Model PRV44 – Pressure Reducing Valve OPERATION PRV concept is direct action. Inlet pressure comes into the valve and closes it because of the sections difference. When we compress the spring (10) through the regulating screw (9), the stem-seal (11, 17 and 3) opens the valve and allows the regulation. When any downstream valve is closed and flow=0, PRV will absorb the oscillations and keep the outlet pressure according to the regulation. The valve closes when the downstream pressure exceeds the regulating set pressure. It is recommended to leave a space (between 0,5 and 1 meter) until the c heck...
