  • DESCRIPTION

     Principle of pneumatic flange gate valve:

     The upper part of the cylinder head is equipped with a pneumatic-manual conversion device. Lift the conversion handle clockwise to the "pneumatic" positioning hole, and the gate valve is in pneumatic operation; conversely, lift the conversion handle counterclockwise to the "manual" positioning hole, and the gate valve can be operated manually. Handles with bevel gears switch in the opposite direction. When manually operating the gate valve, the handwheel rotation direction is the same as that of an ordinary manual valve, that is, clockwise to close and counterclockwise to open. Bevel gears rotate in reverse.
