Introduction

Scope of Manual

This instruction manual provides installation, operation, maintenance, and parts information for the Fisher V270
Full-Bore Ball control valve (see figure 1). Refer to separate manuals for information concerning the actuator,
positioner, and accessories.

Do not install, operate, or maintain a V270 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 sales office

Description

The Fisher V270 is a three piece, trunnion mounted, full-bore control valve designed with features for optimized
pressure, flow and process control. The V270 comes standard with dual seal construction allowing unidirectional or
bidirectional flow and double block-and-bleed operation. The full-bore ball design presents little or no restriction to
flow at full travel. The V270 construction meets ANSI / NACE MR0175 / ISO 15156 as standard.

Installation

WARNING

D To avoid personal injury, always wear protective gloves, clothing, and eyewear when performing any installation

operations.

D To avoid personal injury or property damage resulting from the bursting of pressure retaining parts, be certain the

service conditions do not exceed the limits given in this manual.

D To avoid personal injury or property damage that can result from the sudden release of process pressure if valve or

mating pipe flange pressure ratings are exceeded, provide a relief valve for over‐pressure protection as required by
government or accepted industry codes and good engineering practices.

D Personal injury could result from packing leakage. See the Packing Maintenance section for adjustment information.

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

media.

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

instruction manual.

D Use proper lifting and rigging practices while moving the valve or valve/actuator assembly.

V270 Valve

September 2018

Key number locations are shown in figures 4, 5 and 6, unless otherwise noted. Throughout this manual, the
component key number will be identified for clarity.

1. Install a three‐valve bypass around the control valve assembly if continuous operation will be necessary during

inspection and maintenance of the valve.

2. The valve is normally shipped as part of a control valve assembly, with a factory adjusted actuator mounted on the

valve. If the valve or actuator has been purchased separately, or if the actuator has been removed, refer to the
Actuator Mounting section and the appropriate actuator instruction manual for installation and adjustment
procedures.

3. The standard valve construction allows uni-directional or bi-directional flow. If possible, install the valve in a

horizontal pipeline with the drive shaft vertical, however, the orientation of the valve does not affect the
performance.

CAUTION

Be certain the valve and adjacent pipelines are free of any foreign material that could damage the valve sealing surfaces.

4. Provide appropriate flange gaskets, and place the valve in the pipeline. Tighten flange bolting in a star pattern to

ensure the flange gaskets are compressed evenly.

Note

Standard Fisher V270 live-loaded PTFE packing is composed of partially conductive packing rings (carbon‐filled PTFE male and
female adaptors) to electrically bond the drive shaft to the valve body. For hazardous area service, an alternate shaft‐to‐body
bonding strap is also available by using the following step (see figure 2).

5. For hazardous area applications where redundant shaft-to-body grounding is preferred, attach the optional

bonding strap assembly (key 45) to the valve drive shaft (key 4) with the clamp (key 44) and connect the other end
of the bonding strap assembly to the valve body with the mounting cap screw as shown in figure 2.

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.

WARNING

Avoid personal injury or equipment damage from sudden release of process pressure or uncontrolled movement of parts.
Before performing any maintenance operations:

D Do not remove the actuator from the valve while the valve is still pressurized.

D Do not loosen any pressure retaining bolting while the valve is still pressurized. This includes the body to tailpiece nuts

(key 21), packing box housing screws (key 10), packing nuts (key 36) or pipe plugs (keys 23 and 28).

D Avoid injury by keeping hands, tools, and other objects away from the ball while stroking the valve.

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. Check the

actuator cannot suddenly open or close the valve.

D Vent the power actuator loading pressure and relieve any actuator spring precompression.

D Use bypass valves or completely shut off the process to isolate the valve from process pressure, relieve any process

pressure from both sides of the valve body, and drain the process media from both sides of the valve.

D Dual‐seal constructions can retain pressure and process fluid even after process pressure has been removed from both

sides of the valve. The ball should be partially opened to relieve this pressure before disassembling or removing the
valve from the line. Take additional care if the process fluid is hot, flammable, caustic, or hazardous.

D A tip over hazard exists for the valve/actuator assembly. Ensure the valve/actuator assembly is properly secured and

always supported to prevent falling or rolling which may cause injury or property damage.

D Use lock-out/tag-out best practices and procedures to be sure that the above measures stay in effect while you work on

the equipment.

D The valve packing box housing 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.

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

media.

Packing Maintenance

Refer to figure 3 for details of the standard live-loaded PTFE packing. All maintenance operations in this section may be
performed on an unpressurized valve that is still installed inline.

Note

For additional information on the live-loaded packing system refer to the ENVIRO-SEAL Packing System Instruction Manual
(D101643X012

Stopping Leakage

Optimum performance of the PTFE live-loaded packing system is obtained when the Belleville springs are compressed
to the required “target load.” The target load is the point where the springs are compressed to 85% of their maximum
deflection.
