Advantage：

1.Bellow seal element. The key part of bellow sealed globe valves is metal bellow. It is the connection between cover and stem with automatic roll welding. The metal bellow can keep the stem part no leakage.

2.Benefit from the con and streamline shape design, the disc has a reliable seal and longer service life.

3.Double seal design(bellows+packing). Bellow and packing can protect against leakage and provide a excellent seal.

4.Grease nipple. It can direct lubricate the stem, nut and sleeve.

5.Ergonomic hand wheel. It provide longer service life and easier operation.
