Parker HVN4400-10 4-way Manual Air Valve 1.4 Cv Npt

Product Description

The PARKER HVN4400-10 is a manually operated 4-way, 3-position air directional control valve designed for pneumatic systems in industrial and mechanical service environments. It features a rotary lever actuator with detent positioning, meaning the lever stays in place without requiring the operator to hold it. The valve carries a Cv rating of 1.4 and connects via a 3/8 inch NPT threaded port. It is sized for compressed air circuits where manual directional control of actuators, cylinders, or other pneumatic devices is required. Installation and service are typically performed by pipefitters, pneumatic system technicians, or industrial mechanics.

This valve is suited for use in compressed air systems where manual, hands-free valve positioning is needed. The 3-position design allows for neutral, extend, and retract functions typical of double-acting cylinder control circuits. Its compact form factor fits into panel-mount or inline configurations in light industrial, HVAC mechanical room, and process automation applications. The 3/8 inch NPT outlet is compatible with standard pneumatic tubing fittings and manifold assemblies commonly found in commercial and industrial installations. Minimum rated working temperature is 32 degrees F.

Key Features

• 4-way, 3-position rotary lever design provides directional control for double-acting pneumatic actuators
• Lever detent actuation holds selected position without continuous operator input
• 1.4 Cv flow rating supports moderate-flow compressed air circuits
• 3/8 inch NPT threaded outlet for standard pneumatic connections
• Minimum working temperature of 32 degrees F suitable for indoor and conditioned-space installations
• Compact valve body fits inline or panel-mount pneumatic assemblies

Compatibility

Designed as an OEM-style replacement or direct addition for pneumatic control circuits requiring a 4-way, 3-position manually operated air valve with 3/8 inch NPT porting.

Installation Notes

Installation should be performed by a qualified pipefitter or pneumatic systems technician. Depressurize and lock out the compressed air supply before removing or installing this valve. Apply thread sealant appropriate for pneumatic service to NPT connections and verify all fittings are secure before returning the system to pressure. Confirm directional port orientation matches the existing circuit schematic before commissioning.
