Flow-Control Valves

Gradual On/Off Valves

Also known as gate valves, these gradually open and close to prevent system damage from suddenly starting and stopping flow.

On/Off Valves

On/Off Valves

Quickly start and stop flow with these valves.

Actuated On/Off Valves

Actuated On/Off Valves

Driven by compressed air or electricity, these valves automatically start and stop flow.

Flow-Adjustment Valves

testString

Gradually open and close these valves to adjust and regulate flow.

Diverting Valves

Divert flow between multiple ports.

Other Steam Valves

Pressure and Vacuum Control Valves

testString

Ensure safe, consistent, and efficient pressure in pipelines and tanks. These valves are available in relief, pop-safety, pressure-regulating, and air-release styles.

Temperature-Control Valves

To maintain a set temperature in your system, these valves add hot or cold water to compensate for temperature changes.

Steam Traps

Steam Traps

Remove condensate from steam lines and prevent steam loss.
