Bellows cut-off valve, also known as bellows sealing valve. The use of bellows seal design, relying on stainless steel bellows for the body's core sealing materials, graphite seal for the auxiliary seal, effectively eliminates the valve STEM filler seal aging fast, easy to leak the problem, so the bellows cut-off valve does not exist packing pressing problem, switch easy, For large-caliber cut-off valves, a balance valve chamber or an auxiliary transmission mechanism can be used. Not only improves energy efficiency, but also enhances the safety of production equipment, reduces maintenance costs and maintenance costs, and provides a clean and safe atmosphere for the working environment.

Bellows cut-off valve has the following characteristics:

1, Valve switch when the handwheel does not rise and fall, it can be used in small space occasions.

2, valve core, valve seat is sealed with a cone, to prevent leakage.

3, sealing surface surfacing co-base cemented carbide wear resistance, corrosion resistance, long life.

4, valve switch, valve stem lift position display, simple operation.

5, stainless steel bellows and graphite filler double seal, reliable performance. If the bellows unfortunately fail, the filler seal on the stem can provide two times for sealing to prevent leakage.
