Specifications

The Bellofram Type 3210 electro-pneumatic regulators provide a precision pressure output, which is proportional to the user's electrical command signal. The single closed loop controller has a pressure sensor in the manifold block, which will provide accuracy to +/- 0.50% full scale. The reliable twin solenoid valve system requires no air consumption (conserves air - no constant bleed) at steady state output pressure. The CE approved design features a weatherproof housing and can be pipe mounted inline or conveniently on top of a booster relay for higher flows. The model 3210 is not sensitive to mounting orientation.
