About Actuated On/Off Valves

Easy-Maintenance High-Flow
Air-Driven On/Off Valves

The three-piece bolted body comes apart for access to internal components without unthreading pipe connections and removing the valve from your line.

High-Flow Air-Driven On/Off Valves

For use in general purpose applications with water, oil, and inert gas.

Heavy-Use High-Flow Air-Driven On/Off Valves

Limit wear and damage in high-cycling applications—these valves have additional seals that prevent leakage to reduce maintenance time.

Versa-Mount Air-Driven On/Off Valves

A compact, lightweight actuator and an angular body allow you to install these valves in any mounting orientation.

Compact Versa-Mount Air-Driven On/Off Valves

About half the height of our other versa-mount valves, these fit in tight spots.

Severe-Duty Air-Driven On/Off Valves

Also known as diaphragm valves, these have a diaphragm that can handle dirty liquid, slurries, and abrasive media without damage.

Compact Severe-Duty Air-Driven On/Off Valves

Less than half the height of standard severe-duty valves, these fit in small spaces and low-clearance pipelines.

Flanged Air-Driven On/Off Valves

Also known as butterfly valves.

High-Flow Flanged Air-Driven On/Off Valves

Their ball-valve design allows these valves to handle three times the flow of butterfly valves.

Versa-Mount Air-Driven On/Off Valves for Chemicals

Also known as piston valves, these have a compact, lightweight actuator that allows them to be installed in any mounting orientation. They’re often used in water-treatment applications.

High-Flow Air-Driven On/Off Valves for Chemicals

Also known as actuated ball valves, these provide higher flow rates than other air-driven valves.

Severe-Duty Air-Driven On/Off Valves for Chemicals

Also known as diaphragm valves, these have a diaphragm that can handle dirty liquid, slurries, and abrasive media without damage.

Flanged Air-Driven On/Off Valves for Chemicals

With a ball-valve design, these valves can handle three times the flow of butterfly valves.

Air-Driven On/Off Valves for Food and Beverage

For food and beverage applications that require frequent cleaning, these valves have quick-clamp connections, polished internal surfaces, and a three-piece bolted body for easy disassembly.

Sanitary Air-Driven On/Off Valves

Use air pressure to automatically control the flow of liquids in sanitary environments, such as food and beverage processing plants.

Air-Driven On/Off Valves for Fuel

Use these valves to safely transfer fuel and oil.

Air Actuators for Flow-Control Valves

Universal Air Actuators for Flow-Control Valves

Attach these actuators to manual ball valves, butterfly valves, and plug valves with an ISO 5211 hole pattern to automatically start and stop flow with compressed air.

Air-Driven Flow-Adjustment Valves

For faster actuation than motor-driven valves, these operate on compressed air. Integrate them into PLC systems for automatic control over the valve position based on system conditions. The actuator has a built-in electric pilot valve that controls the air supply to the valve. Set how much to open the valve using the programmable controller on the actuator.

Remote-Reading Temperature-Regulating Valves

Remote-Reading Temperature-Regulating
Valves for Water, Oil, and Steam

Body is bronze.

Compact Remote-Reading Temperature-Regulating
Valves for Water, Oil, and Steam

Nearly half the height of our other remote-reading temperature-regulating valves, these are often used in low-clearance areas.
