The most basic option for air and inert gas applications.

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

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.

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.

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

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

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

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

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.

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.

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.

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

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

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

Valves have a brass body.

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.

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

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.

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

Set a specific pressure and these valves will maintain it.

Attach these valves with NPT connections to threaded pipe.

Prevent dirty, contaminated water from backing up into your garden hose line—install these valves between a faucet and a garden hose.

Solder these valves to copper tubing for a permanent, leak-tight connection.

Integral shutoff valves isolate flow for inline maintenance, and a top-entry cover provides easy access to internal components.
