Parker B844000XXA Stacking Solenoid Valve 4-way 2 Position

Product Description

The PARKER B844000XXA is a 4-way, 2-position stacking solenoid valve actuated by double air pilot with pilot return. It controls directional airflow in pneumatic circuits by shifting between two flow paths, making it a core component in automated machinery, production equipment, and industrial pneumatic control systems. The valve carries a Cv rating of 7.0 and accepts 3/4-inch ported connections. At 2.5 pounds and 8.62 inches in length, it fits into stacking valve manifold assemblies where compact layout and reliable directional control are required. Installation is typically performed by industrial maintenance technicians or automation specialists familiar with pneumatic circuit design.

This valve is suited for industrial pneumatic applications requiring directional control of actuators, cylinders, or other pneumatic devices. The 4-way, 2-position configuration makes it appropriate for extend-retract cylinder circuits and similar double-acting actuator applications. Its body-ported, stacking design allows it to be mounted in multi-valve manifold assemblies, reducing plumbing complexity in high-density control panels and automated process lines. The pilot-operated actuation means the valve requires a separate pilot air supply to shift positions.

Key Features

• 4-way, body-ported valve design for directional pneumatic circuit control
• Double air pilot actuation with pilot return for reliable shift in both directions
• Cv rating of 7.0 for consistent flow capacity in mid-range pneumatic circuits
• 3/4-inch outlet port size for direct manifold or inline plumbing
• Stacking design simplifies multi-valve manifold assembly and reduces field plumbing
• Compact 8.62-inch body length suited for dense control enclosures

Compatibility

Designed as an OEM-style stacking directional control valve for use in industrial pneumatic manifold systems requiring 4-way, 2-position, double air pilot operation with a 3/4-inch port size.

Installation Notes

Installation should be performed by a qualified industrial maintenance technician or pneumatic systems specialist. Depressurize the pneumatic circuit and isolate the pilot air supply before removing or installing the valve. Verify that pilot air pressure is within the range specified by the system design before commissioning. Refer to applicable pneumatic system drawings and the manufacturer installation sheet for manifold port alignment and fastener requirements.
