Product Description

1. Pneumatic globe valve is a valve with compressed air as the power source. It adopts remote control, and the main control room manually or automatically triggers the action command to make the intake and exhaust solenoid valves act to supply and exhaust compressed air to the actuator. Compressed air acts on the piston or diaphragm, overcoming the friction of valve action and the spring force on the valve stem, so as to press (open the valve for gas loss) or lift (close the valve for gas loss) the valve stem, driving the valve core to move up and down, so as to open or close the valve. 2. When the valve loses gas and there is no compressed air in the driving head, the valve will be in a safe position of full open or full close according to the requirements of the system. Compressed air for instrument in power plant, the supply pressure is generally 4~9bar. Before entering the valve, the compressed air is filtered and purified by a filter, and then decompressed by a pressure reducing valve, and the reading of the inlet pressure gauge is no more than 4bar. Pressure adjustment can be achieved by adjusting the adjusting screw installed at the top of the pressure reducing valve. Before adjustment, loosen the protective cover.
