Extended range proportional flow valve method

A method for operating a proportional flow valve with a pilot valve member over an extended range and at a low flow rate. The pilot valve member may be operated, by varying the frequency or duty cycle or both of the pulse width modulated current applied to the solenoid, without thereby causing the m...

Zusammenfassung:	A method for operating a proportional flow valve with a pilot valve member over an extended range and at a low flow rate. The pilot valve member may be operated, by varying the frequency or duty cycle or both of the pulse width modulated current applied to the solenoid, without thereby causing the main valve member to open.
