Description

Pneumatic rack and pinion actuators QUIFER are in the market for more than 40 years. These actuators are popular for their high resistance and durability and, in consequence, the reduction of the maintenance cost in the production lines. For that reason, our actuators are used in the more exigent markets and environments like oil and gas, offshore platforms or vessels. The linking surfaces of the actuators are designed according ISO 5211 and VDI/VDE 3845. Design of the actuator is constructed according ISO9001:2008, IEC 61508:2010, LOM 05ATEX6032and European Pressure Equipments Directive 97/23/EC 3.10 Technical Data • Linking surfaces according ISO 5211 and VDI/VDE 3845 • Air connections according VDI/VDE 3845 • Drive shaft with square ISO 5211 • All components have high resistance to corrosion • All models have a double opening and closing regulation from the outside • Multiple combination springs allow a wide range of torques for one model • All springs have a preloader, increasing safety • All models are easily convertible from spring return to double acting and vice versa Advantages • Inner cylinder has been completely honey treated to obtain 0,3 – 0,4 mic. rugosity • Shaft and pistons are completely machined • Body and shaft completely hard anodized • Shaft has an anti-ejection retaining ring • Double sealing at the top and bottom of the shaft • Large PTFE sliding guide in the pistons • Large thickness of the walls of actuator to increase durability • Electrolytic nickel to the shaft • Travel stop of the actuators located in the axis of the actuator
