The Type 7150 is a high precision, multi-stage pressure relay offering fine adjustment and maximum stability under variable operating conditions. The Type 7150 combines the proven and reliable technology of the ControlAir Type 200 with the high forward and reverse flow of the Type 6100, 1:1 Relay Volume Booster. A highly sensitive capsule controls the pilot pressure which offers crisp and accurate adjustment.
Relief capacity up to 80 scfm combined with dynamic sensitivity makes the Type 7150 superior for pneumatic counter balance applications.
