted bolting procedures. Lubricate the studs or bolts and tighten the nuts in a crisscross sequence to ensure proper alignment of the valve with the flanges.

9. For hazardous atmosphere or oxygen service valves, read the following WARNING, and perform the instruction provided in the WARNING and provide the bonding strap assembly mentioned in Step 10 below if the valve is used in a hazardous application.

WARNING

The V250 is not necessarily grounded to the pipeline when installed. If the process fluid or the atmosphere around the valve is flammable, personal injury or property damage could result from an explosion caused by a discharge of static electricity from the valve components. If the valve is installed in a hazardous area, electrically bond the drive shaft to the valve.

Note

The packing is composed of all conductive packing rings (graphite ribbon packing) to electrically bond the shaft to the valve for hazardous area service or non-conductive PTFE packing rings. For oxygen service applications, perform the following step.

D100422X012

Maintenance

Valve parts are subject to normal wear and must be inspected and replaced as necessary. The frequency of inspection and replacement depends upon the severity of service conditions. Instructions are presented in this section for replacing the shaft seals, the ball seal or flow ring, the drive and follower shafts, the ball and bushing, and the valve outlet gasket.

Key number locations are shown in figure 11 for single seal and flow ring constructions, and in figure 12 for dual seal constructions.

WARNING

Personal injury or property damage can result due to a sudden release of pressure or process fluid if the pipe plug (key 42, figure 12) is removed while the valve is pressurized. To avoid such injury or damage, remove the pipe plug only when the control valve is isolated from the pressure system, or provide a hand valve to control relief of internal valve pressure to avoid personal injury or property damage.

A V250 valve with a dual seal construction contains a pipe plug port (key 42, figure 12) on the underside of the valve. This port can be used to relieve internal valve pressure for testing seal integrity when in the pipeline.

Ifthepipeplugportistobeusedfortestingsealintegritywhenthevalveisinthepipeline,theplugshouldbereplaced with a hand valve to allow controlled relief of valve pressure during seal leak rate testing.

WARNING

Avoid personal injury or damage to property from sudden release of pressure or uncontrolled process fluid. Before starting disassembly:

D Do not remove the actuator from the valve while the valve is still pressurized. D Always wear protective gloves, clothing, and eyewear when performing any maintenance operations to avoid personal

injury.

D Disconnect any operating lines providing air pressure, electric power, or a control signal to the actuator. Be sure the

actuator cannot suddenly open or close the valve.

D Use bypass valves or completely shut off the process to isolate the valve from process pressure. Relieve process pressure

on both sides of the valve. Drain the process media from either side of the valve.

D For dual seal valve constructions, remove pressure and drain the valve interior by removing the pipe plug

(key 42).

D Vent the power actuator loading pressure. D Use lock-out procedures to be sure that the above measures stay in effect while you work on the equipment. D The valve packing box may contain process fluids that are pressurized, even when the valve has been removed from the

pipeline. Process fluids may spray out under pressure when removing the packing hardware or packing rings, or when loosening the packing box pipe plug.

D Check with your process or safety engineer for any additional measures that must be taken to protect against process

media.

6. Once minimum clearance is obtained, temporarily remove the flow ring.

7. Insert the O-ring (key 13) into the valve, and secure the flow ring to the valve with the cap screws (key 15).

Installing Live-Loaded PTFE Packing

These steps refer only to the Live Loaded PTFE Packing. Key number locations are shown in figures 11, 12, and 13.

Note

The valve shaft's packing surfaces are critical in obtaining a good seal. If the valve shafts are scratched, nicked or worn, replace or repair the valve shaft beforeinstalling the Live Loaded PTFE Packing parts.

Both seal rings, drive end and follower end, should be replaced at the same time.

1. Remove the hex nuts (key 8) from the seal carrier (key 17 on the drive shaft end and key 3 on the follower shaft end). Remove the spacer (key 22). On NPS 4, 12, and 24 valves, the stud bolt (key 4) will need to be removed. The drive pin (key 28) needs to be removed from the outboard end of the valve body.

2. Replace the seal carrier and spacer with the new packing box (key 17 or 3). To keep the ball properly centered inside the valve body, the bushing spacer shims may need to be added or removed (see the Replacing Drive Shaft, Follower Shaft, Ball, Bushings, and Valve Outlet Gasket -- Assembly section).

3. Secure the packing box with hex nuts (key 8), for NPS 6, 8, 10, 16, or 20 valves, or socket head cap screw (key 4), for NPS 4, 12, or 24 valves. Lubricate the hex nuts or cap screws and tighten them. Be careful not to damage the O-ring during installation of the packing box.

4. Install the packing box studs (key 100).

Note

The Belleville springs must be stacked properly and packing box parts must be assembled in the correct order, if the packing parts are to function properly.

5. Install the packing ring, female and male adaptors, anti-extrusion rings, and packing box rings (keys 105, 106, and

107).Besuretoinstallthepackingringsintheorderandquantityshowninfigure13.

6. Install the spring pack assembly (key 103 or 104), which includes the Belleville springs, packing follower, and O-ring. The O-ring is a non-functional part used to retain the packing springs during assembly.

7. Install the packing flange (key 102) on the shaft. Then lubricate and install the packing nuts (key 101), hand tightening them. Apply lubricant to the stud threads, internal nut threads and contacting face of the nut. Packing flanges with flats on the sides may need to be oriented with the mounting bracket so the flange will fit between the legs of the bracket.

8. To obtain optimum maximum benefit from the packing system, tighten the packing flange nuts and compress the Belleville springs to their Target Load. The Belleville springs are designed to provide optimum performance at their Target Load, 85% of their maximum deflection/compression.

To obtain the Target Load compression, tighten the packing flange nuts alternately and evenly, keeping the packing flange parallel with the valve flange, until the Belleville springs are compressed 100%. Then loosen each packing flange nut one half turn (180_ of rotation).

Actuator Mounting

Use the appropriate actuator instruction manual and figure 10 of this instruction manual when changing actuator styles and positions. The actuator may be either right- or left-hand mounted. Figure 10 shows the correct lever/shaft orientation for both left-hand mounting and right-hand mounting configurations.

Travel Adjustment

Actuator travel adjustment can be performed with the valve either in or out of the pipeline. Key numbers referenced in the following procedures are shown in figure 11 for single seal and flow ring constructions and in figure 12 for dual seal constructions.

D For valve assemblies in the pipeline:

1. Rotate the ball (key 2) to either the open or closed position as indicated by the travel indicator scale (key 37) on the outboard end of the valve.

2. Adjust the actuator as described in the appropriate actuator instruction manual until the arrow stamped on the end of the follower shaft (key 7) is fully aligned with the open or closed position on he travel indicator scale.

D For valve assemblies out of the pipeline, proceed as follows:

1. Rotate the ball to the fully open position. The fully open position is achieved when the inside surface of the ball bore (key 2) is completely square with the line flange gasket surface of the seal protector ring (key 14) or flow ring (key

14).

2. Adjust the actuator as described in the appropriate actuator instruction manual until the inside surface of the ball bore is at right angles to the line flange gasket surface of the seal protector ring or flow ring.

3. Adjust the travel indicator scale (key 37) until the arrow stamped on the end of the follower shaft (key 7) is fully aligned with the open position.
