Prevent boiler scale deposits and sediment buildup with these valves that meet 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.

Bolt these valves to flanges. They gradually open and close to prevent system damage from suddenly starting and stopping flow.

Epoxy-coated cast iron valves are more corrosion resistant than plain cast iron or steel valves.

316 stainless steel valves have the best corrosion resistance.

Wheel handles open and close with multiple turns, providing more controlled, shock-resistant flow than pull handles.

Nonrising stems stay in the same position whether the valve is open or closed. Valves with nonrising stems are often used underground and in other low-clearance locations.

Rising stems lift as the valve opens and lower as the valve closes to provide a visual indication of whether flow is on or off. The stem is isolated from the process media for a longer service life than valves with a nonrising stem.

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.
