Metso`s Neles series VC actuators are exclusively developed for linear valves. The VC double acting cylinder type actuators are designed for use in both modulating control and on-off service. They provide heavy duty and reliable operation and are well suited for many different kind of applications. The high performance internal coating resists wear and corrosion and the replaceable inner parts guarantee a long life cycle.

When “stay put” failure mode is required, a double acting actuator with lock up valve is the correct choice. If another failure mode is required, a double acting actuator with transfer valve and a volume tank should be selected. The series VC pneumatic cylinder actuators offers a built-in volume chamber or independent volume tank to provide failure in either the open or closed position. The built-in volume chamber provides minimum one time stroking when the instrument air fails.
