ControlAir LLC, a manufacturer of precision pneumatic and electro-pneumatic control products, announced the introduction of the Type 7150 Precision Air Relay. The Type 7150 is a multi-stage pressure relay offering adjustment and stability under variable operating conditions. Resolution output control combined with relief capacity make the Type 7150 a choice for pneumatic counter balance 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 capsule controls the pilot pressure which offers adjustment. The Type 7150 Precision Air Relay is designed for applications where control, relief, and air flow sensitivity is needed. It’s typically used when increased flow capacity or remote pressure control is required. Applications include volume boosting, roll loading, tension control, cylinder control, pressure control, counter balance, and industrial clutch and brake control.
The Type 7150 features flow capacity allowing flows up to 265 scfm (7,500 Nl/min). Relief capacity up to 80 scfm (2,264 NL/min) combined with sensitivity makes the Type 7150 suitable for pneumatic counter balance applications. Control sensitivity is less than 1/4″ water column and an isolated control chamber provides performance by preventing hunting and vibration, regardless of supply pressure changes or conditions. The Type 7150 Precision Air Relay can handle 250 psi (17.5 bar) maximum system pressure and positive and negative biasing capability. ControlAir LLC manufactures precision pneumatic and electropneumatic controls. ControlAir’s markets include process control, semiconductor, printing and converting presses, diagnostic and surgical medical equipment, robotics, quality control, automotive, analyzers, compressors, pumps and paint equipment.
