About Pressure-Relief Valves

ASME-Code Fast-Acting Pressure-Relief
Valves for Air and Inert Gas

Body is brass or nickel-plated brass. All meet ASME Code Section VIII for use with air and inert gas pressure vessels.

Fast-Acting Pressure-Relief Valves for Air and Inert Gas

The most basic option for air and inert gas applications.

Remote-Discharge ASME-Code Fast-Acting
Pressure-Relief Valves for Air and Inert Gas

These valves have a bronze body for durability and a long service life. All meet ASME Code Section VIII for use with air and inert gas pressure vessels.

Large-Diameter Remote-Discharge Fast-Acting
Pressure-Relief Valves for Air and Inert Gas

Commonly used with high-volume blowers, compressors, and air-powered conveyors, these valves quickly relieve a large amount of air in systems with a pipe size of 2 or greater.

Large-Diameter Remote-Discharge ASME-Code
Fast-Acting Pressure-Relief Valves for Air and Inert Gas

Commonly used with high-volume blowers, compressors, and air-powered conveyors, these valves quickly relieve a large amount of air in systems with a pipe size of 2 or greater. All meet ASME Code Section VIII for use with air and inert gas pressure vessels.

Adjustable Fast-Acting Pressure-Relief
Valves for Air and Inert Gas

Change set pressure to suit your application—this valve includes four interchangeable color-coded springs with different set pressure ranges.

Fast-Acting Pressure-Relief
Valves for Air with Gauge Port

Attach a pressure gauge to the 1/4 NPT female port on these valves.

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.

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.

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.

Fast-Acting Pressure-Relief
Valves for Cryogenic Liquids

Use these valves with liquid argon, liquid nitrogen, and liquid oxygen.

ASME-Code Fast-Acting Pressure-Relief
Valves for Cryogenic Fluids

Our only valves that meet ASME Code Section VIII for use with cryogenic pressure vessels. They are for use with argon, carbon dioxide, helium, hydrogen, methane, nitrogen, and oxygen.

ASME-Code Fast-Acting
Pressure-Relief Valves for Hot Water

Protect your water-heating system with these valves that meet ASME Code Section IV for hot water heaters and boilers.

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

These valves meet ASME Code Section VIII for use with water pressure vessels.

Fast-Acting Temperature- and
Pressure-Relief Valves for Hot Water

Also known as T & P valves, these open when water temperature reaches 210° F or at the set pressure.
