316L Stainless steel mini tube end needle valve

This miniature needle valve features a compact design, small size, and light weight, making it ideal for space-constrained piping systems or equipment requiring high integration. Its pipe-end interface structure facilitates easy installation, allowing for connection via threads or ferrules without welding. The core valve core and seat fit precisely, and fine adjustments can be made by rotating the handwheel. The flow rate curve is smooth, enabling wide-range flow control from microliters per minute to tens of liters per minute. It can withstand pressures up to approximately 6000 psi (approximately 41.4 MPa) and has a leakage rate of less than 1 × 10⁻⁶ mL/s He, meeting the requirements of systems with high sealing requirements.
