Valve Fends Off Corrosion, Lives For Two Million Cycles

Viable for both corrosive dosing and open/close applications, the Type 604/605 pneumatically actuated dosing valve can surpass two million life cycles. In typical chemical dosing applications, using low-cost solenoid valves save money, but they corrode and break down, requiring frequent replacement.  High-end, corrosion resistant solenoid valves for the same application last longer, but are very expensive.  The 604/605 dosing valve solves both of these problems. At a lower price point, it is already corrosion resistant, and with minimal metal parts, it provides a longer, more reliable life span.


The 1/2" (d20) size 604/605 Valve is available in body materials PVC, CPVC, PROGEF Standard PP, and SYGEF Standard PVDF with a wide 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. A unique threaded bonnet design eliminates both the need for metallic body bolts and re-torqueing after hot line shut downs. GF Piping Systems, Irvine, CA. 800-854-4090
