Centralized Vacuum Distribution

  • Schematic showing how a vacuum regulator is used to supply different vacuum pressure to various industrial processes.

Controlling Vacuum Header Pressure For Multiple Users

In industrial settings it is common for a single centralized vacuum distribution header to supply several diverse processes, each with separate vacuum pressure requirements. For example, one piece of equipment may function best with 14 inHg vacuum, while another process requires 20 inHg vacuum.

For this application, a vacuum regulating valve is needed on the processes requiring a lower vacuum pressure than the vacuum supply header.

While vacuum breaking regulators are commonly used on vacuum pumps that supply a single pressure, these VBR’s are not suitable in this multiple user vacuum distribution system because the VBR modifies the system vacuum for the entire header.

In the schematic above, Process C requires a higher vacuum level than A or B. In order to use a shared vacuum supply pump, vacuum regulators would be needed in Process lines A and B to reduce the vacuum to the required level.

Vacuum regulators work by restricting the flow from the pump to the process, and do not let air into the process.

Equilibar EVR Vacuum Regulating Valves comes in sizes 1.5″, 2″, 3″, and 4″ for centralized industrial vacuum distribution applications. Materials available include aluminum, stainless steel, and PVC.

Equilibar Technology: A Good Choice for Complex Level Control

While Equilibar technology is known as the gold standard for back pressure control, its unique qualities offer advantages for complex level control applications as well. Using an Equilibar unit for level control could be a good choice in circumstances where there is a wide range of flow rates, varying flow coefficients, varying downstream pressure or Read More
