The double block and bleed structure are used to block upstream and downstream synchronously, and each surface has two kinds of seals style, soft seal and hard seal. The soft seal guarantees the valves's zero leakage which the hard seal protects the soft seal and with the fireproof function.

The seal parts abrasion means the life of avalve, as there's no abrasion for the guide way valve during the slips turning, so the life only depends on the rubber's aging speed, so it prolongs the using life.
