The orifice between valve seat and valve cartridge increases
when the valve is opened by turning the handwheel anti-clockwise. More heating water can flow into the radiator or heat
exchanger and the room temperature rises.
The orifice between valve seat and valve cartridge decreases
when the valve is closed by turning the handwheel clockwise
and the supply of heating water into the radiator or heat
exchanger is throttled. At the right limit stop the valve is closed
except for a possible leakage rate.
