Noreva - Model Type ZS -Solid Disc for Nozzle Check Valve

With a shorter face-to-face (wafer type) than the ZB and where pressure loss across the valve is not such a significant consideration, the ZS is installed where space and weight is at a premium. This type is only available on special request. Materials according to customers request, such as Low Temperature Carbon Steel, Nickel-Aluminium-Bronze, Duplex, Superduplex, 6Mo, etc. are our speciality!
