Product: pneumatic globe valves



Introduction


Pneumatic globe valve is an important actuation device in industrial automation control system, which can be controlled remotely and can meet the needs of computer program control in all sectors, including petrochemical industry, gas equipment, nuclear industry, power equipment, environmental protection water treatment, HVAC, Iron and steel metallurgy, brewing equipment, drying equipment, vacuum equipment, surface treatment, biopharmaceuticals, food machinery, textile printing, papermaking and other industries.


Features :


1. Simple structure, easy manufacture and maintenance;

2. The medium used in the cylinder is compressed air or nitrogen, which is safe and environmentally friendly;

3.  Cylinder uses the intake chamber or the lower chamber inlet to control valves remotely;

4. Short working stroke and short opening and closing time;

5. The sealing surface of the closing body (valve) and the valve seat adopts a conical seal, which has a small closing force, is resistant to scouring, and has a reliable seal;

6. The valve seat can be a replaceable valve seat, which can be arbitrarily combined and matched with the sealing surface material of the closing member to meet the requirements of working conditions and extend the service life.

Working principle

The pneumatic globe valve use compressed air as the power source for remote control. The main control room manually or automatically triggers the action command to activate the intake and exhaust solenoid valves to supply and discharge compressed air into the actuator. Compressed air acting on the piston to overcome the spring force and friction on the operation of the valve stem, such that pressure (p in loss of gas valve open) or lifted (off valves for gas loss) stem to drive the valve body move up and down, Open or close the valve.


When the valve loses air and there is no compressed air in the drive head, the valve will be in a fully open or fully closed safe position as required by the system. Compressed air for power plant instrumentation, the supply pressure is generally 4 ~ 9bar , before entering the valve, the compressed air is first filtered and purified through the filter, and then decompressed through the pressure reducing valve, the inlet pressure gauge reading does not exceed 4bar . Pressure adjustment can be achieved by adjusting the adjustment screw installed on the top of the pressure reducing valve. Before adjusting, loosen the protective cover.
