ITT Grinnell Dia-Flo R2774 CF3M ½” Diaphragm Valve – Stainless Steel Body, Flanged Ends, Manual Handwheel, Designed for Corrosive and Sanitary Applications

ITT Grinnell Dia-Flo R2774 CF3M ½” Diaphragm Valve – Stainless Steel Body, Flanged Ends, Manual Handwheel, Designed for Corrosive and Sanitary Applications

Condition: Used. Unit shows normal cosmetic wear from service. Stainless steel housing intact.
The ITT Grinnell Dia-Flo R2774 CF3M ½” diaphragm valve is a compact, corrosion-resistant valve used in high-purity, chemical, and sanitary processing environments. This valve features a CF3M stainless steel body (also known as 316L stainless with extra low carbon), offering superior resistance to corrosive chemicals and making it ideal for pharmaceutical, food-grade, and chemical processing applications.
The manual handwheel actuator provides precise flow control and reliable shutoff via a top-entry bonnet design. As with all Dia-Flo® series diaphragm valves, the internal diaphragm (typically PTFE, EPDM, or a composite) forms a leak-proof seal between the actuator and the media, preventing contamination and ensuring clean operation. The R2774 model number corresponds to a diaphragm valve with weir-type body and flanged connections, rated for service in demanding process systems.
