Furon Precision Plug Valves offer a means of precisely regulating flow in liquid and gas applications. High purity Precision Plug Valves feature a manual adjustment knob with fine adjustment threads, allowing the user to precisely set the desired flow rate. Constructed from 100% virgin PTFE wetted parts, they are suitable for use with harsh, aggressive, or ultra-pure chemistry, as well as most gases. Our bubble-tight plug design assures no leakage in gas applications. Panel mount feature is standard on all Precision Plug Valves, allowing the user to easily mount the valves on an instrumentation or control panel.
