DCV41 is an austenitic stainless steel disc check valve with 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 oils and gases, a FKM seat is available and for water an EPDM seat is available. Soft seat versions provide a zero leakage rate or bubble tight shut-off, i.e. they meet DIN 3230 BN1 and DIN 3230 BO1, provided a differential pressure exists (Note: Soft seat options are not available with socket weld ends). The shut-off of the standard valve conforms to DIN 3230 BN2. When a heavy duty spring is installed with an EPDM seat, the valve is suitable for boiler feed water check applications.
