            application

              The bottom valve is a pneumatic seat valve with a hygienic and flexible design. Based on a proven single seat valve design platform, the small and simple moving parts make the valve very reliable and reduce its maintenance costs. Used to cut or open the pipe to the tank. Widely used in wine, dairy, beverage, pharmaceutical and other industries.

            working principle


            The valve uses compressed air to push the piston in the pneumatic actuator up, and also pulls the valve stem up when the air compression pushes the piston in the pneumatic actuator up, ie the valve opens. When the air compression is lower than the spring force or the gas is not compressed, the piston is pushed by the spring under the action of the spring, and the valve stem is moved downward to close the valve port.
