The Engineering Behind Voice Coil Actuators in Servo-Pneumatic ValvesLearn how voice-coil force, spool feedback, gas-flow disturbance, and a documented 30 Hz valve example shape servo-pneumatic response, testing, and accuracy.
Proportional Flow Control vs. Proportional Pressure Control ValvesCompare proportional flow and pressure control valves using an SMC 85-to-40 L/min example, feedback architecture, load behavior, and acceptance tests.
How to Tune a PID Loop for a Proportional Valve and Cylinder SystemTune a pneumatic PID loop with 10–90% rise-time traces, anti-windup, derivative filtering, valve-neutral checks, and load-range validation for cylinder motion.
Understanding Hysteresis and Linearity in Proportional Valve SpecificationsCompare proportional-valve hysteresis and linearity using SMC's 0.5% and ±1% FS example, test curves, reference methods, conditions, and clear RFQ checks.
The Impact of Deadband on Proportional Valve Control AccuracyLearn how proportional-valve deadband differs from hysteresis, how a 0.4% model rating affects control, and how to measure and compensate it in practice.
A Technical Guide to Spool Position Feedback in Proportional ValvesUnderstand spool position feedback in proportional valves, including LVDT and Hall sensing, inner-loop limits, data-sheet checks, commissioning, and fault diagnosis.
The Function of Sandwich Plates: Pressure Regulators and Flow ControlsLearn how 5-port pneumatic sandwich plates regulate common or individual ports, meter exhaust flow, preserve manifold compatibility, and verify stack order.
