About Pressure-Relief Valves

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.

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

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

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.

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.

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.

Precision-Adjustment
Pressure-Relief Valves for Water

Change set pressure without guesswork—the adjustment screw is marked in 25 psi increments for making pressure adjustments without a gauge.

Precision-Adjustment
Pressure-Relief Valves for Fuel

A finely threaded adjustment screw lets you make precise set pressure adjustments.

Pressure-Relief Valves for Oil

These valves are often used in hydraulic and lubrication systems.

Pressure-Regulating Valves

Extended-Life Pressure-Regulating
Valves for Water, Oil, Air, and Inert Gas

For a longer service life than brass and cast iron valves, these have a durable bronze body.

Heavy Duty Pressure-Regulating
Valves for Water and Air

Thicker walls and a 304 stainless steel seal make these valves tougher than brass pressure-regulating valves.

Quick-Set Pressure-Regulating Valves for Water

Change outlet pressure without using a gauge—turn the dial to adjust the outlet pressure in 5 or 10 psi increments.

Extended-Life Pressure-Regulating
Valves for Cryogenic Liquids

For a longer service life than standard valves for cryogenic liquids, these have a durable bronze body. They’re for use with liquid argon, liquid carbon dioxide, liquid nitrogen, and liquid oxygen.

Extended-Life Pressure-Regulating Valves for Steam

For a longer service life than cast iron valves, these have a durable bronze body.

Pressure-Regulating Valves for Drinking Water

These valves meet NSF/ANSI 61 for use in drinking water systems.

Extended-Life Back-Pressure-Regulating
Valves for Water and Oil

For a longer service than cast iron valves, these have a durable bronze body and a 303 stainless steel seal.

Extended-Life Vacuum-Regulating Valves for Air and Inert Gas

Extended-Life Vacuum-Regulating
Valves for Air and Inert Gas

For a longer service life than brass vacuum-regulating valves, these are made of bronze for strength and durability.
