ТЕХНИЧЕСКИЕ ХАРАКТЕРИСТИКИ

1.A proportional pressure reducing valve is an automatic valve that reduces the inlet pressure to the outlet pressure at a fixed ratio through mechanical proportional adjustment.
2.Its core function is to stabilize the output pressure, ensure that the downstream pipeline or equipment operates within a safe pressure range
3.Achieve dynamic pressure balance without external control
4.Pressure sensing：Outlet pressure is transmitted to the diaphragm/piston upper chamber through the feedback pipeline.
5.The diaphragm is acted upon by the combined effect of outlet pressure and spring force.
6.Dynamic balance：When outlet pressure increases: the diaphragm moves upward under pressure, pushing the valve disc to move in the closing direction, reducing the medium flow area, and the outlet pressure drops.
7.When outlet pressure decreases: the spring force pushes the diaphragm downward, the valve disc opens to increase the flow area, and the outlet pressure rises.
8.Proportional characteristics: the outlet pressure is always adjusted according to the preset ratio (such as 1/2 of the inlet pressure), regardless of flow changes.
9.Automatic pressure stabilization：The valve disc position is automatically adjusted with the inlet pressure fluctuation to maintain the outlet pressure stable

FEATURE

1.Proportional constant pressure:The outlet pressure is in a fixed ratio with the inlet pressure, which is suitable for scenarios with large inlet pressure fluctuations.
2.Simple structure：No external energy or complex control device, relying on pure mechanical adjustment, high reliability.
3.Maintenance-free design：No electronic components, strong pollution resistance, suitable for media with poor water quality (such as fire water systems).
4.Wide adaptability：Supports liquid and gas media, common ratio range 1.5:1 to 4:1, maximum working pressure up to PN25.
