RTK, a CIRCOR International brand specializing in the design and manufacture of control valves and actuators, introduced the REflex Quick Change Seat Control Valve with REact 30 DC-PoP smart actuator, a flexible all-in-one solution for noise reduction and high pressure drop applications. The REflex QCS Control Valve assembles and disassembles in four quick steps without the need for special tools. Tool-free seat exchange allows for quick adaptation to changing conditions. Featuring optimized high-capacity flow paths and interchangeable trim, the two-way REflex QCS Control Valve supports a variety of media and meets NACE standards for use with abrasive liquids and gasses. It is highly customizable for lower flow and higher pressure drop and available in one- or two-stages, as well as a range of sizes, pressure classes, and end connections types. All REflex valves are available either as ANSI or DIN. These valves excel at control and shut-off of liquids and gases, feedwater boiler filling, superheater start-up, and as relief valves.
The REact 30 DC-PoP actuator equips the REflex QCS Control Valve with innovative smart valve technology to ensure system safety in any situation. When operating in normal conditions, the REact 30 DC-PoP’s intelligent, high-efficiency, brushless DC motor can be adjusted to four separate speeds for energy savings and precision. These systems are also easily interconnected for remote monitoring. Then, in case of power failure, the two system-saving functions—the standard Emergency Closing Unit and a Power off Positioning module—smoothly opens or closes to a predefined safety end position. Automatic return to closed loop control is possible without any external components or wiring, ensuring that the valve resumes normal duties as soon as the plant returns to normal operations.
