California-based GF Piping Systems has introduced a corrosion-resistant pneumatic diaphragm valve that is designed to provide a new, long lasting solution for highly corrosive dosing applications and open/close applications. The Type 604/605 Pneumatically Actuated Dosing Valve is designed and tested to surpass two million life cycles.
The 1/2” (d20) size 604/605 valve is available in body materials PVC, CPVC, PROGEF Standard PP and SYGEF Standard PVDF with a variety of end connections and custom assemblies. The valve is pressure rated at 90 psi unidirectional with operating temperatures ranging from -4 to 284°F, depending on body material.
GF’s unique threaded bonnet design aims to eliminate both the need for metallic body bolts and retorquing after hot line shut downs. Oversized pneumatic ports aim to decrease cycle time to maintain accurate dosing with minimal overrun.
