Pneumatic Globe Valve

Pneumatic Globe Valve

Introduction:

The pneumatic globe valve adopts double acting cylinder, and the valve is remotely controlled by upper chamber air intake or lower chamber air intake, which is easy and flexible to operate. Cylinder medium: compressed air, nitrogen. Simple structure, convenient manufacturing and maintenance; Small working stroke and short opening and closing time; The sealing surface between the closing body (valve disc) and the valve seat is sealed by a cone, with small closing force, erosion resistance and reliable sealing. The valve seat can be a replaceable valve seat, which can be matched with the sealing surface material of the closing element in any combination to meet the requirements of working conditions and extend the service life.

Working principle:

Most of the valves using compressed air as the power source are remotely controlled. The main control room manually or automatically triggers the action command to make the inlet and exhaust solenoid valves act to supply and exhaust compressed air to the actuator. The compressed air acts on the piston or diaphragm to overcome the friction force of valve action and the spring force on the valve stem, so as to press down (for air loss to open the valve) or lift (for air loss to close the valve) the valve stem, and drive the valve core to move up and down to open or close the valve.
