Parker B753BCNXXA Double Solenoid Valve 3-position 1/2 in

Product Description

The PARKER B753BCNXXA is a double solenoid, 3-position directional control valve designed for pneumatic or fluid control systems. In its unactuated state, all ports are blocked, which holds actuator position when neither solenoid is energized. The valve body is constructed from aluminum and uses a Buna-N seal for compatibility with a wide range of media. It operates across a working pressure range of 45 to 145 psi and has a Cv factor of 5.9, making it suitable for moderate-flow industrial and mechanical applications. Solenoid coils are not included and must be sourced and installed separately. This valve is typically installed by industrial maintenance technicians, automation specialists, or licensed mechanical contractors.

This valve is well-suited for use in pneumatic actuator circuits, fluid power systems, and process control applications where mid-position port blocking is required. The all-ports-blocked center condition prevents unintended actuator movement during de-energized states, making it appropriate for safety-critical hold positions in automated machinery, HVAC damper control, and similar systems requiring defined fail states. The 1/2 inch port size accommodates medium-flow circuit requirements in both light industrial and commercial environments.

Key Features

• 3-position, double solenoid configuration with all-ports-blocked unactuated state
• 1/2 inch port size with a Cv factor of 5.9 for moderate flow capacity
• Operating pressure range: 45 to 145 psi
• Aluminum body construction for lightweight durability
• Buna-N seals for broad media compatibility
• Valveless coil design — solenoid coils ordered and installed separately

Compatibility

Designed as an OEM-style directional control valve for pneumatic and fluid power circuits requiring a 3-position, all-ports-blocked center condition with a 1/2 inch port interface.

Installation Notes

Installation should be performed by a qualified industrial maintenance technician or licensed mechanical contractor familiar with fluid power systems. Depressurize the system fully and disconnect all electrical power before removing or installing the valve. Solenoid coils are not included with this valve body and must be selected and installed separately per the coil manufacturer specifications. Verify port connections and pressure ratings are within the 45 to 145 psi operating range before returning the system to service.
