Also known as gate valves, these valves gradually open and close to prevent system damage from suddenly starting and stopping flow.

Valves with a spring-close lever handle open when you pull on the handle and close when you release it. The handle is also called a deadman’s handle. Use these valves where the volume of flow needs to be closely monitored to avoid overflowing and spillage. Valves with a nonrising stem keep the stem in the same position whether they’re open or closed. They’re often used underground and in low-clearance locations.

Brass valves have good corrosion resistance. They also have a more polished look than bronze valves. However, they’ll corrode from salt water.

Flow coefficient (Cv) is the amount of water (in gallons per minute) at 60° F that will flow through a fully open valve with a difference of 1 psi between the inlet and the outlet.

Prevent boiler scale deposits and sediment buildup with these valves that meet ASME standards for boiler drainage applications. Also known as gate valves, they gradually open and close to prevent system damage from suddenly starting or stopping flow.

Valves with a lever handle open and close faster than valves with a wheel handle.

Cast iron valves absorb vibration, reducing noise from your industrial boiler. Steel valves resist corroding from the dirt and particles that come out of industrial boilers better than cast iron valves.

Use repair kits to replace worn-out seals.
