GTL-WJ41H German standard bellows globe valve is suitable for flammable, explosive, highly toxic, toxic fluids, high temperature heat transfer oil, liquid ammonia and other media with nominal pressure PN1. Widely used in: petrochemical, chemical fiber textile, plastic paper, electric power steel, printing and dyeing rubber, natural gas and other gas systems, the performance is safe and reliable, widely used in ethylene glycol and other industrial fluids. The driving methods are manual, gear transmission, electric, pneumatic and so on.
Structural features:
1, The product structure is reasonable, reliable sealing, double strong and durable bellows sealing design (bellows + packing), to ensure the stem of zero leakage. No fluid loss, improve plant equipment safety. And in line with international sealing standards.
2, The sealing surface surfacing Co based hard alloy, wear resistance, corrosion resistance, friction resistance, long service life.
3, Valve stem quenching and tempering and surface nitriding treatment, good corrosion resistance and friction resistance; Valve stem lifting position indication, more intuitive.
