About Pressure-Relief Valves

Stainless Steel Steam Traps

Also known as thermostatic steam traps, these increase the efficiency of your radiator by venting cool air.

Sanitary Stainless Steel Steam Traps

Suitable for food, pharmaceutical, and other sanitary environments, these steam traps are made of 316 stainless steel with a Viton® fluoroelastomer O-ring to stand up to frequent washdowns with harsh cleaners and sanitizers.

Energy-Saving Stainless Steel Steam Traps

Also known as thermodynamic steam traps, these discharge condensate when close to steam temperature for minimal energy loss.

Sanitary Energy-Saving Stainless Steel Steam Traps

When close to steam temperature, these traps—also called thermodynamic steam traps—release condensate from steam lines to save energy in food, pharmaceutical, and other sanitary environments.

High-Flow Stainless Steel Steam Traps

Also known as inverted-bucket steam traps, these provide near-continuous discharge to accommodate high condensate levels.

High-Flow Iron Steam Traps

Also known as inverted-bucket steam traps, these provide near-continuous discharge to accommodate high condensate levels.

Energy-Saving Iron Steam Traps

Also known as thermostatic steam traps, these vent cool air and condensate to increase energy efficiency in your steam lines.

Brass and Bronze Steam Traps

These steam traps offer good corrosion resistance.

Pressure and Vacuum Control Valves

Air-Release Valves for Steam

Our only air-release valves for steam, these seal shut when steam enters the valve to prevent system contents from escaping through the relief port.

Fast-Acting Pressure-Relief Valves
for Ultra-Low-Pressure Steam

Choose these valves for small steam-heating boilers requiring pressure relief between 5 psi and 12 psi.

ASME-Code Fast-Acting Pressure-Relief
Valves for Low-Pressure Steam

For use with low-pressure steam-heating boilers requiring pressure relief at 15 psi, these valves meet ASME Code Section IV.

ASME-Code Fast-Acting
Pressure-Relief Valves for Steam

These valves meet ASME Code Section I for use with steam power boilers requiring pressure relief above 15 psi.
