Newly launched Remote Control (RC) Twin Power (TP) actuators are used in offshore and onshore choke valve installations. Available in pneumatic or hydraulic design, with torques up to 800Nm, the RC TP is a step-by-step adjustable actuator with high precision and has 18 or 27 steps per turn. The TP actuator allows field conversion from manual to actuated operation without disassembly of the valve. Remote Control TP actuators are not required to withstand the thrust loads as these loads are contained by the valve bonnet. The TP actuator is provided with a standard RC1990 switch box in EEx dIIC T6/T5/T4 or intrinsically safe design EEx ib IIC T5/T6. Different switches and feed back positions can be offered. The actuator is provided with visual indication, linear or rotating, and graduated in percentage adapted to the valve. An electric or visual indicator is available. The actuator is adaptive from 3 1/2 to 550 valve turns. Solenoid valves, filter regulator, tubing and connectors are offered in stainless steel AISI316 (A4) or according to customer specification.
