Q-type pneumatic tank bottom valve

application

This tank bottom valve is a pneumatic seat valve with a hygienic and flexible design, based on a mature single seat valve design platform. The few and simple moving parts make the valve very reliable and reduce its maintenance costs. Used to cut or open pipelines leading to storage tanks. Widely used in industries such as brewing, dairy products, beverages, pharmaceuticals, etc.

operational principle

This valve uses compressed air to push the piston inside the pneumatic actuator up, and at the same time, when the air compression pushes the piston inside the pneumatic actuator up, it also pulls the valve stem up, that is, the valve opens. When the air compression is lower than the spring force or there is no gas compression, the piston is pushed down by the spring and drives the valve stem to move down, closing the valve port.
