The opening and closing of the disc is determined by the pressure difference between the valve inlet and outlet ends. The disc opens when the inlet pressure is large and the outlet pressure is the sum of the circulating spring force. As long as there is a pressure difference, the disc is always open, but the opening depends on the pressure difference. When the sum of the outlet pressure and spring force is greater than the inlet pressure difference, the disc closes and remains closed. Since the disc is open and closed in a dynamic force balancing system, the valve operates in a balanced, noiseless and water hammer manner. Rating: 150LB～2500LB
