Bellofram Type 3000 Electro-Pneumatic Regulators / Model 3210
Bellofram's Type 3000 Electro-Pneumatic Regulators use innovative dual solenoid
valves which simultaneously push and vent air to achieve remarkable performance through
a wide pressure range.
These Type 3000 E/P Regulators are available in ranges as low as 0-1 psig, vacuum,
and absolute pressure ranges
This page focuses on the Model 3210, which is the base model for low-flow applications.
However, as shown in the table below, this innovative techology is available in a wide
range of flow ranges and digital communication options (including local keypad).

3210 Product Detail:
|
|
The Type 3210 single loop and 3220 double loop
electro-pneumatic servo pressure controllers incorporate two solenoid
valves and an internal pressure sensor for increased sensitivity and
accuracy. With current or voltage signal inputs, the Type 3210/3220
controls an output pressure with an accuracy of ± .5% or better full
scale. A wide range of output pressures available, from 29" Hg vacuum
to 600 psig. With a flow of 1.25 SCFM at 100 psi, the 3210/3220 can be
used alone or in conjunction with a volume booster to achieve flow rates
in excess of 2,000 SCFM. Optional output monitor signals are available.
The double loop (3220) option permits 0-10 VDC feedback from a remote
sensor.
Applications include: Semiconductor, Robotics
Controller, Machine Automation, Tire Manufacturing & Testing, Molding
& Forming Operations and a wide variety of industrial applications.
