pneumatic valve component system of each part of function and purpose
Pneumatic actuator: divided into double acting type and single acting type.
Double acting pneumatic actuator: two position control for valve opening and closing.
Single acting pneumatic actuator (spring return type): in case of pneumatic cut-off or failure, the valve will open or close automatically.
Valve: The valve is the control part of the fluid delivery system.
Solenoid valve: it is divided into single electric control solenoid valve and dual electric control solenoid valve
Single electric control solenoid valve: the valve is opened or closed when power is supplied, and closed or opened when power is off.
Double electric control solenoid valve: when one coil is energized, the valve opens, and when the other coil is energized, the valve closes.
Limit switch: it can transmit the signal of valve switch position remotely, including mechanical type, proximity type and inductive type.
Pneumatic electric positioner: adjust and control the medium flow of the valve according to the size of the current signal (standard 4-20mA).
Air source treatment triplet: air pressure reducing valve, filter, oil mist device, which can stabilize and clean the air source and lubricate moving parts.
Manual operating mechanism: manual operation under abnormal automatic control.
Silencer: installed at the exhaust port of solenoid valve to reduce noise.
Quick plug connector: one end is connected to the solenoid valve or actuator, and the other end can be directly inserted into the air pipe.
Air tube: hose, copper tube, stainless steel.
