corrugated pipe gate Industrial Valves, also called door and valve is one of the most widely used, it is popular, is due to open and close in the process of friction surface, more durable, opening, manufacturing easy, convenient maintenance, not only applicable to the

low pressure, and is suitable for high pressure. It is the closing of the principle, rely on the valve rod pressure, sealing surface and the valve seat valve sealing surface fit closely, prevent medium circulation.

bellows gate valve only unidirectional flow medium, the installation direction.
