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

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

Prevent changes to your pressure setting—these valves come set at a nonadjustable outlet pressure.

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.

Our smallest pressure-regulating valve.

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.

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

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

Install these valves directly in gas distribution pipelines.

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.

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

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.

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

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.

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.

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

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.

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 vacuum-regulating valves, these are made of bronze for strength and durability.

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.
