About Gradual On/Off Valves

Threaded Gradual On/Off Valves

High-Pressure Threaded Gradual On/Off Valves

Designed for use in refineries and other demanding environments, these durable valves have a forged steel body that can withstand at least twice the pressure of other threaded valves.

Plastic Threaded Gradual On/Off Valves

Threaded Gradual On/Off Valves for Boiler Blow-Off

Prevent boiler scale deposits and sediment buildup with these valves designed to meet ASME standards for boiler drainage applications.

Flanged Gradual On/Off Valves

Flanged Gradual On/Off Valves
for Thick Liquids and Dry Materials

These valves have a sharp gate that slices through thick slurries, wastewater, dry bulk solids, and other materials that would clog other gradual on/off valves.

High-Pressure Socket-Connect Gradual On/Off Valves

With a forged steel body and bolted construction, these durable valves can withstand nearly 10 times the pressure of other socket-weld gradual on/off valves.

Plastic Socket-Connect Gradual On/Off Valves

Socket-Connect Gradual On/Off Valves

Gradual On/Off Valves with Solder-Connect Fittings

Threaded Gradual On/Off Valves for Drinking Water

These valves have NPT connections for use with threaded pipe.

Socket-Connect Gradual On/Off
Valves for Drinking Water

Bond the socket-weld connections on these valves to unthreaded male plastic pipe.

Socket-Connect Gradual On/Off Valves for Chemicals

These valves have socket-weld connections for bonding to unthreaded male plastic pipe.

Threaded Gradual On/Off Valves for Chemicals

For use with threaded pipe, these valves have NPT connections.

Gradual On/Off Valves with
Quick-Clamp Fittings for High Vacuum

Also known as vacuum isolation valves, these block flow so you can install and remove gauges from your system. They can also be used to add or vent gases in high-vacuum systems.

Compressed Air Control Valves

Two-Action Air Directional
Control Valves with Full Shut-Off

These valves close all ports in the off position to stop equipment in a locked position with air pressure holding it in place. Also known as 4/3 closed-center valves, they create two actions, such as extracting and then retracting a double-acting cylinder.

Two-Action Air Directional Control
Valves with Exhausting Shut-Off

In the off position, these valves exhaust all air pressure, allowing the equipment to return to the neutral position. Also known as 4/3 exhaust-center valves, they create two actions, such as extracting and then retracting a double-acting cylinder.

Safety-Lockout Air On/Off Valves

A padlock locks the handle of these valves in the shut-off position so you can disconnect air tools safely.
