About Pressure-Relief 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.

Panel-Mount
Ultra-High-Pressure-Regulating
Valves for Air and Inert Gas

Valves have a brass body.

Panel-Mount
High-Pressure-Regulating
Valves for Air and Inert Gas

Withstand inlet pressures up to 3,500 psi.

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.

Threaded Pressure-Regulating
Valves for Food and Beverage

Valves have NPT connections.

Pressure-Regulating
Valves with Push-to-Connect
Fittings for Food and Beverage

Push-to-connect fittings form a low-pressure seal around plastic or soft metal tubing.

Sanitary Pressure-Regulating Valves

Regulate air, gas, liquid, and steam pressure on food, beverage, and pharmaceutical lines with these valves—they’re 3-A certified to meet sanitary design standards.

Sanitary
Back-Pressure-Regulating Valves

Designed to meet 3-A sanitary standards, these valves regulate liquid, gas, air, and steam pressure in hygienic zones of food and beverage plants.

Fast-Acting 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.

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

For corrosion resistance in wet conditions and harsh environments, these valves have a 303 stainless steel body. All meet ASME Code Section VIII for use with air and inert gas pressure vessels.

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.

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

With a 316 stainless steel body for exceptional corrosion resistance, these valves are often used in wet conditions and harsh environments. All meet ASME Code Section VIII for use with air and inert gas pressure vessels.

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.

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.

Sanitary Quick-Clamp Pressure-Relief Discs

Sanitary Quick-Clamp
Pressure-Relief Discs

If the pressure in your food or beverage line rises too high, these discs burst open to release the flow, preventing injuries and equipment damage.

Flow-Control Valves

Easy-Maintenance
Threaded Two-Stage
Backflow-Prevention
Valves for Drinking Water

Integral shutoff valves isolate flow for inline maintenance, and a top-entry cover provides easy access to internal components.

Threaded Two-Stage
Backflow-Prevention
Valves for Drinking Water

High-Pressure
Vacuum-Breaking Valves

Rated for 12 times the pressure of standard vacuum-breaking valves, these can handle up to 1,500 psi. Connections are NPT.

Vacuum-Breaking Valves
with Garden-Hose Fittings

Prevent dirty, contaminated water from backing up into your garden hose line—install these valves between a faucet and a garden hose.

Socket-Connect On/Off
Valves for Drinking Water

Insert unthreaded pipe into the socket ends and bond with primer and cement to create a permanent, leak-tight connection. These valves meet NSF/ANSI Standard 61, which means they’re safe to use with drinking water systems.

Frostproof Vacuum-Breaking
Valves with Garden Hose Threads

Stop backward flow in outdoor faucets with garden hose thread (GHT) outlets.
