Resolution Air, Ltd. expands its innovative portfolio of patented Proportional Pinch Valves with their IP66 rated HPPV-EN-PS Position Sensor Series. This advanced feature integrates a compact position sensor offering precise linear position feedback for critical fluid handling applications. Replacing traditional home sensors and encoder combinations, this technology provides a streamlined solution with numerous benefits for industries requiring precision, reliability, and continuous position feedback. In addition, this valve series incorporates robust M12A 8 pin connector technology simplifying installation and wiring. As well as providing fluid metering, the HPPV-EN-PS series generates 12x (50 lbs.) the pinch force of a typical solenoid pinch valve.
Control Requirements
The bi-polar stepper motors used in the Resolution Air, Ltd. Proportional Pinch Valves require two input control signals, a step signal and a direction signal.
Step Signal- A pulse width modulated (PWM) signal. Each pulse generates a single step. For the MPPV-Series, a single step equates to 7.5 degrees of motor rotation (15 degrees for the HPPV-Series). Since the motor shaft is coupled to an integral leadscrew, this rotation translates into 0.0005”/step of linear motion.
Direction Signal- A digital binary signal which determines the clockwise/anti clockwise motor rotation. There are two primary methods for generating, sequencing, and amplifying the step and direction signals required for stepper motor control.
PLC Based Control System
Signals generated by a Programmable Logic Controller (PLC) are amplified and sequenced by a Bi-Polar Chopper Driver (DRV-1) to the level required to drive the Proportional Pinch Valve.
Bi-Polar Driver/Controller System
The Step and Direction signals are generated, sequenced, and amplified by a single control device known as a Bi-Polar Driver/Controller.
