Prevent boiler scale deposits and sediment buildup with these valves that meet ANSI and ASME standards for boiler drainage applications. They gradually open and close to prevent system damage from suddenly starting or stopping flow.

Wheel handles open and close with multiple turns, providing more controlled, shock-resistant flow than lever handles. They have a nonrising stem that stays in the same position whether the valve is open or closed.

Lever handles open and close faster than wheel handles.

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.
