The ARCATORQUE actuator is a spring suspensive actuator for rotary valves. Standard rage is 90°, adjustable at ±3° in the final positions. A reinforced rolling diaphragm guarantees frictionless conversion of pneumatic admission into stroke movement of the actuating spindle. The spindle guiding, ball-and hub bearing are made of maintenance-free PTFE materials and guarantee high precision at conversion of stroke into rotary movement.
