The CSA direct acting pressure reducing valve Mod. VRCD-M reduces and stabilizes the downstream pressure to a constant value, regardless of flow rate and upstream pressure variations. It can be used for water and fluids in general. Entirely made in ductile cast iron and mobile block in stainless steel, suitable for PN 10/16 bar pressure rating applications, VRCD-M is provided with a diaphragm for a larger surface of pressure regulation and increased accuracy.
