Lug Dual Plate Check Valve
Two arch disc are fixed onto the valve body with a spindle on which two torsional springs are equipped for installing the butterfly plate onto the valve body sealing face. The butterfly plate pressed by the springs is opened by relying on the medium pressure, and the valve is closed by the spring force and the medium pressure under backflow. It can be installed on horizontal and vertical pipelines.
