Quick Change Seat Control Valve

The valve assembles and disassembles in four quick steps without the need for special tools, accelerating maintenance by up to 85% for efficiency and cost savings. Tool-free seat exchange allows for quick adaptation to changing conditions. Featuring optimized high-capacity flow paths and interchangeable trim, the valve supports a variety of media and meets NACE standards for use with abrasive liquids and gases. The unit is 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. Suggested application include power, process, industrial, chemical, petrochemical, LNG, refrigeration technology, and oil & gas, for control and shut-off of liquids and gases, feedwater boiler filling, superheater start-up, and as relief valves. The actuator equips the valve with smart valve technology to ensure system safety in any situation. Under normal conditions the actuator’s motor can be adjusted to four separate speeds for energy savings and precision. These systems are also easily interconnected for remote monitoring. In case of power failure the two system-saving functions—the standard Emergency Closing Unit and a Power off Positioning module—the valve smoothly opens or closes to a predefines safety end position. Automatic return to closed loop control is possible without any external components or wiring.
