Parker 8W-U12LB-G-SS-HT Union Bonnet Needle Valve

Parker 8W-U12LB-G-SS-HT Union Bonnet Needle Valve is a stainless steel needle valve with a union bonnet connection, designed for precise throttling of fluids in piping systems. The 1/2-inch size and union bonnet configuration enable straightforward installation, field maintenance, and reseating without disturbing upstream or downstream connections. Built from stainless steel with the HT designation, this valve is intended for high-temperature environments where reliable, accurate flow control is essential in instrumentation, hydraulic, or process lines. The needle-and-seat design provides incremental adjustments and reliable shut-off, supporting precise calibration and controlled flow in demanding applications.
