Check valve with lever and weight, type 4010

Check valve with lever and weight, type 4010

Type 4010 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 counterweight.
