Here's a step-by-step approach to efficiently designing systems that work right the first time. Pneumatic sequence controllers provide step-by-step system operation. Sequence valves and other components mount to the manifold subplates. A selector valve gives the option of one-cycle operation...

Off-the-shelf electrodeposited-nickel bellows replace costly and stroke-limited custom bellows in gas-turbine fuel-control valves. In-line, microprocessor-controlled valves from Continental Controls Corp. work with PLCs to match fuel flow to turbine rpm and load. Valves use two oil-filled...

* Work Devices - the actual work effects are obtained by supplying air to actuators and other air-operated devices. At the end of the actuator's work cycle, the "used" air is returned to the atmosphere, either directly through a control valve or through devices designed to reduce exhaust noise or remove...

...efficient option. Such controls use a sensor to gauge engine coolant temperature and tell a fan to run only long enough to cool the engine. Otherwise the fan freewheels. Large, over-the-road rigs have used pneumatic on-off fan clutches for years. The units need compressed air to work and tend...

...for instance, use a filament-wound fiberglass epoxy resin matrix with a woven bearing element of Teflon and polyester. The bearings can be made in numerous shapes and inexpensively customized to work in a wide range of conditions, including harsh industrial environments. For example, pneumatic...

Raising the efficiency of compressed-air systems could save thousands of dollars yearly. Save air with a regulator added to a valve bank. Placing FRL elements on scheduled maintenance intervals reduces pressure drop and lets air flow. Compressed air is considered the "fourth utility " in many...
