The flow regulator SAS is a pressure independent and monitored volume flow regulator. It is available from 0.16 l/min to 6.3 l/min and designed for pipe fitting.
  
OPERATION MODE:
A measuring orifice fixed in the flow regulator determines the volume flow. A control piston ensures constant pressure difference at the measuring orifice, regardless of the pressure difference of inflow P and outflow A.

The volume flow is mostly pressure and temperature independent. The function is ensured if the pressure difference from P to A is min. 5 bar and the available volume flow is more than 10% than the relevant actual volume flow at the operating viscosity of the oil.

The integrated signal generator reports if the volume flow is lower than max. 20% of the actual volume flow.

If the green LED on the valve glows, volume flow is ok. The red LED reports no or a very low volume flow. A protective diode for the cut-off discharge of inductive loads is integrated.
