outlet pressure at a fixed ratio through mechanical proportional adjustment.<br \/>\n2.Its core function is to stabilize the output pressure, ensure that the downstream pipeline or equipment operates within a safe pressure range<br \/>\n3.Achieve dynamic pressure balance without external control<br \/>\n4.Pressure sensing\uff1aOutlet pressure is transmitted to the diaphragm\/piston upper chamber through the feedback pipeline.<br \/>\n5.The diaphragm is acted upon by the combined effect of outlet pressure and spring force.<br \/>\n6.Dynamic balance\uff1aWhen 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.<br \/>\n7.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.<br \/>\n8.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.<br \/>\n9.Automatic pressure stabilization\uff1aThe valve disc position is automatically adjusted with the inlet pressure fluctuation to maintain the outlet pressure stable<\/p>\n<h2>FEATURE<\/h2>\n<p>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.<br \/>\n2.Simple structure\uff1aNo external energy or complex control device, relying on pure mechanical adjustment, high reliability.<br \/>\n3.Maintenance-free design\uff1aNo electronic components, strong pollution resistance, suitable for media with poor water quality (such as fire water systems).<br \/>\n4.Wide adaptability\uff1aSupports liquid and gas media, common ratio range 1.5:1 to 4:1, maximum working pressure up to PN25.<\/p>\n<h2>\u0420\u0410\u0411\u041e\u0427\u0415\u0415
