外部先进导角座阀，溢流口与滑块间
有自调节密封压盖，阀体角座结构可
实现较大流量，特别是与普通截止阀
相比时。
External advanced Angle, especially
compare with the normal globe valves
seat valve, there is adjustment sealing
gland between over flow drain and
slider, body structure can enforce more
flow rate, especially compare with the
normal globe valves.
