Proportion Air Inc. Electric Pneumatic Regulator QBS Series
Electric Air Regulator QBS Series
The QBS series from Proportion Air Inc. utilizes the manufacturer's proprietary closed-loop control technology (patented).
The main unit consists of two solenoid valves, a manifold, a pressure sensor, and an electronic circuit. The feedback signal from the pressure sensor is compared with the command input signal in a closed-loop control circuit, driving the two valves to achieve the desired pressure control. The second loop type further inputs signals from an external pressure sensor to perform precise pressure control.

Company information
Air Water Mechatronics Co., Ltd. ST Division handles excellent measurement/control equipment focused on the most important themes of pressure and flow in the field of measurement and control in the industrial sector. In pressure measurement, as the Japanese distributor for Setra Systems, we have supplied numerous pressure sensors domestically for many years. Setra's pressure sensors are characterized by high precision and sensitivity, and are used in many advanced technologies, including semiconductor manufacturing equipment. Additionally, to accommodate various industrial pressure measurement scenarios, we also handle products from companies such as BD and Honeywell. We manufacture digital pressure gauges that incorporate or externally attach these pressure sensors. Within our company, various pressure standards with traceability to national standards are installed in a strictly air-conditioned calibration inspection room, allowing us to conduct inspections and recalibrations in-house. Regarding flow measurement, we offer unique and high-value-added products for both liquid and gas (mass flow). For liquids, we primarily provide small, cost-effective, and highly accurate turbine flow meters, as well as Coriolis flow meters. We respond to diverse needs with disposable sensors for pharmaceutical and medical manufacturing, as well as certified sensors for food and beverage applications.
