Typical Application Line Pressure Regulator BPR-1 : When the system pressure is lower than the set pressure, the diaphragm obstructs the flow by the force of spring. When the system pressure is higher than the set pressure, the diaphragm compresses the inner spring to connect the flow so as to allow the fluid to pass through the regulator to keep the pressure of the Storage Vessel stable.
Typical Application BPR-2 Series Piston Regulator maintain the required pipeline pressure to ensure the Pump to output fluid stably when system pressure fluctuates.
How they work
Regulator equipment is work the opposite way certainly regulate the inlet (upstream) pressure by opening up only as much as necessary to hold back the desired pressure at the inlet (upstream).
