Fisher Butterfly Valves

Product Overview

Fisher butterfly valves are a rotary valve featuring an eccentrically mounted disc with shut-off capability: suitable for an extensive range of flow control and isolation applications.

Butterfly valves are available in NPS 2 -72 sizes with cryogenic, high temperature and pressure classes to ASME CL2500.

High-performance Fisher butterfly valves are designed for isolation on/off service and low-tier control.

Butterfly valves feature keyed, double D, or square valve shafts. Shutoff is provided by a variety of seals which include metal, PTFE and fire-tested and cryogenic.

Why FISHER Butterfly Valves?

Fisher butterfly valves require minimum space for installation while providing high flow capacity with low pressure loss via the valves. The butterfly valve can mate with standard raised-face pipeline flanges. Smaller size butterfly valves can use diaphragm or piston pneumatic actuators, including rotary actuators. Larger valves may require high-output electric or long stroke pneumatic cylinder actuators.

• Conventional contour discs – throttling control up to 60-degree risk rotation
• Streamlined contour discs – throttling control up to 90-degree risk rotation

Control valves are used in pipelines to provide flow, pressure, temperature and liquid level control of gases, steam, water, chemicals or hydrocarbons in industrial process and hazardous area located pipes.
