Parker HA7VXBG023A Double Solenoid Valve 3-position 120V

Product Description

The PARKER HA7VXBG023A is a double solenoid, 3-position directional control valve with a pressure center open unactuated state. It is designed for pneumatic circuit control applications where a fail-safe center position is required to maintain system pressure when neither solenoid is energized. The valve body is machined aluminum with a Buna-N seal and operates on 120 VAC. With a Cv factor of 1.1 and a minimum working pressure of 35 psi, this valve suits light to medium-duty pneumatic actuator circuits. It conforms to ISO 15407-2 and is supplied less base, meaning a manifold or subplate is required for installation.

This valve is used in industrial and commercial pneumatic control systems where directional control of air to double-acting actuators, cylinders, or other pneumatic devices is needed. The pressure center open configuration allows downstream pressure to be maintained at center position, which is common in clamping, pressing, and positioning applications. It is installed by automation technicians, maintenance mechanics, and pneumatic system integrators working on machine control panels and pneumatic circuits. The ISO 15407-2 footprint ensures compatibility with standard valve manifold bases designed to that specification.

Key Features

• 3-position double solenoid with pressure center open unactuated state for fail-safe system pressure retention
• 120 VAC coil voltage suitable for standard industrial control voltage circuits
• Aluminum body construction for lightweight, corrosion-resistant service
• Buna-N seals rated for general-purpose air and compatible pneumatic media
• ISO 15407-2 compliant footprint for use with standard subplate manifold bases
• Cv factor of 1.1 and minimum working pressure of 35 psi for light to medium-duty pneumatic circuits

Compatibility

Designed for use with ISO 15407-2 compliant valve manifold bases and subplates. The valve is supplied less base and requires a compatible ISO 15407-2 subplate or manifold for installation. No specific system or model compatibility beyond the ISO 15407-2 standard was provided in the product data.

Installation Notes

Installation should be performed by a qualified automation technician or pneumatic systems mechanic. De-energize and exhaust all system pressure before removing or installing the valve. The valve requires a compatible ISO 15407-2 subplate or manifold base and should not be powered without the base properly seated and fastened. Verify that the supply voltage matches the 120 VAC coil rating before energizing the circuit.
