Flow Control Valves
Controls actuator speed by regulating the flow entering or leaving it.
What is happening technically?
Basınç kompanzasyonsuz bir kısıcıda debi, basınç farkıyla değişir. Kısma kaybı Δp × Q / 600 kW olarak ısıya dönüşür.
In practice
If speed changes with load, examine the restrictor type and pressure differential together.
