Furon HGVM Pneumatic Valves offer a reliable means of handling large volumes of aggressive or ultrapure chemistries. Engineered from virgin PTFE, injection molded PFA and other engineered thermoplastics, Furon HGVM valves offer the highest Cv flow factors of any fluoropolymer valve of its size. Our patented PTFE rolling diaphragm is ideal for use in high back pressure conditions which are commonly found in Bulk Chemical Delivery Systems. In-line fluid ports and a fully swept internal flow path support maximum flow efficiency. The manually-actuated version features a large, ergonomically designed adjustment knob for ease of operation while wearing cleanroom gloves. Furon HGVM Valves also feature our time-proven O-ring Free Union end connections, simplifying installation and eliminating the potential for elastomeric contamination. As extra protection against chemical leakage, our 2” HGVM Valves incorporate a no “O-Ring” double seal union which provides a secondary sealing surface and locking design feature.
