application

  This tank bottom valve is a sterile diaphragm type 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 high-grade dairy products, beverages, pharmaceuticals and other industries.

working principle

The valve uses compressed air to push the piston in the pneumatic actuator down, while pushing the valve stem down, pulling the diaphragm to open the valve port, that is, the valve is open. 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 rod is moved up, and the diaphragm is closed against the diaphragm. The valve is also a sterile down-spread discharge valve.
