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.

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

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.

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

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

Alter the set pressure to suit your application.

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

For a low-pressure seal around plastic and soft metal tubing, these valves have push-to-connect fittings.

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

Cleaned and bagged for oxygen service and other high-purity applications, these valves are built to withstand the extreme cold of liquid carbon dioxide, liquid nitrogen, and liquid oxygen.

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

These valves automatically reduce a high, variable inlet pressure to a lower, stable outlet pressure.

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

Use this valve in light duty water systems with garden hose thread (GHT) connections.

To maintain contaminant-free standards in clean room environments, these valves come cleaned and bagged to Fed. Std. Class 100 and ISO Class 5 clean room standards and have a 316 stainless steel body with a smooth finish to resist dust collection.

Prevent changes to your pressure setting—these valves come set at a nonadjustable outlet pressure.

Hook up these valves to equipment with garden hose thread (GHT) connections.

Excellent performance at low pressures.

Often used for oxygen service and other high-purity applications, these valves are cleaned and bagged to meet CGA G-4.1 standards to prevent contamination.

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

Valves have a brass body.

Our smallest pressure-regulating valve.

For easy panel mounting in your water system, these valves have threads below the adjustment knob and come with a panel-mount nut.

Commonly used for oxygen service and other high-purity applications, these valves come cleaned and bagged to prevent contamination.

Flowmeters let you see the gas flow rate from a distance.

Often used for pressure-vessel testing and other high-pressure applications, these valves can handle at least seven times the outlet pressure of standard tank-mount pressure-regulating valves.

Reduce contaminants in gases used in research sample systems, emission monitoring systems, chromatography, and other high-purity applications. These valves have a 316 stainless steel and brass body with a smooth finish to reduce dust collection and internal components designed to protect the seal and diaphragm from contamination.

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

Control steam line pressure with ±1 psi accuracy.

Designed for oxygen service and other high-purity applications, these valves can withstand the extreme cold of liquid argon, liquid carbon dioxide, liquid nitrogen, and liquid oxygen.

Compression fittings bite down on hard metal and plastic tubing for a tighter seal than push-to-connect fittings.

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

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

Designed to reduce contaminants in high-purity applications using hydrogen and methane gas, these valves have a stainless steel and brass body with a smooth finish to reduce dust collection and internal components designed to protect the seal and diaphragm from contamination.

It's like getting four regulators in one—each comes with four springs so you can change between regulating pressure ranges of 2-30, 10-50, 30-90, and 100-180 psi.

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

Threads below the adjustment knob and an included panel-mount nut allow you to add these valves to your instrument panel.

Regulate vacuum levels from your instrument panel with these valves that have threads below the adjustment handle and a panel-mount nut.

For precise control over your vacuum level, these valves have ±0.1% accuracy.

These valves have a vented relief port to exhaust discharge directly.

Also known as fusible plugs, these discs have a metal core that melts at a set temperature to exhaust discharge directly.

To set the pressure, unscrew the cap and turn the adjusting screw.

An external nut lets you adjust the pressure without disassembling the valve.

When input pressure varies, use these valves to maintain a consistent pressure.
