|Sour Service Capability||Available in configurations that comply with NACE MR0175/ISO 15156 and NACE MR0103.|
|Compact Design||The smaller, lighter design of the DF400 control valve makes them easier to handle than standard globe valves of the same size, and usually half the weight.|
|Field Service Friendly||No special tools are required to inspect or service trim, and the actuator is field reversible without additional parts.|
|Versatile Trim Options||Metal and soft seat trim are available in a wide variety of reduced-port trim options.|
|Industrial High Quality External Coatings||Our standard industrial high quality external coatings provide long lasting resistance to the harshest environments.|
|Emissions Reducing Packing||Standard low-emission packing prevents the loss of process media and helps reduce packing maintenance.|
|Blowout Proof Shaft||DF400 shafts are made with a machined shoulder designed to provide exceptional blowout prevention.|
The Model DF400 (Figure 1) is a heavy-duty eccentric plug control valve (sometimes referred to as a rotary globe valve) combined with a powerful spring-and-diaphragm actuator. This valveactuator combo is used in all kinds of demanding applications, including oil and gas production, chemical process industries and severe service environments.
