Proportional Pressure Reducing ValveIt Is A Valve That Automatically Reduces Pipeline Pressure According To A Fixed Pressure Reduction Ratio, Relying On The Ratio Of Inlet And Outlet Area To Achieve Pressure Reduction. It Does Not Require Adjustment, Is Reliable In Stabilizing Pressure, Has A Simple Structure, And Is Widely Used In High-rise Building Water Supply, Fire Protection, Water Supply And Drainage Systems.

Structurally, It Mainly Consists Of A Valve Body, Piston, Seal, And Fixed Proportional Pressure Reducing Component, Without Spring, Diaphragm, Or Adjusting Mechanism. The Fixed Proportional Pressure Reduction Is Achieved By The Difference In Area Between The Two Ends Of The Piston. Common Ratios Include 2:1, 3:1, 4:1, Etc. The Connection Methods Include Flange, Groove, And Thread.

Core Features:

Fixed Proportional Pressure Reduction, With The Outlet Pressure Varying Proportionally With The Inlet Pressure, Ensuring Stability And No Drift;

Simple Structure, No Vulnerable Parts, Extremely Low Failure Rate, Long Service Life;

Installation Direction Is Not Limited, Both Horizontal And Vertical Can Be Installed, Easy To Maintain;

High Flow Rate And Low Resistance, Suitable For High Flow Systems Such As Fire Protection And Water Supply.

Suitable For Pressures Of 1.0/1.6 MPa And Temperatures ≤ 80 ℃, Mainly Used In High-rise Building Partition Water Supply, Fire Main, Pump Room, Municipal Pipeline Network And Other Scenarios That Require Fixed Proportional Pressure Reduction.
