WJ41H American Standard bellows valve

American Standard bellows valve features: 1, dual seal design (bellow + packing) if the bellows failure, stem packing will prevent leakage and comply with international seal standard 2, no fluid loss, reduce energy loss and improve Safety factory equipment 3, long service life, reduce maintenance times and lower operating costs 4, durable bellows seal design to ensure zero leakage of the valve stem, provide maintenance of conditions 5, gas medium seat with PTFE soft sealing material to improve sealing of the valve 6, high temperature ≤425 ℃ hard seat with cone seal. Achieve zero leakage airtight performance Key Specifications / Special Features: bellows sealed globe valve is I plant the introduction of foreign advanced technology, the use of foreign metal bellows seal technology manufacturing, high-performance elastic metal bellows, expansion particularly long fatigue life. Bellows sealed stop valve with bellows seal design, completely eliminate the shortcomings of ordinary valve stem packing seal aging fast easy to leak, not only to improve the use of energy efficiency and increase production equipment safety, reduce maintenance costs and frequent maintenance also provides a clean and safe working environment. The advantages of using a dual seal design (bellow + packing) if the bellows failure, will prevent the stem packing; external leakage, and sealed in accordance with international standards; there is no fluid loss, reduce energy loss and improve plant safety equipment; long life, reduce maintenance times and lower operating costs; Rugged bellows seal design to ensure zero leakage of the valve stem, provide conditions for maintenance of the structural characteristics of the product: German standard bellows closing valves are suitable for nominal pressure PN1.6-4.0MPa, work the temperature of the oil pipeline, chemical, pharmaceutical, fertilizer, power industry and other conditions of -20 ℃ -350 ℃ cut off or connected piping media. The main structure features: 1, reasonable structure, reliable sealing, excellent performance, attractive appearance; 2, sealing surface Co alloy, wear, corrosion, anti-friction performance is good, long life; 3, the stem quenched and the nitrogen treatment, with good corrosion and anti-friction properties; 4, double seal, more reliable performance; 5, more intuitive stem down position indication; 6, part material, flange and butt size according to actual working conditions or user requirements reasonable matching, to meet various project needs. Clear performance when you need to use in horizontal pipe bellows valve electric shut-off valve is a relatively new type of valve type, it has its own unique structure some advantages, such as switches without friction, seal easy to wear, small hoist torque . This reduces the actuator with the specifications. With multi-turn actuators can be realized on media regulation and tight cut. Widely used in [wiki] oil [/ wiki], [wiki] chemical [/ wiki], urban drainage and other demanding cutting conditions, you must ensure the installation in horizontal pipe corrugated bellows valve according to the angle specified by the manufacturer pipe valve, or in the process of equipment operation, diaphragm emptied encounter some problems can not be completely discharge valve in the media. However, different types of diaphragm, bellows globe valves from different manufacturers, different nominal flow diaphragm valve installation angle is different, and often to the design and manufacture of sterile process equipment has brought a lot of trouble. In the bellows valve T type structure, this empty body problem is even more evident. Compared with bellows valve, Vesta bellows valve is not such a problem, regardless of Vesta bellows valve body is what form of structure, process equipment load operation will not be a "dead" to ensure strict to cut the pipe. And, it can be installed in the piping system of sterile process equipment, in accordance with different installation methods. In pharmaceutical manufacturing, sterile process equipment by a number of horizontal pipes and vertical piping components in pharmaceutical equipment design, because the pipeline location and technical reasons, it must be installed using this bellows globe valve in a specific location. For example, if you install the bellows globe valve in a vertical pipe, a 90 ° Curved shall be via a connection in the same horizontal plane. The T-shaped structure of production costs and high diaphragm, different body structure compared to the shape of the diaphragm, bellows valves in the size and shape is connected to the pipe installation advantages. Since the two types of cut-off valve of different construction types, therefore, in the early stages of aseptic process equipment design, you must select which type of shut-off valves should be used in all parts. In the pharmaceutical, food and biotechnology sector has a large number of output devices valves required to be sterilized. The large valves, for example Stericom series, in which required to be sterilized almost useless. Because, in these process equipment, requiring fewer transport medium quality, for less traffic, it is almost invariably choose the diaphragm. The new bellows valve has a smaller size, can be equipped with different pipe diameters, in this respect more advantages than the diaphragm. Comparison of equipment utilization as user devices within the entire life cycle of the equipment as much as possible the use of equipment for production, that is to say: the utilization of equipment should be as high as possible. And maintenance of equipment, said equipment had to stop production, but also to put some equipment maintenance costs. Bellows valves generally wear and tear; bellows valve, the valve in the event of wear, after a certain time you must replace the bellows, the bellows length of life depends on the respective production process. On the one hand, process equipment corrosion in circulating medium, temperature, pipe cleaning and disinfection, the working pressure and flow, and other process equipment operating parameters affect the membrane life; on the other hand diaphragm shutoff valve opening and closing the deformation of the diaphragm an important factor in determining the life of the diaphragm.
