DF400ASME B16.34Rotary Control Valve & Actuator
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.
Key Features
- Self-aligning eccentric plug, quarter-turn
- Flanged body, RF end connection
- Standard low-emission packing
- Blowout-proof shafts, reduced-port trim, NACE options
Engineering Benefits
Straight-through path maximises capacity and resists plugging
Class IV metal or Class VI PTFE soft seat for tight shutoff
