Parker HVN4400-15 4-way Air Valve 0.5 Inch Npt Rotary Lever

Product Description

The PARKER HVN4400-15 is a manually operated 4-way, 3-position directional control air valve designed for pneumatic systems requiring precise flow direction control. It features a rotary lever actuator with detent positioning, which holds the valve in the selected position without requiring continuous operator force. The valve is rated at a Cv of 1.5 and connects via a 0.5 inch NPT port. This type of valve is typically installed by industrial maintenance technicians, HVAC controls specialists, and pneumatic system integrators working on compressed air circuits.

This valve suits compressed air control applications in light industrial, commercial HVAC, and mechanical systems where manual directional control is required. The 4-way configuration supports double-acting cylinder or actuator circuits, allowing the operator to direct airflow to one of two output paths or hold a center condition. The detent mechanism makes it well suited for applications where the valve position must remain fixed between operator adjustments without spring return.

Key Features

• 4-way, 3-position valve design supports double-acting pneumatic actuator circuits
• Rotary lever actuator with detent holds selected position without continuous force
• Cv rating of 1.5 for consistent, measurable flow capacity
• 0.5 inch NPT port connection for standard compressed air plumbing
• Minimum working temperature of 32 degrees F for standard indoor and controlled-environment use
• Compact, single-unit package suitable for panel or inline installation

Compatibility

Designed as an OEM-style manual directional control valve for compressed air systems using 0.5 inch NPT connections and requiring a 4-way, 3-position rotary lever configuration.

Installation Notes

Installation should be performed by a qualified technician familiar with pneumatic circuit design and compressed air safety procedures. Depressurize the air supply and lock out the system before removing or installing any valve. Apply thread sealant appropriate for air service to NPT threads and avoid over-tightening, which can crack valve bodies. Verify port orientation and circuit function before returning the system to service.
