套筒導向調節閥
Sleeve guided regulating valve
采用平衡型閥芯設計，式閥腔上方壓力與閥前保持一致，提高流體穩定性，啟閉力矩小，適合高壓差、大流量工況。
Adopting a balanced valve core design, the pressure above the valve chamber is consistent with that in front of the valve, improving fluid stability. The opening and closing torque is small, suitable for high pressure differential and high flow conditions.
