These valves meet ASME Code Section VIII for use with water pressure vessels.

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

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.

For use with low-pressure steam-heating boilers requiring pressure relief at 15 psi, these valves meet ASME Code Section IV.

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.

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.

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.

Withstand more than six times the inlet pressure of standard pressure-regulating valves.

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.

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

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.

Valves have a brass body and NPT connections.

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

Excellent performance at low pressures.

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.

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

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.

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.

Choose from valves for liquid argon, liquid nitrogen, liquid carbon dioxide, or liquid oxygen tanks.

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.

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.

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

Use these valves in pipelines.

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.

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

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

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

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

The pressure setting on these valves cannot be adjusted while they are installed.

Set a specific pressure and these valves will maintain it.

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.

Control the flow of exhaust air while also regulating the exhaust air speed. These valves dump exhaust air to the atmosphere without routing it back through a directional control valve. The 90° elbow shape allows you to install them in tight spaces. Also known as quick exhaust valves.

Install these valves in the exhaust ports of air directional control valves to control exhaust air speed without needing access to your cylinder.
