Parker B571BCNXXC Solenoid Valve 3-position 1/4 Inch Port

Product Description

The PARKER B571BCNXXC is a double solenoid, 3-position directional control valve with a center exhaust open unactuated state. Designed for pneumatic systems, it controls airflow direction in automation, fluid power, and process control applications. The valve body is constructed from aluminum and uses a Buna-N seal for reliable performance across a wide operating range. It operates between 30 and 145 psi and carries a Cv factor of 1.4, making it well-suited for moderate-flow pneumatic circuits. Note that solenoid coils are not included with this valve body and must be sourced separately before installation.

This valve is intended for industrial pneumatic applications where a 3-position, center exhaust open configuration is required. Typical uses include actuator control circuits in manufacturing, assembly automation, and process equipment where the valve must vent actuator ports to exhaust when de-energized. The 1/4 inch port size fits standard pneumatic manifold and inline installations. Licensed industrial maintenance technicians, pneumatic system integrators, and automation professionals are the primary installers of this valve type.

Compatibility

Designed as an OEM-style replacement or new-installation directional control valve for industrial pneumatic systems requiring a double solenoid, 3-position, center exhaust open valve with a 1/4 inch port.

Installation Notes

Installation should be performed by a qualified pneumatic systems technician or industrial maintenance professional. Depressurize and de-energize the pneumatic circuit completely before removing or installing the valve. Verify that compatible solenoid coils are sourced and matched to the valve body prior to commissioning. Follow applicable NFPA and local industrial safety codes for pneumatic control system installations.
