Parker B511BB553C Stacking Solenoid Valve 120V Ac

Product Description

The PARKER B511BB553C is a 4-way, 2-position stacking solenoid valve designed for directional control of compressed air in pneumatic systems. It operates on 120V AC and features a single solenoid with air return actuation, making it a standard choice for machine automation, pneumatic cylinder control, and fluid power circuits. The valve carries a Cv rating of 1.4 and accepts 1/4 inch inlet and outlet connections. It is rated NEMA 4 for use in wash-down or wet-location industrial environments. Licensed HVAC technicians, pipefitters, and industrial maintenance technicians are the typical installers for this type of directional control valve.

This valve is suited for pneumatic control applications in light industrial, commercial, and process automation settings. Its stacking body-ported design allows for modular manifold assembly when multiple valve stations are required. The air return mechanism eliminates the need for a second solenoid coil, simplifying wiring in applications where spring or air return is acceptable. Operating temperature range spans 5 degrees F to 120 degrees F, making it appropriate for most indoor and sheltered industrial environments. The 1/4 inch port sizing fits standard compressed air distribution lines common in production and HVAC control panels.

Key Features

• 4-way, 2-position directional control with single solenoid and air return
• Cv rating of 1.4 for efficient airflow in 1/4 inch port pneumatic circuits
• 120V AC coil voltage for direct connection to standard control circuits
• NEMA 4 enclosure rating for use in wet or wash-down locations
• Maximum working pressure of 145 psi (10.00 bar)
• Stacking body-ported design supports modular manifold configurations

Compatibility

Designed as an OEM-style directional control valve for 4-way pneumatic circuits using 1/4 inch ported connections and 120V AC control voltage in stacking manifold or inline installations.

Installation Notes

Installation should be performed by a qualified industrial maintenance technician or pipefitter familiar with pneumatic directional control valves. De-energize the control circuit and depressurize the pneumatic system fully before servicing or replacing this valve. Verify supply voltage matches the 120V AC coil rating before energizing. Consult applicable NFPA and local compressed air system codes for manifold assembly and pressure relief requirements.
