What's New


ControlAir introduced the Type 7150 Precision Air Relay, a high-precision, multistage pressure relay offering fine adjustment and maximum stability under variable operating conditions. High-resolution output control combined with high-relief capacity make the rely the choice for pneumatic counterbalance applications like articulating arms and balancers. The Type 7150 combines the technology of the ControlAir Type 200 Precision Air Relay with the high forward and reverse flow of the Type 6100, 1:1 Relay Volume Booster. A sensitive capsule controls the pilot pressure, which offers crisp and accurate adjustment. The rely features high-flow capacity allowing flows up to 265 scfm (7,500 NL/min). Relief capacity of up to 80 scfm (2,264 NL/min) is combined with dynamic sensitivity.
