Parker NV109P-2 Straight Needle Valve 1/8 Inch Nptf Brass

Product Description

The PARKER NV109P-2 is a straight needle valve designed for precise flow control in small-bore piping systems. It features a brass body and brass needle, with 1/8 inch NPTF female pipe connections on both ends. The valve measures 1.35 inches in overall length and 1.35 inches in overall height, making it a compact solution for tight installations. Rated to 150 psi maximum working pressure and capable of handling temperatures from -45 degrees F to 250 degrees F, this valve suits a wide range of fluid and gas service applications. Licensed plumbers, HVAC technicians, and mechanical contractors install this type of valve where accurate throttling control is required in low-volume line runs.

This needle valve is suited for residential and light commercial installations where a small-diameter, female-threaded connection is needed for flow regulation. Typical applications include instrument lines, refrigeration service ports, compressed air circuits, and hydraulic or pneumatic control systems. The NPTF thread form provides a pressure-tight mechanical seal without relying solely on thread sealant. It is installed in straight-line piping runs and is well suited to panel-mounted or inline service positions where space is limited.

Installation Notes

Installation should be performed by a licensed plumber, HVAC technician, or qualified mechanical contractor following applicable IPC and IFGC code requirements. Depressurize and isolate the line completely before removing the existing valve or making any connections. Apply thread sealant or PTFE tape appropriate for the service fluid to the male fitting threads being joined to this valve. Do not overtighten the connections, as brass fittings can crack if excessive torque is applied.
