ZSO Wafer Pattern Solid Disc Nozzle Check Valve

POA

The Noreva Non-Slam ZSO Nozzle Check Valve is designed with Solid Disc, Diffuser, Metal to Metal seat, Wafer Pattern with the shortest Face to Face dimension possible and up to 400 Bar MWP. The valve design includes a turbulent-free aerodynamic flow path and multiple Spring torque options. Although each valve is optimised for a Low Head Loss with a Fast Closing, Non-Slam and Flutter-Free performance the ZSO is used where pressure losses are not the main concern and weight and space are critical. With a Metal to Metal seat, no elastomers, no wearing parts and a WRAS approved Fusion Bonded Epoxy coating, the design is Maintenance Free and suitable for buried service. Specified for Potable Water Service in the UK Water Industry, it is compliant to WIMES 8.09i1 and DWI Regulation 31(4)(b).
