Check Valve Series

Duplex Disc Wafer Check Valve

Twin spring-loaded half-discs close before flow reversal, virtually eliminating water hammer. The wafer body weighs up to 80% less than a swing check and fits between standard flanges.

As part of the VTXFLOW check valve range, every duplex disc wafer check valve is produced under our certified quality system — from in-house casting and CNC precision machining to 100% pressure and seat-tightness testing before shipment, with EN 10204 3.1 material certificates supplied.

Non-slam spring-assisted closure
80% lighter and shorter than swing type
API 594 / ASME B16.10 wafer & lug
Retainerless design available for zero body penetration
