• The basics of pneumatic control valves
  Directional valves such as Parker Hannifin's B3G-Series threeway (left) and four-way valves are often used to control pneumatic operations. Directional-control valves are vital in any pneumatic circuit, directing or blocking airflow to control the speed or sequence of operations. One method...
• Did You Know that Valves are the Heart of Your System?
  , (such as a UCP-522) a high spring range such as 8-13# is best so you have better return force. The drawback is that you must have a pneumatic air system. The pneumatic actuator also invites less precise control due to back pressure from the water causing a spring range shift, thus changing the control pressure...
• Hydraulic Pumps
  The power source is the key element in a fluid-power system. In a pneumatic system the power source is an air compressor, while in fluid-power systems it is a pump. These normally are driven by an electric motor or internal combustion engine. Various concepts are applied to convert the mechanical...
• Steppers go shaftless
  serves in a semiconductor wafer lift mechanism where it replaces a less-accurate pneumatic actuator. The same motor and drive system is being used as a precision linear actuator to drive a syringe for fluid dispensing in the semiconductor industry. The new setup significantly improves the linearity...
• May the force loop be with you
  control. The force is created by applying pressure to a working gas or fluid in a hydraulic or pneumatic cylinder. A piston then converts the pressure to a force applied to the load. Another open-loop method uses permanent-magnet motors. An electrical current is applied to the motor windings...
• Hannover Fair Focuses on Energy Efficiency
  ., will introduce PumpDrive, a speed control for centrifugal pumps. This demand-dependent system reportedly produces energy savings of up to 60%. Bosch Rexroth, Hoffman Estates, Ill., will take the wraps off a smart variable-speed pump drive that matches flow to demand, cutting motor/pump speed when...
• Special ICs
  Manufacturers have also developed special-purpose ICs that handle tasks needed to implement both closed-loop motion control and motor speed control. Presently, three chips are available for closed-loop control, one for multiaxis contouring, and a few others for motor speed control...
• Making Air Systems Clean & Quiet
  savings from lubricated air exceed the cost of installing and maintaining the lubricators. * Pneumatic-system exhaust air can be noisy and contain oil mist. * OSHA frowns on in-plant noise and air pollutants. * Coalescing mufflers provide a simple, inexpensive fix. Park Hannifin, Filtration...
• Motion Reference Guide: Software Keeps Linear-Stage Integration Straight
  into a protracted and painstaking trial-and-error process. The amount of time and effort needed to set up, configure, and commission these devices led many designers to alternative options, such as pneumatic actuators or timing-belt drives, when a linear motor or ball screw would have been the better...
• Straighten up and go linear
  -motion-control application faced three imperfect options: traditional electric motors or hydraulic or pneumatic cylinders. Hydraulic actuators have many inherent problems, such as high cost, leakage, and inefficiency. Pneumatics are less expensive but require a fair amount of maintenance, and have...
