INSTALLATION
MANUAL
The Sentronic
LP
valve operates with pulsed pilot valves which change the pressure in a control chamber.
A downstream flow amplifier (pressure booster) converts the control pressure into an output pressure. The output
pressure is measured by a pressure sensor and fed to the integrated digital control circuit.
Sentronic
LP
is particularly suitable for pressure control procedures where a constant pressure is required with
different flow rates, such as air dosing via nozzles or turbine rotation speed control.
Using the available DaS software (Data Acquisition Software), the valve can be adapted to the application if
necessary.
• The pressure connections and the air vent connections are designed in the same size, which results in short
response times both for increasing the pressure and for reducing the pressure.
• Digital pressure control in a closed circuit: An internal pressure sensor measures the output pressure. The
output pressure is adjusted in real time.
• The control parameters can be changed with the additional DaS software. The variability of the parameters
used by the valve is ensured by the DaS software. This flexibility makes it possible to adapt the valve to a very
wide range of applications and to optimize the response time and the precision of the valve and prevent it from
overshooting.
• After determining the optimum parameters, these can be saved for personal use in a project file, which can be
sent into our Product Support Department for future series production.
