Non-Rising Stem Needle Valve

NSV Non-Rising Stem Needle Valve

The NSV non-rising stem needle valve is designed for precise flow control in instrument lines, gas systems, and high-pressure applications. The body is forged from ASTM A105 carbon steel, offering high density and strength.

The plug and seat are made of V05 (PTFE) material for zero-leakage sealing. The non-rising stem design keeps the stem stationary during operation, ideal for confined spaces.
