Bellows sealed globe valve, the key components - metal bellows, the lower end of the valve stem assembly with automatic welding, welding the upper end of the automatic welding plate, forming a metal barrier between the fluid medium and the atmosphere to ensure that the stem Zero leakage. Valve and valve body sealing surface after precision grinding, assembled after 100% pressure test, all to zero leakage. As a secondary seal, the stuffing box remains on top of the bellows, increasing reliability and safety. High-pressure valve metal bellows are multi-layer structure, through the hydroforming, can guarantee the maximum pressure 10000 times the entire trip on / off life. Advantages: 1, double seal design (bellows + packing) If the bellows failure, stem packing will also avoid leakage, and in line with international standards of 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. Use: Suitable for thermal oil, toxic, flammable, highly permeable, pollute the environment, with radioactive fluid medium pipeline for the cut-off valve, can also be used for regulation, is to create a leak-free factory quality products. The valve casting all cast precision.
