SPARE COIL FOR 4V&3V

A Pneumatic Spare Coil for 4V & 3V Series Solenoid Valves is the electromagnetic component that provides the electrical control for these common pneumatic directional control valves.It's the heart of the solenoid operator, converting an electrical signal into the mechanical force needed to shift the valve's spool (the internal part that directs airflow).Key Features & FunctionFunction: The coil, when energized with the specified voltage (e.g., $24\text{V DC}$, $110\text{V AC}$, $220\text{V AC}$), generates a magnetic field. This field pulls a plunger (armature), which then controls the pilot air to shift the main spool, thereby changing the direction of the air flowing to the pneumatic actuator.Compatibility: It is specifically designed as a replaceable part for the popular 3V (3-way) and 4V (5-way) series of pilot-operated solenoid valves used for controlling pneumatic cylinders and other devices.Insulation & Protection: These coils typically feature a durable, often epoxy-molded or encapsulated, casing with an IP rating (e.g., IP65) for protection against dust and water jets, and use a high-temperature Insulation Class (e.g., F Class) for reliability in industrial environments.
