Stainless Steel Forged Steel Pressure Seal Bonnet Bellows Gate Valve

Full – forged high – temperature high – pressure bellows, globe valve fusion pressure self – sealing valve and bellows valve technical advantages.

The stable performance of self-sealing valve under high temperature and high pressure.The higher the medium pressure, the greater the upward thrust of the middle path, the better the sealing effect of the middle road, and the leakage of the middle road will not occur.And with bellows valves triple seal design (bellows seal, valve stem packing seal and pour stem seal), when corrugated tube densely failure, stem packing also can avoid leakage, even packing leakage, the valve stem fell in a fully open timely replacement of packing also can prevent the leakage, and conform to the international standard of sealing.

ANSI Bellows Seal Bellows globe valve is a new type of globe valve, because this valve is double seal design, so the sealing performance is more reliable than the ordinary globe valve.

UNIQUE corrugated pipe globe valves have the following characteristics:

1. Bellows + packing double seal design: corrugated pipe formed by metal barrier to prevent leakage and packing after the corrugated tube failure can also provide sealing function, applied more safety, energy saving, environmental protection, zero leakage.

2. Disc conical design: when the valve is closed, the tapered sealing surface with “scraping effect” can automatically remove the surface impurities to ensure the disc has a reliable seal and longer service life.

3. Bellows seal: the key part of the bellows seal cut-off valve is the metal bellows, which ensures no leakage of the bellows assembly through the connection between the automatic rolling cover and the stem.

4. All kinds of disc design can be designed according to the requirements of the working conditions, which can be designed for various disc designs such as throttling disc, cut-off check disc, flat soft seal and so on.

5.The new handwheel design is more ergonomic.Product application: steam system, heating oil system, cold water system, etc.
