RTK, a Circor International brand and leader in design and manufacturing of control valves and actuators, has introduced the RTKREflex Quick Change control valve with balanced trim. This compensates for high differential pressures within the trim, and allows high pressure drops to be controlled.
The balanced trim also saves costs by eliminating the need for a large actuator, and reducing lead time. An RTK actuator, pneumatic or electric, can now be used in combination with RTK valves. The actuator is also available with the new RTK REact EQ-PoP from 6 kN to 10kN(2250 lb/f), which offers two system-saving features. It features a standard, as well as an Emergency Closing Unit and a PoP-module (Emergency power supply) that allows the actuator to reach a predefined safety end position if power is lost, to ensure system safety in any situation. With compatible QC designs, it is now easy to convert existing valves to a balanced trim if parameters have changed.
