Positioner P9
- Product category: Hydraulic products
Actuator with mechanical repositioning of the valve spool
Positioner P9 has a small but extremely important function in Olsbergs control systems.
The positioner consists of a proportional solenoid and hydraulic servo together with a unique, mechanical repositioning of the valve spool. The system ensures spool position in the valve with an accuracy of a few hundredths of a millimetre.
– No impact from flow forces
– Hydraulics/electronics interface
Positioner P9
Positioner P9 has a small but extremely important function in Olsbergs control systems.
The positioner consists of a proportional solenoid and hydraulic servo together with a unique, mechanical repositioning of the spool. The system ensures spool position in the valve with an accuracy of a few hundredths of a millimetre.
No impact from flow forces
Spool position is not affected by flow forces; it is exactly proportional to the pulse width modulated current that is fed to the positioner solenoid.
Hydraulics/electronics interface
Positioner P9 acts as the interface between hydraulics and electronics during remote control.
Current amplifiers – DA modules – are connected to the positioners and convert control data into pulse width modulated current
Voltage: 24 V
Connector: MPM Form A, 2P
Control current: 0-500 mA
Spool stroke: ± 8 mm
