Needle Valve
● The NV-01 series ultra-pure PFA needle valves are specifically developed for handling high-purity corrosive chemical liquids and gases.The design utilizes injection-molded high-purity PFA for both valve body and stem as the sole wetted components.The stem sealing zone is precision-machined to ensure smooth and consistent rotation torque.The PTFE ferrule ensures reliable sealing between the valve stem and body.The specially designed PFA stem retainer prevents accidental disengagement of the stem from the valve body during operation.
