Electro-Pneumatic Regulators

Equilibar is proud to represent the Bellofram Type 3000 line of electro-pneumatic (E/P) regulators.

E/P regulators can be used to control pressure in a process based on an automated signal from a PLC or process computer.

These devices also work very well combined with an Equilibar Back Pressure or Vacuum Regulator to control pressure in a process fluid.

The Model 3510, pictured at right, features a local display and keypad, and is capable of communicating via 4-20 mA current, 0-10 VDC voltage, RS-485, or DeviceNet.
