K4 PVC Check Valve Wafer Type

K4 PVC Wafer Check Valve Characteristics: • • simple and robust design • • maintenance free • • valve disc position indication • • available with or without position indication pin • • very low pressure loss because of big aperture angle of the disc 83° • • full disc opening also in PP and PE piping systems guaranteed • • models with spring package ( 2 springs PN10, big spring PN 7 and small spring PN3) allows adaptation of the wafer check valve to the pressure range within the system • • simple installation between flanges through attached eyelets ( DIN; ANSI; JIS) and frontal O-rings. • • no more discharge help required • • up to 50% higher flow rates compared to type S460, S470 • • minimal pressure loss • • higher operating pressures Operating temperature: max. 60 ° C
