Noreva - Solid Disc for Nozzle Check Valve

Type ZB – The ZB is the standard valve for sizes 1” – 10”. Its optimum designed aerodynamic flow path through the valve results in very low pressure losses. It is also available with API 6D face-to-face dimensions (ZD). The axial design allows for a streamlined flow path around the disc and high pressure recovery, minimising pressure drop across the valve. This efficient design combined with the highly responsive nonslam operation make this valve ideal for high head, critical pump applications. Type ZB – The ZB is the standard valve for sizes 1” – 10”. Its optimum designed aerodynamic flow path through the valve results in very low pressure losses. It is also available with API 6D face-to-face dimensions (ZD). Materials according to customers request, such as Low Temperature Carbon Steel, Nickel-Aluminium-Bronze, Duplex, Superduplex, 6Mo, etc. are our speciality!

Noreva - 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!

ZO is available from DN25 to DN250 and in pressure classes PN 10 and PN 16 (other pressure classes are available upon special request), the face-to-face dimensions of the ZL type are in accordance with DIN EN 558-1. Materials according to customers request, such as Low Temperature Carbon Steel, Nickel-Aluminium-Bronze, Duplex, Superduplex, 6Mo, etc.
