A line of electronic two-way metering needle valves is presented. High
precision linear stepping motors drive the valve spindle.
The resolution of the stepping motor driven needles is 0.0005"/step. Standard
optional 0.000125" /step resolution available. Low differential pressure valves,
may be operated continuously (100% duty cycle). Valves stay in position as
when de-energized.
Advantages over solenoid operated valves include cool operations, i.e. there
are no control operating problems due to coils heating up, extremely fine reso-
lution, very low differential pressures and high operating pressures. Valves are
controllable by TTL compatible logic level and analog 0 to 2.5 Vdc signals.
