Principle of electric bellows globe valve:
The electric bellows globe valve WJ941H / W is suitable for flammable, explosive, highly toxic, toxic fluid, high-temperature heat-conducting oil, liquid ammonia and other media with a nominal pressure of PN1.6 ～ 16MPa and an operating temperature of -29 ～ 350 ℃. The electric bellows globe valve WJ941H / W is equipped with a DZW series multi-turn electric device. It has a small housing, light weight, full functions, and can be used with remote computers. It can also be equipped with electric devices according to user requirements. Electric bellows valves are widely used in petrochemical, chemical fiber textiles, plastic papermaking, power steel, printing and dyeing rubber, natural gas and other gas systems, with safe and reliable performance.
Model of electric bellows globe valve:
Cast steel: WJ941H-16C, WJ941H-25C, WJ941H-40C, WJ941H-64C
Stainless steel: WJ941W-16P, WJ941W-25P, WJ941W-40P, WJ941W-64P
Structural features of electric bellows globe valve WJ941H / W:
1. The product structure is reasonable, the seal is reliable, and the double rugged and durable bellows seal design (corrugated pipe + packing) ensures zero leakage of the valve stem. No fluid loss, improving plant equipment safety. And meet international sealing standards.
2. The sealing surface is welded with Co-based hard alloy, which has good wear resistance, corrosion resistance, friction resistance 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.
