Limit switch is an important accessory of pneumatic valve
The valve limit switch box is a field instrument used to detect the valve status in the automatic control system, which is used to output the opening or closing position of the valve as a signal of the switching value. The remote controller receives or the computer searches for sampling, and then executes the next procedure after confirmation. This product can also be used as an important valve interlock protection and remote alarm indication in the automatic control system.

The imported pneumatic valve has other accessories. Their functions and uses, as well as the selection of pneumatic valve accessories, are as follows
Inlet pneumatic valve In addition to pneumatic actuators and valves, some accessories are also needed, such as solenoid valves, air source processing triplets, limit switch annunciators, and positioning equipment for adjustable valves, which play an indispensable role in pneumatic valves.
The author interviewed Weidun VTON Of Inlet pneumatic valve The engineer of
1、 Function and use of imported pneumatic valve accessories
Single electric solenoid valve: the valve is opened or closed when power is supplied, and closed or opened when power is cut off ( Explosion proof type available ) 。
Dual electric control solenoid valve: the valve opens when one coil is powered on and closes when the other coil is powered on, with memory function ( Explosion proof type available ) 。
Limit switch annunciator: remote transmission of valve switch position signal ( Explosion proof type available ) 。
Electrical positioning equipment: according to the electrical signal ( standard 4-20mA) Control of medium quality of valve by the size of ( Explosion proof type available ) 。
Pneumatic positioning equipment: according to the air pressure signal ( mark 0.02-0.1MPa) The size of the valve on the medium quality control.
Electrical converter: convert electrical signal into air pressure signal, and use it together with pneumatic positioning equipment ( Explosion proof type available ) 。
Air source treatment triplet: including air pressure reducing valve, filter, oil mist separator, to ensure that the air source is stable, clean and lubricated for moving parts.
Manual operating mechanism: the automatic control can be operated manually under abnormal conditions.
