Proportional
Flow Control
VP60
5/3 open loop proportional flow control valve. Direct
operated spool with microprocessor driven position
controll. Closed loop on request. Excellent regulation of
the centre position (very small overlap). Optional Software
VP-Tool allows Enduser modification of Parameters
like center position, valve function, set point.

82880
Motorized 2/2 open or closed loop proportional valve
controlling the flow of media via rotating ceramic discs,
suitable for use with fluids or gases down to vacuum
pressure. The motor can be either DC synchronous or stepper
designs, driving the disc through a low-backlash gear.
A new stepper motor 9668 that fits with the 82880 IMI
Buschjost range and which is used in the majority of cases, was
entirely redeveloped and comes with a wealth of new features.
> Motor is factory-calibrated to improve
the control characteristics
> It detects "stiction" and adjusts torque
automatically up to the 2.5 fold
> Position feedback can be set to 0-20mA or 4-20mA
> Supply voltage is 24 Volts
