Needle valve
The NV-01 series of ultra-pure PFA needle valves are specially developed to handle corrosive chemical liquids and gases with high purity. The design adopts injection-molded high-purity PFA valve body and valve stem as the only wet components. The sealing area of the valve stem is precisely processed to ensure a smooth and consistent hand-turning feel. The polytetrafluoroethylene bushing ensures a reliable seal between the valve stem and the valve body. The specially designed PFA valve stem stopper prevents the valve stem from loosening from the valve body during use. If you need sizes other than 1/4" and 3/8", please contact our company directly for inquiries.
