carbon steel bellows globe valve model: wj41h-16c

i. introduction:

carbon steel bellows cut-off valve is also known as bellows sealing shut-off valve, through automatic rolling welding, in the fluid medium and the atmosphere between the formation of a metal barrier to ensure that the stem zero leakage design. gb carbon steel bellows globe valve, bellows globe valve parameters, wenzhou bellows valve

bellows cut valve internal use of the bellows structure, the lower end of the stainless steel bellows welded to the stem, to prevent the process of fluid erosion stem. the other end placed between the valve body and the valve cover to form a static seal. bellows cut-off valve with double seal design, when the bellows leakage valve stem packing will also avoid leakage, bellows welded to the valve stem, not only to maintain a stable operating performance, but also to avoid the valve plug vibration caused by stem vibration. bellows cut-off valve for steam, flammable, explosive, heat transfer oil, high purity, toxic and other media on the pipeline. gb carbon steel bellows globe valve, bellows globe valve parameters, wenzhou bellows valve

second, the bellows valve features:

1, bellows cut valve product design reasonable structure, not only good sealing and reliable performance, and handsome in appearance;

2, the bellows cut-off valve sealing surface welding co-based carbide, wear, corrosion resistance, anti-friction performance is good, the use of long life;

3, bellows valve stem valve quenching and surface nitriding treatment, a good anti-corrosion and anti-friction properties, greatly reduce the loss;

4, right angle german standard bellows valve with double seal, the valve performance is more reliable; gb carbon steel bellows globe valve, bellows globe valve parameters, wenzhou bellows valve

5, bellows globe valve stem position indicator, more intuitive;

6, corrugated pipe cut-off valve parts material, flange and butt welding number size according to the actual conditions or user requirements reasonable matching, to meet national standards to meet the needs of various projects.

third, the advantages of bellows cut-off valve: when the need to use the bellows in the horizontal pipe closing valve electric shut-off valve is a relatively new type of cut-off valve, it has its own structure of some of the unique advantages, such as switch without friction, seal is not easy to wear, opening and closing torque is small. this reduces the size of the actuator.
