Wj41 German Standard Bellows Stop Valve Main Applications
The German standard corrugated pipe globe valve is suitable for flammable, explosive, highly toxic, toxic fluids, high-temperature heat transfer oils, liquid ammonia and other media with a nominal pressure of PN1.6~16MPa and a working temperature of -29~350 ℃.
Widely used in other gas systems such as petrochemicals, chemical fiber textiles, plastic papermaking, power steel, printing and dyeing rubber, natural gas, etc., with safe and reliable performance, it is widely used in industrial fluids such as ethylene glycol. The driving methods include manual, gear transmission, electric, pneumatic, etc.
structural characteristics
1. The product structure is reasonable, the sealing is reliable, and the double sturdy and durable corrugated pipe sealing design (corrugated pipe+packing) ensures zero leakage of the valve stem. No fluid loss, improving factory equipment safety. And comply with international sealing standards.
2. Sealing surface welding with Co based hard alloy, wear-resistant, corrosion-resistant, good friction resistance, and long service life
3. The valve stem undergoes quenching and surface nitriding treatment, exhibiting excellent corrosion resistance and friction resistance; Valve stem lifting position indication, more intuitive
