Valve INLET P1 ENTERS THE CONTROL ROOM OF THE MAIN VALVE THROUGH THE CATHETER AND NEEDLE VALVE 19 (SEE CONSTRUCTION DRAWING) AND ESTABLISHES DIRECTION
Under the pressure P3. The outlet pressure P2 acts under the diaphragm of pilot valve 13 through the catheter and is opposite to the regulating spring of pilot valve
Resistance. When the outlet pressure P2 exceeds the set value of the pilot valve spring, the pilot valve is closed, and the water excretion in the control room is 0.
When THE VARIABLE PRESSURE P3 REACHES THE MAXIMUM, THE MAIN DISC COMPRESSES THE SEAT, THE REDUCING VALVE CLOSES, AND THE DOWNSTREAM PRESSURE DECREASES. When the export
When the pressure P2 is less than the set value of the pilot valve spring, the pilot valve is opened, and the pressure water in the control room will pass through the pilot valve
9. Discharge to the valve outlet. Due to the small opening of the needle valve, the discharge speed in the control room is greater than the pressure water replenishment speed at the inlet.
Thus, the pressure P3 in the control chamber is reduced, and the inlet pressure P1 under the main valve disc 5 is always applied to support the main valve disc
To open the pressure reducing valve and increase the downstream pressure. In steady regulation, the discharge rate is equal to the rehydration rate,
The main valve port opening is unchanged, and the downstream pressure is stable.

The valve body adopts the whole channel streamline design, fluid resistance is small, flow, sealing effect is good, in the transmission mode adopted the hydraulic operation, that is, the use of water pressure in the pipeline to automatically operate the main valve disc up and down movement, control valve opening, adjust the downstream pressure. Maintain the downstream pressure at the pressure set by the pilot valve spring. When the downstream pressure exceeds the set value, the pressure reducing valve will automatically close to ensure that the outlet pressure is unchanged. The product is the ideal product for domestic water supply, fire water and industrial water supply system
