Hydraulic Part-Turn Actuator

We Turn the World for You We put you in the best position We have developed the rotary actuators presented here, which have proven their worth through many years of use, especially for fittings, butterfly valves and ball valves. The highest safety and quality demands as well as longevity and precision are typical features of HKS rotary actuators. Our strengths also include ATEX, DIN standards or special customised solutions. Wherever materials need to be rotated and tilted, precisely accelerated, braked, positioned and held, HKS products are there to help you get the job done – with great...

Typical applications Water works Sewage works Steel constructions for hydraulic engineering Drinking water distribution Chemicals and pharmaceuticals industry HVAC industry Shipbuilding Steel mills Food industry Exploration, offshore facilities Refineries Pipelines Tank farms Geothermal power plants Solar thermal power plants Biogas power plants Power plants (water, coal, gas, oil, atomic)

Functional description The oil pressure which is supplied through connections P1 and P2 causes a rotary movement on the actuator shaft. The linear movement of the piston C is converted into a rotary movement by means of multiple gears. (Sectional representation as from the series SA-H 125) With pressure at P1 the actuator shaft rotates, from the basic position to the left (anti clockwise). Changes in the direction can be especially made to order. Oberfl. Reihe 3 Zul.

Part-Trun actuator spring return AFR Hydraulic / Spring Return You can still obtain our part-turn actuators provided with a spring return. These have been designed for operation in a one-sided hydraulic system. The part-turn actuator normally opens the closed armature by hydraulic pressure and it closes with a spring return. The opposite is achieved with appropriate assembly. Depending on the assembly the ‘open’ or ‘closed’ position can be maintained. Specific customer requirements are taken into account here. up to 38.000 Nm Spring reset single-acting Opening moment up to 38,000 Nm Closing...
