Duplex Disc Wafer Check Valve

Spring-loaded dual-plate, short face-to-face, low slam.

As part of the VTXFLOW check valve range, the 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. VTXFLOW check valves prevent reverse flow automatically without external control. The line includes swing, lift, tilting-disc, dual-plate wafer and nozzle designs in bolted-cover and pressure-seal construction.

Optimized disc dynamics minimize slam and water hammer
Renewable seat rings on cast designs
Dual-plate design weighs up to 80% less than swing type
Cryogenic and NACE MR0175 options available
