Atlas Copco Solenoid Valve Replacement – 1089070214

he Atlas Copco 1089070214 Solenoid Valve is a genuine OEM electromagnetic control valve used in oil-injected rotary screw air compressors. It controls the flow of compressed air within the pneumatic control circuit by opening and closing in response to an electrical signal. This valve plays a vital role in operating the compressor’s inlet valve, unloader system, and other pneumatic control functions. It is a normally closed (NC) solenoid valve rated for 120 V AC, 60 Hz.

Working Process

1. When the compressor controller energizes the coil, the solenoid creates a magnetic field.
2. The internal plunger moves, opening the valve and allowing compressed air to pass through the control circuit.
3. The pneumatic signal actuates components such as the inlet valve or unloader valve.
4. When power is removed, the spring returns the plunger to the closed position, stopping airflow and restoring the default control state.
