Parker B773BCNXXA Solenoid Valve 3-position 1/2 Inch Port

Product Description

The PARKER B773BCNXXA is a double solenoid, 3-position directional control valve designed for pneumatic system applications. It features a 1/2 inch port size and a center exhaust open unactuated state, meaning the valve center position vents both actuator ports to exhaust when neither solenoid is energized. The valve body is constructed from aluminum with a Buna-N seal. It operates within a working pressure range of 45 to 145 psi and handles media temperatures up to 120 degrees F. Solenoid coils are not included with this valve body. Licensed HVAC, pneumatic, and industrial service technicians are the typical installers for this type of component.

This valve is suited for industrial and commercial pneumatic control circuits where a 3-position, center exhaust open function is required. Common applications include actuator control, cylinder sequencing, and directional flow control in air-operated systems. The 1/2 inch port size makes it appropriate for mid-flow pneumatic circuits. Because solenoid coils are sold separately, the valve accommodates different coil configurations to match specific system voltage requirements.

Key Features

• 3-position, double solenoid valveless coil design with center exhaust open unactuated state
• 1/2 inch port size for mid-range pneumatic flow circuits
• Cv factor of 5.9 for airflow sizing calculations
• Operating pressure range: 45 to 145 psi
• Aluminum body construction with Buna-N seals for durable, corrosion-resistant service
• Solenoid coils not included, allowing coil selection to match system voltage

Compatibility

Designed as an OEM-style directional control valve for industrial and commercial pneumatic systems requiring a 3-position, center exhaust open, double solenoid valve with a 1/2 inch port.

Installation Notes

Installation should be performed by a qualified pneumatic or industrial controls technician. Depressurize and lock out the pneumatic system before servicing or replacing any valve component. Solenoid coils must be sourced separately and matched to the system supply voltage before energizing. Verify port connections and flow direction against the system schematic prior to returning the circuit to service.
