About Pressure-Relief 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.

Vibration-Damping Pressure-Regulating
Valves for Water, Oil, Air, and Inert Gas

A cast iron body absorbs vibration from pressure changes to reduce wear and noise in your pipeline.

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.

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

Withstand more than six times the inlet pressure of standard pressure-regulating valves.

High-Temperature Pressure-Regulating
Valves for Water, Oil, Air, and Inert Gas

Rated for more than double the temperature of standard pressure-regulating valves, these can withstand temperatures up to 550° F.

Pressure-Regulating Valves for Steam

Body is cast iron.

Extended-Life Pressure-Regulating
Valves for Steam

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

High-Accuracy Pressure-Regulating
Valves for Steam

Control steam line pressure with ±1 psi accuracy.

Pressure-Regulating Valves for Drinking Water

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

Pressure-Regulating Valves for Chemicals

A plastic body and fluoroelastomer seal stand up to harsh chemicals.

Back-Pressure-Regulating Valves for Water and Oil

These valves have a cast iron body.

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.

Pressure-Relief Valves

Precision-Adjustment
Pressure-Relief Valves for Fuel

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

Adjustable Pressure-Relief Valves for Fuel

To gradually relieve pressure in lines for diesel fuel, fuel oil, gasoline, and kerosene, these valves begin opening at the set pressure and fully open at about 10% over the set pressure.

Pressure-Relief Valves for Water

These valves are commonly used with pumps in low-pressure water systems.

Adjustable Pressure-Relief Valves for Chemicals

These valves are often used with catalysts, pH buffers, and electroplating solutions.

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.

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 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 Hot Water

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

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.

Level Control

Float Valve Bodies for Water

Combine these float valve bodies with floats and rods to create float valves that meet exact specifications.

Float Valve Bodies for Chemicals

Often found in tanks that are frequently washed down, these float valve bodies are 316 stainless steel, so they resist corroding from harsh cleaners.

Bronze Float Valves

With a durable bronze body, these float valves can be used with water and hydraulic fluid.

Brass Float Valves

Use these float valves with water.

Compact Plastic Float Valves

Smaller than other float valves, these are sized for containers with limited space.
