Introduction

Scope of Manual

This instruction manual provides installation, maintenance, and parts ordering information for NPS 4 through 24

Fisher V250 valves (figure 1) that mate with ASME flanges. Other instruction manuals provide information covering

the actuator and accessories.

Do not install, operate, or maintain a V250 valve without being fully trained and qualified in valve, actuator, and

accessory installation, operation, and maintenance. To avoid personal injury or property damage, it is important to

carefully read, understand, and follow all the contents of this manual, including all safety cautions and warnings. If you

have any questions about these instructions, contact your Emerson Process Management sales office before

proceeding.

Description

The V250 valve is a flangeless rotary control valve used for high pressure, throttling or on-off control of liquid or gas

applications (see figure 1). These valves operate on a rotary motion input through a splined valve-shaft/actuator-shaft

connection for use with power or manual handwheel actuators. The single seal, dual seal, and flow ring constructions

are covered in this instruction manual.

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.

PAGE 6
V250 Valve Instruction Manual September 2013 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.
PAGE 7
Instruction Manual D100422X012 V250 Valve September 2013 Perform this procedure if there is leakage around the follower shaft (key 7). Such leakage is an indication that the shaft seal, which includes the seal and a backup ring, (key 16) must be replaced. The following procedure may be performed with the valve in the pipeline. 1. Isolate the control valve from the line pressure, release pressure from both sides of valve, and drain the process media from both sides of the valve.
PAGE 8
V250 Valve September 2013 Instruction Manual D100422X012 Note The valve shaft's sealing surfaces are critical in obtaining a good seal. If the valve shafts are scratched, nicked or worn, replace or repair the valve shaft before installing new shaft seals. Both seal rings, drive end and follower end, should be replaced at the same time. 1. Isolate the control valve from the line pressure, release pressure from both sides of valve, and drain the process media from both sides of the valve.

Instruction Manual V250 Valve D100422X012 September 2013 WARNING The ball (key 2) closes with a shearing motion. To avoid personal injury, keep hands, tools, and other objects away from the ball while stroking the valve. CAUTION Damage to the ball (key 2) may occur if the ball is not in the fully open position while the valve is being removed from the pipeline. If necessary, pressure the actuator temporarily to retain the ball in the open position while removing the valve from the pipeline. 2.

Instruction Manual D100422X012 V250 Valve September 2013 5. Measure the clearance between the flow ring and the ball with a wire gauge. Add or subtract shim seals until the minimum clearance is 0.38 mm (0.015 inches) for valves used for forward flow and 0.76 mm (0.030 inches) for reverse flow. 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).
