The final control element of your process loop
A control valve is the final control element in a process loop: it receives a signal from the controller and adjusts the flow of gas, steam, water or chemicals to keep a process variable — pressure, temperature, level or flow — as close as possible to its set point.
A control valve assembly combines a valve body, an actuator that moves the closure member, and instrumentation (such as a positioner) that turns the control signal into precise stem or shaft movement. Choosing the right body style, trim and materials for the service is what determines control accuracy, shutoff, noise, cavitation resistance and service life.
Reference: control-valve fundamentals — see the Fisher™ Control Valve Handbook (coming to Resources).

Fisher™ control valve families
The control-valve types we supply and support. Tell us the duty or the serial number — we'll quote the right valve or parts.
Globe · Sliding-stem Globe Control Valves
The sliding-stem workhorse of final control — precise throttling, the widest choice of trim, and pressure ratings to the most demanding services.

Angle · Sliding-stem Angle Valves
Sliding-stem control with a 90° change of direction — built for high-pressure, erosive and flashing service, and for piping where the valve doubles as an elbow.
Learn more →
Rotary · V-notch ball Segmented Ball Valves
V-notch rotary ball valves for wide rangeability and high-capacity throttling — the rugged choice for erosive, viscous and fibrous service with tight shutoff.
Learn more →
Rotary · Eccentric plug Eccentric Plug Valves
Rotary eccentric-plug valves that pair globe-valve ruggedness with rotary efficiency — the plug cams into and out of the seat for low friction, long life and tight shutoff in erosive, hard-to-handle service.

Butterfly · Double-offset High-Performance Butterfly Valves
High-performance butterfly valves for effective, economical throttling in large lines and high temperatures — with the Fisher™ Control-Disk™ design extending the control range to rival a segmented ball.

Globe · Three-way Three-Way Control Valves
Three-way globe valves for converging (blending) or diverging (diverting) service — one valve body that mixes or splits flow for thermal and blending control.

Severe service Severe Service Control Valves
Anti-cavitation, anti-noise and high-pressure-drop trim for the toughest control applications.

Special application Steam Conditioning & Desuperheating
Steam-conditioning and desuperheating valves that protect downstream equipment and improve thermal efficiency.

Genuine Fisher™ control valve spare parts
Keeping an installed valve in service rarely means a whole new valve — it means the right genuine part. We supply OEM trim sets, cages, seat rings, packing, bonnets, stems and gaskets so your control valves stay accurate and tight. A will-fit look-alike can quietly undermine control, shutoff and emissions compliance; genuine parts protect them.
Send us a serial number, model or service and our team will identify and quote the right Fisher™ control valve or parts.
