Noreva - Model Type ZB & ZD -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!
