Description & Features

Check valve with counter weight is a double flanged and double eccentric valve used as a check valve that permits medium flow in only one direction and prevents the flow from reversing. The flow opens the valve in the desired direction, while back flow forces the valve to close. Full tightness is ensured by an elastomer-to-metal design. The valve is equipped with a disc position indicator. The operation is by means of a lever counter weight.

● Buffer device has appealing design, with compact structure and reliable performance. It is installed outside pipeline preventing medium from pollution.

● This couterweight type model is automatically cut off by gravitational potential energy of the couterweight hammer.

● Double offset bearing of the disk in the body in maintenance-free bushes

● Medium-free bearing by triple O-ring seal and closed bearing lugs at the disc

● Wear-resistant, corrosion-resistant and infiltration-proof seat

● Anti-blowout shaft and shaft seal
