WJ41H bellows globe valve refers to a valve that uses a bellows as the stem sealing element. It is made of high quality austenitic stainless steel with good plasticity, high elastic limit, tensile strength and fatigue strength, good welding performance and stable elastic performance Bellows, good steel used on the blade, absolutely guarantee zero leakage of the valve. In the heat conduction pipeline, it can save a lot of hot oil, prevent environmental pollution and ensure the safety of the workshop. WJ41H German standard bellows globe valve is suitable for flammable, explosive, highly toxic, toxic fluid, high temperature heat transfer oil, liquid ammonia and other media with nominal pressure PN1.6 ~ 16MPa and working temperature -29 ℃ ～ 425 ℃.
Valve use and characteristics:
WJ41H bellows globe valve is widely used in petrochemical, chemical fiber textile, plastic paper, power steel, printing and dyeing rubber, natural gas and other gas systems. Its performance is safe and reliable, and it is widely used in industrial fluids such as ethylene glycol. WJ41H bellows globe valve adopts the design of bellows seal, which completely eliminates the shortcomings of ordinary valve stem packing seals, such as aging, and easy to leak, not only improves the use of energy efficiency, increases the safety of production equipment, reduces maintenance costs and frequent Maintenance also provides a clean and safe working environment.
1. The product structure is reasonable, the seal is reliable, and the double sturdy and durable bellows seal design (corrugated pipe + packing) ensures zero leakage of the valve stem. No fluid loss, reducing energy loss and improving plant equipment safety. And meet international sealing standards;
2. The sealing surface is surfacing welded with Co-based hard alloy, which has good wear resistance, corrosion resistance, good anti-friction performance and long service life;
3. The valve stem is quenched and tempered and the surface is nitrided, which has good anti-corrosion and anti-friction performance; the valve stem position indication is more intuitive;
4. Double sealing, more reliable performance, more intuitive indication of valve stem lifting position;
5. Parts materials, flanges and butt welding dimensions can be reasonably selected according to actual working conditions or user requirements to meet various engineering needs.
