The most basic option for air and inert gas applications.

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.

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.

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

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

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

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

Choose these valves for small steam-heating boilers requiring pressure relief between 5 psi and 12 psi.

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

Less than a quarter of the height of standard pressure-relief valves, these are often installed on tanks in low-clearance areas.

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.

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.

These valves are often used in hydraulic and lubrication systems.

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

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

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

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.

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

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.

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

For extremely high-pressure applications in tight spots, these valves handle the same inlet pressures as other ultra-high-pressure-regulating valves within a smaller footprint.

A 316 stainless steel body provides exceptional corrosion resistance in wet conditions and harsh environments.

Withstand inlet pressures up to 3,500 psi.

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

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

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.

Commonly used in TIG welding where gas flow/coverage is a concern.

A 316 stainless steel body provides exceptional corrosion resistance in wet conditions and harsh environments.

Control steam line pressure with ±1 psi accuracy.

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

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.

For use with acetylene, hydrogen, methane, propane, or propylene gas.

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.

These valves have a cast iron body.

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

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

Install these discs within the bolt circle of ANSI Class 150 flanges.

A lighter and more corrosion-resistant alternative to metal vacuum-regulating valves.

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

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

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

Set a specific pressure and these valves will maintain it by diverting excess fluid to a tank.

Quickly vent exhaust air to the atmosphere or divert it to another place in your system to speed up the movement of equipment. The 90° elbow shape allows you to install them in tight spaces. Also known as quick exhaust valves.

A muffler reduces exhaust noise. Valves allow airflow into your equipment and then quickly dump exhaust air to the atmosphere without routing it back through a directional control valve to speed up the movement of equipment. Also known as quick exhaust valves.

Choose the pressure range you need. When these valves receive an air signal, they quickly dump exhaust air to the atmosphere without routing it back through a directional control valve to speed up the movement of equipment. They're often used with air compressors that require continuous operation. Also known as quick exhaust valves.
