Netherlocks Developed Partial Stroke Device for the World’s Most Compact Actuator.
19 September 2003
Netherlocks developed Partial Stroke device for the world’s most compact actuator.
ATC (Actuator Technology Company) is manufacturer of world’s most compact actuator, which is accomplished by a very revolutionary design. ATC offers a patented and certified concept with following features:
- Output torque that meets the valve torque with a minimum of energy loss,
- Sub-sea to 100m,
- Closed and protected spring cartridge,
- Position indication,
- Material on request,
- Considerably smaller dimensions than typical scotch yoke type actuators,
- Etc.
In order to operate this unique actuator ATC is also able to supply custom made power-packs fully to the client specification.
In extension to the many services that ATC brings already, they were looking for a proven partial stroking mechanism, which should be in accordance to the IEC 61508 & 61511.
Since Netherlocks is well known for their FAITH (Fail Action Integrated Test Handling) systems ATC choose this company to design a partial stroking device that could be integrated in a unique way. Two systems are at the moment available; the mechanical- and the diagnostic type. The last mentioned is unique since it doesn’t test the actuator & valve only, but also the critical control components. Every test is archived and shows immediately possible damages in the actuator, valve or control components.
