Introduction
Scope of Manual
This instruction manual provides installation, operation, maintenance, and parts information for the Fisher V280
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 V280 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
Description
The Fisher V280 is a three-piece, trunnion mounted, full-bore control valve designed with features for optimized
pressure, flow, and process control. The V280 comes standard as a single-seal construction with optional dual-seal
construction allowing for bidirectional flow and double block-and-bleed operation, with or without attenuation. Valve
constructions with attenuators combine the efficiency of a rotary valve with the noise reducing capability of a special
trim. Valve constructions without attenuators present little or no restriction to flow at full travel. The V280
construction meets ANSI/NACE MR0175/ISO 15156 as standard.

To electrically bond the drive shaft to the valve body for hazardous area service, an alternate shaft-to-body bonding strap can be provided by using the follow step (see figure 2). -
Page 6: Packing Maintenance
Instruction Manual V280 Valve August 2019 D104425X012 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. - Page 7 Instruction Manual V280 Valve D104425X012 August 2019 Refer to figure 3 which identifies the V280 packing components by key number (also see the Parts List section of this manual).

Provide a clean soft working surface to protect the tailpiece‐flange serrated surface. Lift the valve and place it on either tailpiece flange face. Be sure the valve is in a stable, upright position before releasing the hoist connection. Note If the packing (key 105) is in good condition, it is possible to remove and replace the seal assembly (key 5) without removing the packing box housing assembly.
