Parker NV312P-4-4 Angled Needle Valve 1/4 in Brass

Product Description

The PARKER NV312P-4-4 is an angled needle valve designed for precise flow control in fluid and pneumatic systems. The valve features a brass body and brass needle, with a Poly-Tite tube fitting on one end and a male NPTF pipe connection on the other. It measures 1.07 inches in overall length and 1.72 inches in overall height, making it a compact solution for tight installations. Rated to 150 psi maximum working pressure and a temperature range of 0 to 250 degrees F, it is suited for a wide range of industrial and HVAC fluid-control applications. Licensed tradespeople and mechanical contractors are the typical installers.

This valve is commonly used in refrigeration, HVAC, compressed air, and light hydraulic systems where a low-profile, angled configuration is needed to manage flow or isolate a line. The 1/4 inch Poly-Tite-to-male-pipe configuration allows direct connection between a 1/4 inch OD tube and a 1/4 inch NPTF threaded port. The angled body style is useful in installations where straight-through valve geometry would create routing difficulties or space conflicts.

Key Features

• Angled body style for flexible routing in tight spaces
• Brass body and brass needle for corrosion resistance in fluid and pneumatic service
• Poly-Tite to male pipe end connection supports 1/4 inch OD tube to 1/4 inch NPTF threaded port
• 150 psi maximum working pressure rating
• Operating temperature range of 0 to 250 degrees F
• Compact overall dimensions: 1.07 inches length, 1.72 inches height

Compatibility

Designed as an OEM-style replacement or direct-install needle valve for systems requiring a 1/4 inch Poly-Tite to 1/4 inch NPTF male pipe angled needle valve with a brass body.

Installation Notes

Installation is typically performed by licensed HVAC technicians, refrigeration mechanics, or licensed plumbers, depending on the system. Shut off system pressure and bleed the line before removing or installing any valve. Apply appropriate thread sealant to NPTF connections per the system manufacturer and applicable plumbing or mechanical codes. Do not exceed the 150 psi working pressure rating or the 250 degrees F maximum temperature limit for the installed system.
