Product characteristics
When there is no medium flowing through the valve body, the valve disc is always closed under the action of spring force. The opening, closing and opening degree of the valve disc mainly depends on the pressure difference at the inlet and outlet ends. If the pressure at the inlet end is greater than the sum of the outlet end and the spring, the valve disc opens. As long as there is a pressure difference, the valve disc is always in the open state. At the same time, the magnitude of the pressure difference determines the opening degree of the valve disc. If the total pressure and spring force at the outlet end is greater than that at the inlet end, the disc will always be closed, because the opening and closing of the disc is in a dynamic force balancing system, no matter how the medium at the inlet end changes, the valve will operate in a balanced manner, with no noise and few safety failures.
1. The flow path inside the valve body adopts streamlined design, and the head loss is small.
2. Reasonable, good sealing, wear resistance and long service life
3. It has guiding device, flexible closing and short disc closing journey. It can realize the quick closing of valve, prevent the silent effect of huge water hammer sound stroke, and run smoothly, without vibration, noise, safety, and rarely failures.
