Multi-turn actuators, Compact actuators

SVC/SVCR

The "small" electric globe valve actuator range with integral controls. All parameters are directly set at the actuator. The controls contain switchgear, power supply unit, interface to the DCS. The controls automatically switch the actuator off once the valve end position is reached, motor overheating is detected or a torque overload has occurred.

All housing parts are made of aluminium. For this reason, the actuators are very low in weight.

The SVC actuators are designed for open-close duty and positioning duty (classes A and B) / (short-time duty S2 - 15 min), the SVCR actuators for modulating duty (class C) S4 - 40%.

10 Nm to 100 Nm
