316L Stainless Steel PNV type high-pressure needle valve

This valve features a body, core, and needle rod all precision CNC machined and polished to ensure accurate and controllable flow regulation. The valve rod surface is also nitrided for enhanced strength. The valve seal uses PTFE, PCTFE, or metal sealing rings. The valve body cavity undergoes high-precision polishing, resulting in a smooth flow path that reduces media flow resistance and the risk of sedimentation. The outer surface is also precision polished. The PNV needle valve exhibits excellent pressure resistance in high-pressure systems, typically withstanding 400 to 600 bar. Higher pressure specifications can be customized to meet specific customer requirements, ensuring safe and reliable operation even under extreme conditions. The needle-shaped core design allows for fine-tuning and precise flow control.
