Information About 8551A018MS
The 8551A018MS is an ASCO Series 551/8551 directional solenoid valve built around a pilot-operated spool mechanism. Its black anodized aluminum body incorporates 1/4-inch NPT connections and a single-solenoid spring-return configuration for controlling pneumatic flow. The valve operates across a 30–150 PSI pressure range and provides a 0.86 Cv flow coefficient for air and inert-gas applications. An integrated manual operator allows the valve to be mechanically actuated during system setup, testing, or maintenance.
Key Features:
- 4-Way Configuration: Provides 4-way, 2-position directional control for pneumatic circuits.
- Pilot-Operated Spool: Uses pilot pressure to shift the internal spool for controlled flow routing.
- Spring Return: Automatically returns the spool to its normal position when the solenoid is de-energized.
- 120V AC Operation: Configured for standard 120V AC industrial control circuits.
- 1/4-Inch NPT Ports: Provides threaded connections for integration with common pneumatic piping and fittings.
- 0.86 Cv Flow Capacity: Supports controlled airflow for actuator and automation applications.
- Aluminum Body: Black anodized aluminum construction provides a compact and durable valve housing.
- Manual Operator: Integrated manual override enables mechanical valve actuation for testing and service.
The 8551A018MS delivers the reliability and precision required for pneumatic actuator control, directional air switching, and industrial automation systems.
