Type 3210 & Type 3220 Analog Enclosure Regulator

Brand: Marsh Bellofram Group of Companies

Type 3210 single-loop and Type 3220 double-loop electro-pneumatic servo pressure controllers incorporate two solenoid valves and an internal pressure sensor for increased sensitivity and accuracy, housed within a rugged waterproof enclosure for greater durability and performance.

With current or voltage signal inputs, Types 3210 and 3220 control an output pressure with an accuracy of ±0.5% or better full scale output. A wide range of output pressures are available from 29″ Hg vacuum to 600 psig.

With a flow of 1.25 SCFM at 100 psi, the Types 3210 and 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. Users can order custom configured standard models with such parameters as the number of power loops, logic output, analog control signal, pressure units of measure, supply and output ports and accessories to suit individual applications.
