1、法兰截止阀结构紧凑，造型美观，性能优良。阀瓣与阀杆采用活络连接结构，启闭灵活，阀杆设计了倒密封副，提高阀门的使用寿命和密封性能。

The flange stop valves are compact, beautiful and excellent. The disc and stem are connected to the valve stem, and the valve stem is designed with an inverted seal to improve the service life and sealing performance of the valve.

2、法兰截止阀密封副材料配对合理，阀瓣在运行时与阀座的摩擦力很小，使用寿命长。

The flanged cut-off valve is matched by the sealing side of the valve. The disc has a small friction force against the seat and the service life is long.

3、法兰截止阀阀杆表面经氮化处理，具有良好的抗腐蚀性、抗摩擦性。填料采用四氟材料，密封可靠，操作灵活，启闭力矩小。

The surface of flange globe valve stem is treated with nitride, which has good corrosion resistance and frictional resistance. The packing USES four fluorine material, the sealing is reliable, the operation is flexible, the opening torque is small.

4、法兰截止阀可选用各种配管法兰标准及法兰密封面型式，还可选用手动、蜗轮传动、电动、气动、液动等各种驱动方式，满足用户不同需求。

4, flange globe valve can choose all kinds of standard piping flange and flange sealing surface pattern, also can choose manual, worm gear, electric, pneumatic, hydraulic, etc all kinds of driving mode, satisfy different customers' needs.
