Wherever manufacturers require linear actuators in industrial automation, they look for a highly reliable system capable of accurate and fast positioning. However, these are not the only factors central to deciding on the right choice of equipment.
A rodless linear actuator solution that integrates control valves can prove to be more beneficial than having the control valves separate from the actuators. Here are five reasons why:
One of the most obvious advantages of choosing linear actuators with integrated valves is the saving on space. Mounting rails on the sides of the cylinder can enable modular components such as linear guides, brakes, valves and magnetic switches to be fitted to the cylinder itself, solving many installation problems, especially where space is limited.
With directional control valves integrated into the actuator unit, it’s much simpler to connect.
The reduced number of compressed air connections required as a result of the compact design of these actuators means less tubing, less potential for leakage and overall reduced air consumption. Its more rigid design also translates into longer lifespan.
With end caps that can be rotated into a variety of positions, they provide increased flexibility when it comes to mounting and tubing options. Moreover, where valves are built into the end caps, actuation of the rodless cylinder becomes much more direct and dynamic.
When repairs or replacements need to be carried out on the actuators, system downtime is minimized as there are no external valves with external air connections to worry about.
Compare the features of the ORIGA OSP-P range of pneumatic rodless linear actuators. They boast a compact design that is easy to connect and operate. Despite their compact design, their technical performance has not been sacrificed. Available in 25, 32, 40 and 50 mm sizes, the OSP-P rodless linear actuator has built-in 3/2 directional control valves and can be used under high ambient temperatures, in clean rooms, explosive environments and for low/high speed applications.
