Function of the valve

• The open valve is balanced between the inlet pressure (primary pressure) and the lowest working pressure (secondary pressure). If the working pressure increases above or falls below the desired value, the large surface membrane is pressed up or down against the spring. The valve starts to close or open until the equilibrium state is reached again, that is, regardless of whether the inlet pressure increases or decreases, the working pressure remains constant (if the inlet pressure> working pressure).
