■ Extended Rod Bellows Globe Valve Product Introduction:
The German standard bellows globe valve is suitable for flammable, explosive, highly toxic, toxic fluids, high-temperature heat-conducting oil, liquid ammonia and other media with a nominal pressure of PN1.6 ~ 16MPa and a working temperature of -29 ~ 350 ℃.
Widely used in: petrochemical, chemical fiber textiles, plastics papermaking, power steel, printing and dyeing rubber, natural gas and other gas systems, safe and reliable performance, widely used in industrial fluids such as ethylene glycol. The driving methods are manual, gear transmission, electric, pneumatic and so on.
■ Structural features of extension rod bellows globe valve:
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, 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.
