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.

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.

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

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

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

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 in hydraulic and lubrication systems.

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

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

Withstand inlet pressures up to 3,500 psi.

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.

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

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.

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

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

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.

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.

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

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

Valves have NPT connections.

Install these valves directly in gas distribution pipelines.

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 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.

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.

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.

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

These valves have a cast iron body.

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.

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

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

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

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

Set a specific pressure and these valves will maintain it.

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

These breather vents are rated NEMA 6 to withstand periodic submersion in water.

Secure access to vented openings in pipe and tanks—the cap can be locked to prevent tampering.

Shield outdoor pipe and tank openings from the environment. Also known as vent caps, these breather vents have screens to allow air flow while blocking debris.

Keep moisture, dirt, and debris from entering your oil reservoirs.

Use these vents to maintain consistent pressure as temperatures fluctuate by allowing air to flow through sealed enclosures.

Rated NEMA 4X, these vents provide protection from washdowns, corrosion, and power jets of water.

These vents maintain air pressure inside enclosures that may be exposed to indoor and outdoor temperature changes while keeping dust and water out.

Rated for 12 times the pressure of standard vacuum-breaking valves, these can handle up to 1,500 psi. Connections are NPT.

A plastic body withstands pH neutralizing, cleaning, and plating solutions containing sodium hydroxide, methyl ethyl ketone, and other harsh chemicals.
