采用平衡型阀芯设计，式阀腔上方压力与阀前保持一致，提高流体稳定性，启闭力矩小，适合高压差、大流量工况。

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.
