A versatile computer-controlled valve
We have developed a computer-controlled valve based on the popular Nupro B-4HK bellows valve. The valve is actuated by a stepper motor. A modification to the Nupro valve necessary to achieve reproducible performance in setting the flow rate is described, and performance data on the coefficient of fl...

| Zusammenfassung: | We have developed a computer-controlled valve based on the popular Nupro B-4HK bellows valve. The valve is actuated by a stepper motor. A modification to the Nupro valve necessary to achieve reproducible performance in setting the flow rate is described, and performance data on the coefficient of flow is presented. These valves have been cycled thousands of times without difficulties. |
