GB Bellows Globe Valve

Bellows shut-off valves are internally constructed in the form of a bellows, with the lower end of the stainless steel bellows welded to the valve stem to prevent process fluids from leaching the stem. The other end is placed between the valve body and bonnet to form a static seal. Bellows globe valve with double sealing design, when the bellows leakage stem packing will also avoid leakage, bellows welded to the stem, not only to maintain stable operating performance, but also to avoid the stem vibration caused by the vibration of the valve plug. Bellows disconnecting valve is suitable for steam, flammable, explosive, thermal oil, high purity, toxic and other media on the pipeline.

Second, the characteristics of the bellows disconnecting valve is introduced:

1, bellows disconnecting valve product design and reasonable structure, not only good sealing performance and reliable, and beautiful modeling;

2, bellows disconnecting valve sealing surface surfacing Co-based cemented carbide, wear-resistant, corrosion-resistant, anti-friction performance is good, the use of long life;

3, bellows disconnecting valve stem tempering and surface nitriding treatment, good anti-corrosion and anti-friction performance, greatly reducing the loss;

4, right-angle German standard bellows disconnecting valve with double sealing, valve performance is more reliable; national standard carbon steel bellows disconnecting valve, bellows disconnecting valve parameters, wenzhou bellows disconnecting valve instructions

5, bellows disconnecting valve stem lifting position indication, more intuitive;

6, bellows disconnecting valve parts material, flange and butt welding number size can be based on the actual working conditions or user requirements for reasonable selection, to meet the national standards, to meet a variety of engineering needs.

Third, the advantages of the bellows disconnecting valve: when the need to use the bellows disconnecting valve in the horizontal pipeline electric disconnecting valve is a relatively new type of disconnecting valve category, it has its own structure of some of the unique superiority, such as switching frictionless, the seal is not easy to wear and tear, opening and closing torque is small. This can reduce the specifications of the matching actuator.
