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.

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.

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.

Design a valve specifically for your process media and set pressure. Choose from a valve for air, inert gas, water, hydraulic oil, fuel oil, gasoline, or diesel fuel and a set pressure.

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

With a three-port design, these valves allow inline flow from the inlet to the outlet during normal conditions and divert flow through the relief port in overpressure conditions. They are often used with feed pumps for fertilizers and bleach.

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.

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

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

Often used in wet conditions and harsh environments, these valves have a 316 stainless steel body for excellent corrosion resistance.

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

Often used on dispensers, humidifiers, and fountains, these valves have a 316 stainless steel body that can stand up to deionized water and corrosive conditions.

Excellent performance at low pressures.

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.

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.

Valves have a brass body.

Our smallest pressure-regulating valve.

Regulate pressure in air and inert gas systems from your instrument panel—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.

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

These valves automatically reduce a high inlet pressure from compressed gas tanks to a lower, stable outlet pressure.

Designed for nitrogen gas purging in air conditioning, refrigeration, and plumbing systems.

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

Control steam line pressure with ±1 psi accuracy.

Valves have NPT connections.

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.

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.

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.

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

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.

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

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

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

Instead of exhausting discharge directly, these discs have a threaded relief port for attaching a drain line to direct discharge away from your work environment.

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

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

These valves maintain a consistent pressure in a system when input pressure varies.
