KSYH - KSYHM Series Hydraulic Scotch Yoke Actuators

KSYH/KSYHM SERIES General Description Hydraulic scotch yoke actuators QUIFER are in the market for more than 15 years. These actuators are popular for their high resistance and durability and, in consequence, the reduction of the maintenance cost in the production lines. For that reason, our actuators are used in the more exigent markets and environments like oil and gas, offshore platforms or vessels. Actuators completely designed, machined and tested in our factory of Spain. Raw material origin of European Suppliers. Stock of the key pieces that allow us to give quick delivery time to our...

Technical Data Linking surfaces according ISO 5211 and VDI/VDE 3845 All components have high resistance to corrosion All models have a double opening and closing regulation from the outside Multiple combination spring cartridges and air cylinders that allow a wide range of torques for one model All springs have a preloader, increasing safety All models are easily convertible from spring return to double acting and vice versa Modular contruction allow the pneumatic cylinder and spring catridge to be assembled to either both sides of the central body Spring cartridge welded to ensure safety...

Advantages Inner cylinder has been completely honey treated to obtain 0,3 – 0,4 mic. Rugosity Hard chromed cylinder as standard Piston with larger sliding surface to increase concentrity All bars made of chromed carbon steel All bushings made of bronze Bank of grease in all sliding parts of the actuator Nitrured yoke to increase life and sliding properties Oversided slide and slide block mechanism Special loking device between sliding block and bar 2 Springs for large sizes to avoid buckling Welded spring cartridge Travel stops located in the axial side of the actuator Manual Override: In...
