3.3. EXHAUST COMPENSATION VALVE (MCP 125)
The valve is located in the final duct that serves the exhaust compensation unit (in the kitchen). It is
therefore in Ø125 mm. This product is specific to DX system.
With its diameter, the compensation exhaust valve can exhaust airflow more than 230 m
3
/h (at 60
Pa).
The valve can be positioned in any direction, the maximum length being 232 mm. However,
attention must be paid to the direction of the airflow in the valve: an arrow marked on the
valve indicates the correct position.
The pressure within the exhaust ductwork is measure in the compensation valve, just after the
damper. This allows to measure the pressure at the same level than the extract units. This measure
takes into account the pressure drops through filters and exhaust ductwork. It ensures at the extract
units the require pressure needed for a perfect running with a very high accuracy.
