SPECIFICATIONS

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.
