ROSS Controls is famous for its wide variety of pneumatic valves. But what may not be so well known is the science behind the valves.Why are valve systems used? What kinds of systems exist? What principles must we be aware of when working with valves? To answer these questions and. Ross Controls...

proportional to the control signal as long as pressure drop across the valve is constant. Global competition ensures that plant operators face the neverending task of making equipment more productive. This often demands higher speed and precision from their motion-control systems. But in the case...

proportional solenoid valves (rather than the normally closed digital solenoid valve) to create a linear curve of pressure versus time as the cuff is deflated. High-speed digital solenoid valves can be pulse-width modulated during cuff deflation to yield results comparable to those achieved...

Also, if the press’s motor is not producing sufficient RPMs, a drop in pressure could occur. Users should be tuned into various processes on their hydraulic presses to ensure good operations. For example, the valve shifts should be smooth from one speed change to the next - operators should... feature proportional, integral, and derivative (PID) control. While PID loop closure is adequate for static or low-frequency tests, high-performance tests often require special control algorithms to achieve greater accuracy.
