Double Acting & Spring Return
Your solution for automation processes
Features & Benefits
- Compact Design – AVCS rack & pinion pneumatic actuator produces linear torque output in a compact design utilizing the same body and end caps for double-acting and spring-return units.
- Namur Mounting – Namur VDI/VDE 3845 and ISO 5211 dimensions on all sizes. No special blocks are required to mount solenoid valves, limit switches or positioners.
- Degree of Travel – The standard angle of rotation is 90°. Additional travel rotations through 180° are available. For sizes from AV08 through AV66, AVCS actuators feature dual travel stops that provide ± 10° stroke rotation on both the opening and closing phases of the actuator stroke. 110° of travel is a standard 90° actuator!
- Multiple Output Shafts – The female pinion drive is standard with a double-square output drive, and optional with a double-D drive, keyed drive and designs to meet your specific requirements.
- High-Cycle Bearings – Shaft bearings isolate the pinion gear from the housing and support the shaft for high-cycle applications. Many competitive manufacturers do not provide this critical feature.
- Rugged Tooth Design – The pinion teeth are engaged the full length and stroke of the piston. The pinion height allows manual override without needing to remove the indicator.
- High Visibility Position Indication – External open/close indicator as standard, available for all rotations.
- High Cycle-Life Wear Pads – Piston incorporate double wear pads (skates) to separate the rack fom the actuator wall and serve as both guide and wear bearings.
- Safe Pre-Loaded Spring Cartridges – Epoxy-coated special steel springs are pre-loaded with nonmetallic materials. The stainless steel end-cap fasteners are extra long to allow for spring relaxation. All parts are corrosion-resistant.
- Alternative Operating Media – Air pressure operation from 2.8 to 10 Bar (40 to 150 PSI). Water, nitrogen and compatible hydraulic fluids may also be used to power the actuator.
