Corrosion Resistant Dosing Valve

Dec. 5, 2017
GF Piping Systems' dosing valve provides a long lasting solution for highly corrosive and open/close applications.

A corrosion-resistant pneumatic diaphragm valve that provides a long lasting solution for not only highly corrosive dosing applications, but also open/close applications is the Type 604/605 Pneumatically Actuated Dosing Valve.


It is designed and tested to 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 ½ in. (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.


GF's unique threaded bonnet design eliminates both the need for metallic body bolts and retorquing after hot line shut downs. Oversized pneumatic ports decrease cycle time to maintain accurate dosing with minimal overrun. For OEMs constantly challenged with fitting many components into the smallest space possible, the 604/605 has a smaller footprint and lower cost compared to standard pneumatic diaphragm valves.
