The Valve flap and valve sealing surface precision ground and assembled 100% pressure test, all to achieve zero leakage. As the secondary seal above the bellows still retains the stuffing, but also increase the reliability and security. The high-pressure valve metal bellows are multi-layer structure, hydroforming, to ensure that the on / off life at 10,000 times the maximum pressure of the whole trip.

bellow Globe Valve uses the advantages:

1, dual seal design (bellows fill) if the corrugated tube failure, the stem packing will avoid leakage, and in line with international seal standard.
2, safety and environmental protection, there is no fluid loss, reduce energy losses, improve the safety of plant equipment.
3, long service life, reduce maintenance times and lower operating costs.
4, rugged bellows seal design to ensure zero leakage of the valve stem, to provide maintenance-free conditions.
