Parker B512BB549C 4-way Stacking Solenoid Valve

Product Description

The PARKER B512BB549C is a 4-way, 2-position stacking solenoid valve with a single solenoid actuator and spring return mechanism. It controls directional flow in pneumatic circuits and is designed for stacking manifold configurations. The valve operates on 24 VDC and carries a Cv rating of 1.4, making it suitable for moderate-flow pneumatic control applications. With a NEMA 4 enclosure rating, it holds up in wet or wash-down environments. Inlet and outlet port sizes are both 3/8 inch. Licensed HVAC technicians, industrial maintenance techs, and fluid power specialists are the typical installers of this valve type.

This valve is suited for use in pneumatic directional-control systems found in industrial automation, process equipment, and HVAC control panels. The body-ported, 4-way design allows it to direct airflow to actuators or cylinders from a single valve station. Its stacking design allows multiple valves to share a common manifold base, reducing plumbing complexity in multi-circuit installations. Operating temperature range runs from 5 degrees F to 120 degrees F, making it appropriate for standard indoor industrial environments and light-duty outdoor enclosure use where temperatures remain within that range.

Key Features

• 4-way, 2-position body-ported valve with single solenoid actuation and spring return
• 24 VDC coil voltage for direct interface with low-voltage control circuits
• Cv rating of 1.4 for consistent, moderate-flow pneumatic performance
• NEMA 4 rated enclosure suitable for wash-down and wet location installations
• 3/8 inch inlet and outlet ports for standard pneumatic line connections
• Stacking manifold-compatible design reduces plumbing in multi-valve installations

Compatibility

Designed as an OEM-style replacement or direct-install component for pneumatic directional-control systems using stacking solenoid valve manifold assemblies.

Installation Notes

Installation should be performed by a qualified fluid power technician or industrial maintenance professional familiar with pneumatic directional-control systems. De-energize and depressurize the pneumatic circuit fully before removing or installing the valve. Verify coil voltage matches the control circuit supply before wiring. Maximum working pressure is 145 psi — do not exceed this rating in the installed system.
