The new Festo range of pneumatic valve actuators includes rotary and linear actuators, ball valves, position sensors and local controllers, suitable for process industries and water/wastewater treatment. This new family of pneumatic components includes 68 single-acting and double-acting quarter-turn actuators for driving butterfly and ball valves, as well as 20 double-acting linear actuators for gate valves and penstocks. The Copar range of quarter-turn actuators offers a choice of 14 different sizes with torque ratings from 8 to 8,800Nm, and each actuator can be set for clockwise or anticlockwise rotation. These actuators are suitable for local, on-the-spot operation, or for automatic operation, and when used in conjunction with a suitable electro-pneumatic controller, the speed can be adjusted. They are suitable for use with the types of process valves used in industrial wastewater treatment plants, which tend to employ valves with diameters of less than 400mm. A new range of position feedback sensors are also available for use with these actuators; housed in IP65-rated enclosures, the sensors can be attached to the actuators.
