The IS & IC series of heavy duty scotch yoke actuators are designed suitable for general purpose of valves and damper automation and offer a wide range of torques enable to operate ball, butterfly, plug valves, dampers or any device that requires a quarter-turn operation for on-off or modulating service.
IS series is the symmetrical design yoke that produces maximum torque at both ends of the 90º cycle providing travel stops.
IC series is the canted design yoke that max produces torque at either close or open end.
Both series actuators come along with a complete line of controls and monitoring accessories including Manual Handwheel (jackscrew), hydraulic overrides, limit switches, solenoid valves, positioners and other controls accessories.
Its modular design and construction provides maximized convenience during installation, maintenance and storage.
Provided two piston guide (Up & down) bars preventing piston's droop due to abrasion after a long time of use, and engineering Plastic Bush for the pistons with good durability of abrasion and lubricative characteristic enable to keep smooth operation at low pressure as well.
Travel stop/adjustment can be set in the range of -5° ~ +95° of stroke and the stoppers are designed in vertical touch in order to bear big shock.Indicator with pointer & angle meter for easy and convenient use
High quality Back-up Ring prevent-ing any possible leakage and ensure long lifespan.
Surface heat-treated Slide Pin, Slide Bearing, and Yoke Slide provides semi-permanent lifespan with strong durability of abrasion.
Hard anodized Aluminum casting and external epoxy powder coated against severe industrial environment.
In order for direct mounting valve and actuator without separate coupler and bracket, bore diameter for valve shaft is increased, so that it can accept thicker diameter shaft rather than standard. Mounting flange as per ISO5211
