Feedback

Remote Valve Actuators (RVAs) consisting of a rotary vane actuator and a position sensor are mounted to the accumulator control valves to provide the actuating force required to function the accumulator valves. The RVAs can move the accumulator control valves to either the open or closed position. Position sensors feedback the position of the actuator and identifies if the RVA has been rotated into the bypass position.

The Digital Valve Control module (center) enables users to remotely function accumulator control valves from anywhere on location using inVision Wellsite SIMOPS tablets or from the touch screen on the unit.
