Adjustment of Proportional Control Valve Characteristics via Pressure Compensation Using Flow Forces
Publikováno v:
Energies, Vol 17, Iss 7, p 1546 (2024)
This article concerns flow analysis through a multi-section proportional control valve. In valves of this type, the flow rate is adjusted through an electromagnet current. However, for a fixed control signal value, the flow rate changes as the pressu
