RFL type cage-type control valve is a cage-guided, pressure-balanced control valve. Due to the balance holes in the cage, it offers excellent fluid thrust characteristics during opening and closing, allowing stable regulation with minimal operating force. The valve adjusts parameters such as pressure and flow by altering the flow area between the valve plug and cage. The cage-type valve effectively addresses issues such as flash, cavitation corrosion, and vibration under high-pressure and high-pressure differential conditions.
