Parker B874BCNXXA Solenoid Valve 3/4 Inch 3-position

Product Description

The PARKER B874BCNXXA is a double solenoid, 3-position directional control valve designed for pneumatic systems requiring a center exhaust open configuration. The valve body is constructed from aluminum with a Buna-N seal, offering resistance to common pneumatic system fluids and lubricants. With a 3/4 inch port size and a Cv factor of 7.0, this valve supports substantial flow rates in mid-range industrial and commercial pneumatic circuits. It is rated for working pressures between 45 psi and 145 psi and a maximum operating temperature of 120 degrees F. Note that solenoid coils are not included with this valve body and must be sourced separately. Licensed industrial mechanics and pneumatic system technicians are the primary installers.

This valve is suited for use in pneumatic automation systems, actuator control circuits, and industrial machinery where a 3-position directional valve with center exhaust open is required. The valveless coil design allows flexibility in coil selection to match the control voltage of the specific system. Applications typically include factory automation, material handling equipment, and process control systems that use compressed air as the working medium.

Key Features

• Double solenoid, 3-position configuration with center exhaust open unactuated state
• 3/4 inch port size with a Cv factor of 7.0 for high flow capacity
• Aluminum body construction for lightweight durability
• Buna-N seals compatible with standard pneumatic system lubricants
• Operating pressure range: 45 psi to 145 psi
• Valveless coil design — coils ordered separately to match system voltage requirements

Compatibility

Designed as an OEM-style directional control valve for pneumatic systems requiring a 3/4 inch port, 3-position, center exhaust open configuration. Verify coil voltage and electrical connector compatibility before ordering solenoid coils separately.

Installation Notes

Installation should be performed by a qualified pneumatic systems technician. Depressurize and lock out the pneumatic supply before removing or installing any valve. Solenoid coils are not included and must be selected and installed to match the control circuit voltage. Verify all port connections and fitting threads before returning the system to service.
