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.

Rated for more than double the temperature of standard pressure-regulating valves, these can withstand temperatures up to 550° F.

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

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

These valves have a cast iron body.

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 with catalysts, pH buffers, and electroplating solutions.

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.

These valves meet ASME Code Section I for use with steam power boilers requiring pressure relief above 15 psi.

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