Disc check valve

for waterdouble-flangelow-pressure

Tilting valves are installed in pumping systems to prevent backflow. The double eccentric design allows for very fast opening at low pressure. This also makes it suitable for systems with frequent flow and pressure variations. The adjustable lever/counterweight system allows for adjustment of the closing speed. All internal parts are made of stainless steel or epoxy coated 250 microns. Flowrates Tip Our shaft is trapezoidal : it enables a better positioning and the possibility of exchanging on-site the counter weight from the left to the right. Upon request, it is possible to provide this check valve with a protection cover for more safety Main Characteristics and Advantages of the Weighted Check Valve Low head losses. Maintenance free. Complete sealing (double eccentric arrangement of disc). Mounting horizontally or vertically. Bearings self lubrificated. Operation with or without counterweight. CONSTRUCTION MATERIALS: see chart.
