WJ41H American Standard bellows disconnecting valve is suitable for flammable, explosive, toxic, strong permeability, radioactive and precious, high purity media. Its key component metal bellows, the lower end and the stem assembly with automatic roll welding welding, the upper end and the connection plate automatic roll welding welding welding, in the fluid medium and the atmosphere between the formation of a metal barrier, to ensure zero leakage stem.
Product Features
- The valve flap adopts conical design, the sealing surface and the medium become flow line, better sealing performance, longer service life.
- Dual sealing design (bellows + packing) If the bellows fails, the stem packing prevents leakage and complies with international sealing standards.
- The bonnet has its own grease fittings for direct lubrication of the stem, nut and bushing, rather than the traditional lubrication of the threads only.
- Ergonomic design handwheel, longer service life, easy and convenient operation, more safe and reliable.
Application Areas
American Standard bellows disconnecting valve is widely used in petrochemical, chemical fiber and textile, plastic paper, electric power, steel, dyeing and rubber, natural gas and other gases, safe and reliable performance, widely used in glycol and other industrial fluids. The use of bellows seal design, eliminate the ordinary valve stem aging fast easy to leak the shortcomings of the valve, not only improve the use of energy efficiency, increase the safety of production equipment, reduce maintenance and frequent maintenance, but also provide a clean and safe working environment.
