Parker NV105CA-4 Needle Valve 1/4 in Compression Brass 150 Psi

Product Description

The PARKER NV105CA-4 is a straight needle valve designed to provide precise flow control in low-to-medium pressure fluid and gas systems. The valve features a brass body with compression-to-compression end connections and accepts 1/4-inch outside diameter tubing on both ends. It is rated for a maximum working pressure of 150 psi and operates across a wide temperature range of -45 degrees F to 250 degrees F. Licensed plumbers, HVAC technicians, and refrigeration mechanics install this type of valve in instrumentation lines, refrigerant service circuits, and general-purpose tubing assemblies where repeatable shutoff and metering are required.

This valve is suited for residential and light commercial applications where tubing runs require a reliable, manually adjustable flow-control point. Typical install scenarios include instrument isolation, refrigerant circuit service ports, and hydraulic or pneumatic control lines using 1/4-inch compression fittings. The straight body configuration keeps the flow path direct, reducing pressure drop across the valve seat and simplifying routing in tight mechanical spaces.

Key Features

• Straight valve body keeps flow path direct for minimal pressure drop
• Brass body construction provides corrosion resistance in wet and refrigerant service environments
• Compression x compression end connections for tool-free tubing attachment without flaring
• 150 psi maximum working pressure rated for light commercial and residential service
• Wide operating temperature range from -45 degrees F to 250 degrees F
• 1/4-inch tube outside diameter sizing compatible with standard instrumentation and refrigeration tubing

Compatibility

Designed as an OEM-style replacement or new-installation needle valve for systems using 1/4-inch compression fittings rated up to 150 psi, including refrigeration, HVAC instrumentation, and general-purpose fluid or gas control lines.

Installation Notes

A licensed HVAC technician or plumber should install this valve in accordance with applicable mechanical codes. De-pressurize and evacuate the system fully before removing or installing any valve in a pressurized line. Compression fittings require proper tube preparation including squarely cut, deburred tubing ends to achieve a leak-free seat. Do not overtighten compression nuts, as brass fittings can be damaged by excessive torque.
