Model Number: H44-1 Key Specifications/Special Features: Swing check valve features:Valve is closed by the reversing flow medium and the weight and there is a damper on the valveValve is closed by two stages of quick and slow closing which prevents the pump from turning back and super high water hammer pressureWeight on the shaft balance the force during opening to reduce the flow resistanceThis kind of valves are automatic type which are opened by the pressure of the medium and closed by the reversing flowWater hammer rising has been taken into consideration during design so it is reliableDuctile Iron check valve design structure and features:Design: BS5153 DIN3202 F6Face-to-face: BS5153/DIN3202 F6Type: swing type,tilting disc typeMaterial:Body: ductile Iron GGG50 /GG25Disc: ductile Iron GGG50 /GG25Shaft: SS304Sealing: brassCoating spray: internally and externally coated with Epoxy by electrostatic coating
