Gradual On/Off Valve
Manufacturer part: 4974K85
Rated for use in drinking water systems, these valves meet NSF/ANSI 61. They gradually open and close with multiple turns of the wheel handle to prevent system damage from suddenly starting and stopping flow. All have a nonrising stem that stays in the same position whether the valve is open or closed.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.
