As the fall semester for Purdue Polytechnic Institute rolled to a close earlier in December, students in the school’s capstone programs reached the half-way point on their efforts. Proportion-Air is sponsoring two capstone teams this school year. Both teams visited the company’s Indiana manufacturing facility in the fall semester, learning about manufacturing processes and asking […]

Manufacturing experts seeking precise pressure regulation for high-flow applications need look no further than the Proportion-Air QB3 proportional electro-pneumatic pressure regulator — a single device engineered for accuracy and customizable for an application’s specific needs. The QB3 pressure control valve is a complete electronic pressure regulating package consisting of a pilot unit with two solenoid […]

Engineers and other manufacturing professionals looking for a single device that regulates pressure extremely accurately while handling high flows will find it in the Proportion-Air QB4 electro-pneumatic proportional pressure regulator. The QB4 pressure control valve is a complete electronic pressure regulating package consisting of a pilot unit with two solenoid valves, closed-loop electronic controls and […]

Accurate, repeatable pressure regulation for applications like testing industrial products and processes, running fountains, or controlling the temperature of saturated steam can be easily achieved with the right pressure regulator assembly. A Proportion-Air QBX proportional electro-pneumatic pressure regulator piloting a Burling Valve BD4 pressure reducing regulator is an ideal combination to meet the demands of […]

The new site merges all three of the company’s brands — Proportion-Air, Burling Valve, and Protect-Air USA, into one convenient location online. On-demand educational materials, updated drawings and animations for applications covering more than 20 industries, and…

Manufacturers across all industries seek ways to electrify, digitize, and automate their systems to decrease costs and increase efficiency. Electro-pneumatic pressure regulators and valves enable such efforts while improving pressure and flow rate accuracy. Back in the day, there were only manual pressure regulators that relied on the skill and precision of the human hand. […]

Compressed air is often disregarded as a common utility in factories, but risks are high with pressurized air running through pneumatic hoses. Learn how to use these tools safely. Contributed by Mindy Schoeff, Marketing Communications Manager and Ron Hibbler, Applications Manager, Proportion-Air Compressed air is nearly ubiquitous in factories. It’s part of the power behind everything […]

Both electropneumatic pressure regulators and flow control valves can be utilized in controlling vacuum systems. By using an electropneumatic pressure regulator, the designer develops a system which the suction force of the vacuum cup can be precisely controlled. The function of the electropneumatic flow control remains the same when controlling the flow of air in […]

A simple example of explaining a self-relieving pressure regulator is to imagine having a balloon with two normally closed ends. Call the ends supply and exhaust. Assume the balloon is empty and you ask for more pressure in the balloon. The supply end opens until the balloon pressure equals the requested pressure, then the supply […]
