operational principle

Rotate the handwheel counterclockwise, and the thread transmission between the handwheel and the bracket pulls the valve stem downward, pulling the diaphragm to open the valve port, which means the valve opens. Rotate the handwheel clockwise, and the thread transmission between the handwheel and the bracket drives the valve stem to move up while also driving the valve stem to move up, pressing against the diaphragm to close the valve port. This valve is also a sterile downward spreading discharge valve.
