Engineered from virgin PTFE, injection molded PFA and other engineered thermoplastics, Furon 2 inch HGVM valves offer the highest Cv flow factors of any fluoropolymer valve of its size. Furon HGVM high purity valves offer a reliable means of handling large volumes of aggressive or ultrapure chemistries. 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. This manually-actuated version features a large, ergonomically designed adjustment knob for ease of operation while wearing cleanroom gloves.
