Body is brass or nickel-plated brass. All meet ASME Code Section VIII for use with air and inert gas pressure vessels.

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.

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.

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.

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

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.

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.

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.

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.

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

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.

Valves have a brass body and NPT 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.

Withstand inlet pressures up to 3,500 psi.

Valves have a brass body.

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.

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

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.

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

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.

Valves have NPT connections.

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

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

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.

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.

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

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

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

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.
