Structure of traditional air stop valve cannot meet the requirements of hyperpressure air system due to its drawbacks of great close moment, poor sealing reliability, etc. However, a balance valve has obvious advantages of original structure, great maneuverability and high reliability.This paper introduces the structure and principle of the balance stop valve with hyperpressure air, and illustrates its advantages by comparison of open and close force analysis and sealing style between the traditional air stop valve and the balance stop valve with hyperpressure air. It also gives advices for the development of the balance stop valve with hyperpressure air.
