Advantages

1.Bellow seal element.The key part of bellow sealed globe valves is metal bellow. It is the connection between cover and stem by automatic roll welding. The metal bellow can keep the stem part zero leakage.
2.Benefited from the cone and streamline shape design,the disc has reliable sealing performance and longer service life.
3.Double seal design(bellows+packing).Bellow and packing can protect from leakage and provide excellent sealing performance.
4.Grease nipple. It can directly Lubricate the stem, nut and sleeve.
5.Ergonomic hand wheel. It provide longer service life and easier operation.
