Bellows steam globe valve has reasonable structure, reliable sealing, double rugged bellows sealing design (bellows + packing) to ensure zero leakage of the valve stem. No fluid loss, reduce energy loss, improve plant equipment safety, applicable to nominal pressure PN1.6 ~ 16MPa, working temperature-29 ~ 425 ℃ is mainly used for boilers, high temperature steam, petroleum, chemical, pharmaceutical, fertilizer, electric power industry and other working conditions of the pipeline, cutting off or connecting the pipeline medium.

Bellows steam globe valve adopts bellows for sealing, and its important parts are metal-made bellows, the lower end of which is automatically roll-welded and welded to the stem assembly, and the upper end of which is also automatically roll-welded and welded to the connecting cover, thus forming a metal barrier between the fluid medium and the atmosphere and ensuring zero leakage from the stem. Designed with double sealing (bellows + packing), even if the bellows fails, the stem packing prevents leakage and complies with relevant standards. The bonnet is equipped with grease filler holes to provide lubrication for the stem, nut and bushing.

Bellows steam globe valves for high temperature environments have a stem that does not come into contact with the medium during operation, zero leakage from the stem, and good strength and toughness to withstand long term on/off cycling. Bellows steam globe valve adopts plug-shaped valve flap as the opening and closing parts, the shape of the sealing surface is flat or conical surface, the valve flap along the centerline of the fluid for straight-line movement, the friction between the sealing surface in the process of opening and closing is small, durable, moderate opening height, easy to manufacture and maintenance. It is not only suitable for low and medium pressure environment, but also capable of high pressure environment.
