GF Piping offers 604/605 pneumatically actuated dosing valve

Oct. 5, 2017 – GF Piping Systems has introduced a corrosion-resistant pneumatic diaphragm valve that promises to provide a new, long lasting solution for not only highly corrosive dosing applications, but also open/close applications.

The Type 604/605 Pneumatically Actuated Dosing Valve is designed and tested to surpass two million life cycles, says the company. Boasting a lower price point than other similar models on the market, the 1/2-inch (d20) size 604/605 valve is available in body materials PVC, CPVC, PROGEF Standard PP, and SYGEF Standard PVDF with a range of end connections and custom assemblies. The valve is pressure rated at 90 psi unidirectional with operating temperatures ranging from -4 to 284 degrees F, depending on body material. According to the company, GF’s threaded bonnet design eliminates both the need for metallic body bolts and retorquing after hot line shutdowns, adding that oversized pneumatic ports decrease cycle time to maintain accurate dosing with minimal overrun.
 
“The 604/605 dosing valve is a totally different type of valve for us,” says Jeffrey Sixsmith, GF Piping Systems product manager for valves and actuation. “While its primary intention is for dosing applications where it can withstand corrosion, its compact size and low cost make it an attractive alternative to more expensive conventional diaphragm valves for open/close operations.”
