Pilot Regulators & Set Point Kits

Supply dome pressure to Equilibar back pressure regulators

Equilibar back pressure regulators are dome loaded. This means they require a 1:1 fluid set point pressure to match the desired inlet pressure. There are many advantages to using our dome loaded design. Some advantages include: Extremely wide range of Cv with a single unit, frictionless operation with no cracking pressure, and no hysteresis as found in traditional spring loaded regulators.

For more information, see how our back pressure regulators work.

Most customers use compressed air or bottled nitrogen to supply the fluid set point signal. Our back pressure regulators can also be controlled by one of our Equilibar electronic set point regulators.

Below you will find some set point kit options for either manual or electronic control.

Equilibar Design Provides Unique High Speed Vacuum Control

Equilibar’s EVR vacuum regulators feature an inherently fast-reacting design that automatically compensates for changes in flow rate.  They offer multiple advantages over traditional vacuum control valves that typically rely on an external control loop and I/P actuator. Unlike traditional valves, the Equilibar vacuum regulator uses a pilot operated design with a flexible diaphragm as the […]
