The GD-24 Series of Pressure Reducing Valves from Yoshitake are a small and compact Pressure Reducing Valve designed especially for Cold & Hot Water applications. All wetted parts are made from corrosion-resistant material to prevent rusty water downstream from the valve. This pressure reducing valve is direct acting and is a hanging type which allows this valve to have no sliding parts, meaning greater performance due to less wear on internal parts. The GD-24 has a closed structure which keeps the fluid contained within the valve, even if the diaphragm is damaged or broken. This valve is easliy installed in horizontal or vertical piping and can be run in parallel with multiple valves for a larger flow capacity. Maximum pressure reduction ratio of 10:1.
