The swing check valves with counter weight and lever grant a good performance of the anti-hammer effect thanks to the presence of the counter weight, that acts automatically when the flow stops. These swing check valves can be applied for both horizontal and vertical installations. For installation in vertical flow lines, we recommend to turn the counterweight 90° clockwise, so that, when the valve is ready for use, the counterweight will be in horizontal position.
