Reflux Control

The reflux loop is either a flow or temperature controlled loop and is used to adjust the purity of the overhead product. A poorly operating reflux control valve will cause product purities to oscillate, difficult column control, and lost efficiency. 

Spartan’s reflux control solutions provide accurate and reliable control and measurement to increase efficiency and maximize productivity and profit. 

Fisher EZ valves are used for throttling or on-off control of a wide variety of liquids and gases. The single-port, globe-style body design offers quick-change trim and a post-guided, unbalanced valve plug. The EZ valve is used in chemical or hydrocarbon processing applications or wherever control of non-lubricating, viscous, or other hard-to-handle fluids is required.
Vee-Ball™ V300 is a flanged valve for throttling or on-off operation for many different applications in the process industries. The V300 is available in NPS 1 through 16, CL300 (DN 25 through 100, PN 15/40). Trim components are interchangeable between Design V150, V200 and V300.
Fisher’s next generation control valve is a compact state of the art control valve and actuator system designed to control a wide range of processes. Reduced complexity gives fewer spare parts for easier maintenance. The compact design exists in a smaller envelope and is lighter weight with a field reversible actuator.
The FIELDVUE DVC6200 is a digital valve controller capable of operating using 4-20 mA, HART, Fieldbus, or Profibus communication protocols. The basis of its operation is the conversion of a control signal into a pneumatic output controlling valve position.
The 3051S ERS system is a flexible, 2-wire HART architecture that calculates differential pressure (DP) electronically, using two pressure sensors. The pressure sensors are linked together with an electrical cable and synchronized to create a single 3051S ERS System.
