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

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

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.

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.

A finely threaded adjustment screw lets you make precise set pressure adjustments.
