Unbalanced multi-stage step-down control valve is suitable for the field with large pressure difference and easy to produce flashing and cavitation. According to the working conditions, a plurality of different porous cage sleeves are designed Internals, so that the fluid starts from the first cage that contacts, consumes the internal energy of the high-speed medium, and reduces the flow rate.
