Pressure reducing regulators reduce a higher supply pressure at the inlet down to a regulated lower pressure at the outlet (downstream). Back pressure regulators work the opposite way. They regulate the inlet (upstream) pressure by opening up only as much as necessary to hold back the desired pressure at the inlet (upstream). APPLICATION HIGHLIGHTS There are hundreds of potential applications for the unique capabilities of an Equilibar® Back Pressure Regulator (BPR). Equilibar back pressure regulators are designed for use in liquid, gas, and mixed phase spanning from ultra low flow rates to extreme high pressures. By using unique combinations of diaphragm and O-ring materials, Equilibar back pressure regulators perform brilliantly in the harshest environments that include high temperature and aggressive chemicals. Equilibar BD Series is specifically designed for applications where larger sized valves are required. Following are some examples. Pump Pressure Control The Equilibar BD regulator can precisely control the discharge pressure of virtually any type of pump by installing the regulator in a return loop back to the supply reservoir. This pressure bypass setup ensures consistent pressure as the application demand rises and falls. Equilibar customers have used this setup for spray systems, bottle filling and many other “ondemand” type applications that have variable flow. A manual pilot setpoint regulator may be used for simplicity or an electro-pneumatic pilot regulator may be used to computer automate the system.
