Cam-Act Part-Turn Pneumatic Actuator

Unique Design – General Features And Benefits

• The Cam-Act pneumatic actuator produces a high starting torque in both opening and closing directions, ideal for unseating stuck valves.
• Switch box and positioner mounting on all sizes are according to Namur VDI/VDE 3845.
• Valve mounting on all sizes are according to ISO 5211.
• Standard angle of rotation is 90°.
• Stainless steel output drive as standard with a female double square.
• Permaglide™ bearings on top and bottom of shaft for smooth rotary movement.
• The 90° rotation is produced by a solid stainless steel cam with zero wear resulting in a long life span.
• Pistons are connected with spacer bars resulting in a pure linear movement therefore not requiring secondary wear pads.
• Single directional pressure on the pistons allow the use of U-Seals on the piston, providing substantially higher sealing rate and longer life span.
• Cam and output shaft compartment is pressure-less and therefore the output shaft is not subjected to possible blow-out.
• Fewer pressure compartments require less sealing components.
• Aluminium housing, end caps, pistons, spacer bars and mounting plates are anodised for corrosion resistance.
• The drive shaft, cam, output drive and all fasteners are corrosion resistant stainless steel.
• Air pressure operation from 2 to 10 Bar.
• All actuators are permanently lubricated in the factory.
• Additional corrosion protection and special coatings on request.
• 100% of all actuators are factory pressure tested.
