Pneumatically Operated Diaphragm Valves


• No external metal parts that could corrode and represent a safety hazard with aggressive chemicals
• All wetted parts are molded PFA providing chemical resistance suitable for use in high purity, high corrosive chemical handling applications
• Unique top loading design allows for field repair
• Piston shaft is encapsulated in PFA diaphragm to isolate it from corrosive fluids
• Unique body design allows for 100% cavity drainage to prevent entrapment of fluids
