Parker B522BB553C Stacking Solenoid Valve 4-way 120V Ac

Product Description

The PARKER B522BB553C is a stacking solenoid valve designed for directional control of air and compatible gases in pneumatic systems. It operates as a 4-way, 2-position valve with double solenoid actuation and solenoid return, meaning both shift directions are powered electrically rather than relying on a spring. The valve carries a Cv rating of 1.4 and runs on 120V AC power. It features 3/8-inch inlet and outlet ports and is rated NEMA 4 for use in wet or wash-down environments. Licensed HVAC technicians, industrial mechanics, and pneumatic system technicians are the typical installers for this class of valve.

This valve is suited for residential and light commercial pneumatic control applications where a compact, stackable directional control valve is required. Its stacking body-ported design allows multiple valves to be mounted together on a common manifold, reducing plumbing complexity in multi-actuator systems. The 4-way configuration makes it appropriate for double-acting cylinder or actuator control. With a working pressure range up to 145 psi and an operating temperature range of 5 degrees F to 120 degrees F, it fits a broad range of indoor and controlled-environment installations.

Key Features

• 4-way, 2-position double solenoid configuration with solenoid return on both sides
• Cv rating of 1.4 for consistent flow performance in pneumatic circuits
• 120V AC coil voltage for direct connection to standard control circuits
• 3/8-inch inlet and 3/8-inch outlet ports for straightforward plumbing integration
• NEMA 4 enclosure rating suitable for wet or splash-prone environments
• Stacking body-ported design compatible with manifold-mount configurations

Compatibility

Designed as an OEM-style replacement or direct-install stacking solenoid valve for pneumatic directional control systems using 3/8-inch ported manifold assemblies and 120V AC control circuits.

Installation Notes

Installation should be performed by a qualified pneumatic systems technician or licensed mechanic familiar with directional control valves and pneumatic circuit design. De-energize all electrical power and depressurize the pneumatic system fully before removing or installing any valve. Verify that the supply voltage matches the 120V AC coil rating before energizing. Follow applicable NEC guidelines for control wiring and ensure the valve body is properly seated and ported before restoring system pressure.
