SMC promises an end to compressed air waste
Many general machinery manufacturers are ignoring a common operational problem that costs users money and wastes compressed air – but the means of solving it is easily available, according to experts at global pneumatics specialist SMC.
A simple principle that's often completely overlooked is whether it's really necessary for the return stroke of a pneumatically-operated cylinder to function with the same pressure as the working stroke, the company says. Design engineers at the company found that air consumption can be cut by up to 40% after installing its series ASR and ASQ air-saving valves (pictured) which work by reducing the pressure required to operate the return stroke of a cylinder - which, in turn, cuts operating costs.
The valves are the same size as a conventional flow controller. The ASR pressure valve incorporates a miniature integrated regulator with check valve and speed controller, while the ASQ comprises a quick supply and exhaust valve with speed controller.
