Part-turn actuators
The "small" electric part-turn 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 components are made of bronze, all external screws are made of stainless steel. This ensures complete resistance against seawater even over a longer time period.
The SGM actuators are designed for open-close duty and positioning duty (classes A and B) / (short-time duty S2 - 15 min), the SGMR actuators for modulating duty (class C) S4 - 40%.

Part-turn actuators
The "small" electric part-turn actuator range with separate MEC controls.
All parameters are directly set at the MEC controls. 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 components of the actuator are made of bronze, all external screws are made of stainless steel. This ensures complete resistance against seawater even over a longer time period. The housing of MEC controls is made of aluminium provided with AUMA powder coating also achieving a premium corrosion resistance.
The actuators are designed for open-close duty and positioning duty (classes A and B) / (short-time duty S2 - 15 min), the variant for modulating duty (class C) S4 - 40%.

Industrial Ethernet
HART makes use of the known 4 – 20 mA standard signal for analogue data transmission. HART communication is modulated as additional signal to the analogue signal. Advantages: The digital HART signal can be transmitted simultaneously to the digital signal. The existing 4 – 20 mA infrastructure is thus also available for digital communication. Consequently, this allows for reading additional parameters and diagnostic data from field devices.
HART is based on the host-field device principle. The optional multidrop HART topology essentially complies with the line structures of fieldbus systems. In most cases, the conventional 4 – 20 mA point-to-point communication is used.

Part-turn gearboxes
In spite of the high degrees of automation, there are still valves requiring manual operation. This is in particular the case if the respective valves are only rarely operated for opening or closing.
The GHE type range with the housing made of bronze is suitable for operating part-turn valves (butterfly valves and ball valves), as predominantly deployed in shipbuilding.

Multi-turn gearboxes
GP multi-turn gearboxes in combination with SA multi-turn actuators act as multi-turn actuators with higher output torques.
They are typically used with stem gate and wedge gate valves. Due to their compact design, these gearboxes can also be used in confined spaces.
