Check Valve with Counterweight is a double flanged double eccentric valve that acts as a check valve that allows the media to flow in only one direction, preventing flow reversal. Flow causes the valve to open in the desired direction, while recirculation forces the valve to close. The elastomer's metal design ensures complete tightness. The valve is equipped with a position indicator. The operation is done by lever weighting.
The swing-type check valve with counterweight and lever has good anti-hammer effect due to the presence of the counterweight, and automatically acts when the flow stops. These swing check valves are available for both horizontal and vertical installation. For installation in vertical flow lines, we recommend rotating the counterweight 90° clockwise so that when the valve is ready for use, the counterweight will be in a horizontal position.
