Product Features

1、Small volume, light weight, compact structure, easy maintenance.

2、The slow closing device is novel in design, compact and reasonable in structure, stable and reliable in performance, and it is located outside the pipeline, which avoids polluting the medium.

3、Smooth operation, no vibration, no noise.

4、Using double eccentric structure, its structural parameters have been optimized, can effectively reduce the flow resistance and vibration, so as to significantly reduce the destructive impact of water hammer on the pipeline system.

5、To achieve complete sealing, no leakage.

6、good opening and closing characteristics, the valve opening pressure <0.08MPa, open quickly, close the valve using adjustable, fast and slow two-stage closing mode, slow closing time adjustment range, can be applied to different working conditions.

Product Conformity Standard

Flange connection conforms to GB/T 9113-2010, EN 1092-1:2001, DIN 2501, ANSI B16.5, API 605 and other standards.

The structure length conforms to the long series of dimensions of butterfly valve with double flange connection in GB/T 12221-2005 “Structure Length of Metal Valve”.
