SPIRAX SARCO DCV41 Austenitic Stainless Steel Disc Check Valve DN25

Description The DCV41 is an austenitic stainless steel disc check valve available with either screwed or socket weld end connections. Its function is to prevent reverse flow on a wide variety of fluids for applications in process lines, hot water systems, steam and condensate systems. For oil and gas applications, a Viton seat is available. For water applications an EPDM seat is available. Soft seat versions provide a zero leakage rate or bubble tight shut-off, i.e. they meet EN 12266-1 Rate A, providing a differential pressure exists. Please note that the soft seat options are not available with socket weld ends. The shut-off of the standard valve conforms to EN 12266-1 Rate E. When a heavy duty spring is installed with an EPDM seat, the valve is suitable for boiler feedwater check applications. A high temperature spring version is available to operate at 400 °C.
