Favorite

The Type 3212 single-loop and 3222 double-loop are non-bleeding electro-pneumatic controller with flows exceeding those of most compact standard industrial electronic regulators or I/P transducers. 

The 3212/3222 offers analog monitoring of the output pressure by a 0-10 VDC signal. Many output pressures are available up to 150 psi. Flows to 50 SCFM are possible from the compact Type 3212/3222 electronic controller with integrated booster relay.

A reliable twin solenoid valve system, with an integral pressure sensor, controls pressures to an accuracy of ±0.5%. Custom output ranges are available.
Features
  • Closed loop technology. 
  • Integrated air volume booster. 
  • Current/voltage command and monitor signals. 
  • Compact unit with flows up to 50 SCFM.
