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

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.
