Parker HA7VXBG0G9A Double Solenoid Valve 3-position

Product Description

The PARKER HA7VXBG0G9A is a double solenoid, 3-position directional control valve with a pressure center open unactuated state. The body is constructed from aluminum with a Buna-N seal, making it suited for pneumatic control circuits where a center-open pressure path is required at rest. Operating at 24 volts DC, this valve meets ISO 15407-2 standards and is supplied without a base, requiring a compatible manifold or sub-base for installation. It is typically installed by industrial maintenance technicians and fluid power specialists working on pneumatic automation systems.

This valve is designed for use in pneumatic directional control applications where a 3-position, double-solenoid configuration is required. The pressure center open design allows system pressure to remain active at the center port when the valve is in its unactuated state, which is common in applications requiring controlled actuator float or pressure holding between cycles. A minimum working pressure of 35 psi is required for proper operation. This valve is sold less base per ISO 15407-2, meaning it must be mounted to a compatible sub-base or manifold assembly.

Key Features

• Double solenoid, 3-position configuration with pressure center open unactuated state
• Aluminum body construction for lightweight, corrosion-resistant service
• Buna-N seal material compatible with standard pneumatic system media
• 24 volts DC coil voltage for integration with common industrial control circuits
• ISO 15407-2 compliant, supplied less base for manifold or sub-base mounting
• Cv factor of 1.1, suitable for moderate flow pneumatic applications

Compatibility

Designed as an ISO 15407-2 compliant valve for use with compatible sub-base or manifold assemblies in industrial pneumatic directional control systems. No specific model compatibility was provided in the product data.

Installation Notes

Installation should be performed by a qualified fluid power technician or industrial maintenance professional. De-energize all electrical circuits and depressurize the pneumatic system fully before beginning any valve work. This valve requires a compatible ISO 15407-2 sub-base or manifold and is not intended for direct inline mounting. Verify coil voltage matches the control circuit supply before energizing, and confirm system operating pressure meets the 35 psi minimum requirement.
