Kind of bellows valve stem threads are divided by location externally threaded style, thread ceremony. Divided by the flow of media bellows valve with straight, DC type and angle type. Shutoff valve seal form by points, packing bellows sealed globe valves and globe valve. Bellows valve installation and maintenance should note the following: a cut-off valve hand wheels, handles the operation can be mounted in any position on the pipeline. 2, hand wheels, handles and Wei mechanism does not allow for lifting with. 3, the flow of media should be consistent with the direction of the arrow body. Bellows valve for nominal pressure PN1.6 ~ 16MPa, working temperature petroleum, chemical, pharmaceutical, fertilizer, power industry -29 ~ 350 ℃ the other conditions of the pipeline WZ41H bellows valve supplier, or turn off line media. The main features of the national standard bellows valve: Products reasonable structure, reliable sealing, excellent performance, attractive appearance; sealing surface Co based alloy, wear, corrosion, anti-friction performance is good, long life; stem quenched and surface nitriding treatment, good corrosion and anti-friction properties; WZ41H double seal bellows valve manufacturers, more reliable performance; stem down position indication, more intuitive; parts materials and flanges, butt weld end dimension may be based on the actual working conditions or user requirements reasonable matching, to meet various project needs.
