Parker B622BB549A Stacking Solenoid Valve 4-way 24VDC

Product Description

The PARKER B622BB549A is a 4-way, 2-position stacking solenoid valve with double solenoid actuation and solenoid return. It is designed for directional control of pneumatic or hydraulic flow in industrial and trade automation systems. The valve delivers a Cv rating of 2.700 and operates on 24 volts DC, making it suitable for integration into low-voltage control circuits. With a maximum working pressure of 145 psi and a NEMA 4 enclosure rating, the B622BB549A is built for demanding service environments. Licensed industrial mechanics, HVAC controls technicians, and fluid power specialists are the primary installers of this valve type.

The B622BB549A is used in applications requiring precise directional control of air or fluid media, including pneumatic actuator circuits, automated process equipment, and industrial control panels. Its stacking design allows multiple valve bodies to be grouped on a common manifold base, reducing plumbing complexity in multi-circuit systems. The valve suits both light industrial and commercial installations where a compact, manifold-mount directional control valve is needed. Operating temperature range is 5 degrees F to 120 degrees F, supporting year-round service in standard indoor and protected outdoor environments.

Key Features

• 4-way, 2-position directional control with double solenoid actuation and solenoid return

• 24 volt DC coil voltage compatible with standard low-voltage control circuits
• Maximum working pressure of 145 psi for reliable service in pressurized systems
• NEMA 4 rated enclosure protects against dust and water ingress
• Stacking body-ported design supports manifold assembly to simplify multi-valve installations
• 3/8 inch inlet and outlet ports for straightforward plumbing connections

Compatibility

Designed as an OEM-style directional control valve for use in stacking manifold pneumatic and fluid power systems requiring a 4-way, 2-position, double solenoid configuration with 3/8 inch porting and 24 volt DC actuation.

Installation Notes

Installation should be performed by a qualified fluid power technician or licensed industrial mechanic familiar with directional control valve systems. De-energize all electrical circuits and depressurize the system fully before servicing or replacing the valve. Verify that supply voltage matches the 24 volt DC coil rating before energizing. Follow applicable NFPA and local codes governing pneumatic and hydraulic control system installation.
