Dyna-Flo DF400 Eccentric Rotary Plug Valve

Heavy-duty eccentric plug valve with a self-aligning, straight-through path.

The DF400 is a heavy-duty eccentric plug rotary (globe) control valve combined with a low-profile spring-and-diaphragm actuator. A self-aligning eccentric plug with a straight-through flow pattern gives tight shutoff at higher flow capacities in severe service.

ACTS is Dyna-Flo Control Valve Services’s sole agent in Egypt, supplying the DF400 Eccentric Rotary Plug Valve to oil & gas, petrochemical and power generation plants nationwide from our office in Sheikh Zayed City, Giza. Sizing and selection are handled by our own application engineers, with aftermarket support and technical services once the unit is in service.
