Working Principle
when working fine
The high and precision valve core valve seat adopts a linear seal.
When the pipeline is under pressure, the valve seat and valve core is tightly closed, and there is no steam.
When the pressure of the steam system drops to normal pressure, the steam in the equipment cools down, and the valve core opens when a negative pressure is generated and a vacuum state occurs.
The differential pressure at which the valve opens is ４.６ｍｍＨｇ
