PRODUCT MAIN 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 cone 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.It's specially designed with bellow protector. Protector will protect bellow from the erosion of media and double service life.
5.It can reduce temperature difference and increase resistance of fatigue of bellow assembly in the high temperature working condition.
6.With special design, it will have smaller frictional resistance between stem and packing.
