During the use of pneumatic valves, metal pneumatic fittingsare usually required to improve the performance of pneumatic valves or to improve efficiency of pneumatic valves.

Metal pneumatic fittingscommonly found in pneumatic valves include air filters, reversing solenoid valves, limit switches, electrical positioners, etc. . In pneumatic technology, three kinds of air source processing components, including air filters, pressure-reducing valves, and oil mist devices, are assembled, the air source used to enter the pneumatic instrument is purified, filtered and decompressed to the rated air source pressure of the instrument supply, which is equivalent to the function of the power transformer in the circuit.

Metal pneumatic fittingstypes:

Double-acting pneumatic actuator: two-position control for valve opening and closing. (double action)

Spring-return actuator: in-circuit gas cut off or fault, the valve automatically opens or close. Single Action

Single electronic control solenoid valve: power supply when the valve opens or closed, closed or opens when the power cut (explosion-proof can be provided).

Double electric control solenoid valve: one coil when the valve is open, the other coil when the valve is closed, there is memory function (can provide explosion-proof).

Limit switch repeater: remote transmission of the valve switch position signal (can provide explosion-proof).

Electrical positioner: according to the current signal (standard 4 -20 Ma) the size of the valve medium flow regulation control (can provide explosion-proof).

Pneumatic positioner: according to the pressure signal (standard 0.02-0.1 mpa) the size of the valve medium flow regulation control.

Electrical converter: the current signal into a pressure signal, and pneumatic positioner supporting the use (can provide explosion-proof type).

Air source treatment triplet: including air pressure relief valve, filter, oil mist, on gas pressure, cleaning, and lubrication of moving parts.

Manual operating mechanism: the automatic control can be operated manually under abnormal conditions.

These are the types of metal pneumatic fittings. If you have any requirements, please feel free to contact us.
