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

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

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

Body is cast iron.

Control steam line pressure with ±1 psi accuracy.

A plastic body and fluoroelastomer seal stand up to harsh chemicals.

These valves are commonly used with pumps in low-pressure water systems.

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 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.

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.

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