The main structural features of the internal thread bellows globe valve:
1, the product structure is reasonable, reliable sealing, excellent performance, handsome in appearance;
2, sealing surface surfacing Co hard alloy, wear resistance, corrosion resistance, good abrasion resistance, long life ;
3, stem quenching and nitriding surface treatment, good corrosion and abrasion resistance;
4, double sealing, more reliable performance;
5, stem lift position instructions more intuitive.
Advantages of the internal thread bellows globe valve:
1, double seal design (bellows + packing) If the bellows failure, stem packing will also avoid leakage, and in line with international standards for sealing.
2, safety and environmental protection, no fluid loss, reduce energy losses, improve plant equipment safety.
3, long service life, reduce the number of maintenance, reduce operating costs.
4, rugged bellows seal design to ensure zero stem leakage, providing maintenance-free conditions.
