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 leakage.

when a vacuum occurs 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. Air entering

The differential pressure at which the valve opens is ４.６ｍｍＨｇ
