Wafer Check Valve K6 (PVC-U)
Description
K6 wafer check valve made of PVC-U (grey) for wafer-style installation between flanges (DIN/ANSI), DN40 to DN350, EPDM or FPM seal, MOP up to 10 bar. Conical sealing face and back-flushed, cylindrically mounted disc shaft for high loads; optionally without spring or spring-loaded (operating temperature up to 60 °C, spring material 1.4401/AISI 316).
