Type 3211 & Type 3221 Analog Enclosure Regulator

Brand: Marsh Bellofram Group of Companies

Type 3211 single-loop and Type 3221 are double-loop pressure controllers which offer non-bleeding solenoid valve technology with an integral flow booster.

This produces forward flows that are equivalent to standard industrial electronic regulators or I/P converters within a rugged, waterproof enclosure.

The Type 3211/3221 is available in pressure ranges up to 150 psi, with analog output pressure monitoring via 0-10 VDC signal and logic monitor output of solenoid valves.

A built-in air volume booster provides for a forward flow of up to 19 SCFM and a reverse flow (exhaust) of up to 7 SCFM. The double loop (3221) 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 application requirements.
