Proportion-Air, Inc. is a manufacturer of electronic air pressure regulators and air flow control valves. Founded in 1985 by corporate President Daniel E. Cook Proportion-Air offers a large family of electronic air pressure regulators and air flow control valves that allow you to select the best product to match your exact application requirements
The QL3 allows high volumes of air to move quickly and precisely at pressures up to 150 psig using proportional solenoid valves with a unique analog PID circuit. Ideal for use with flow meters, it provides high resolution and smooth pressure control at high and low flow rates and avoids the “steps” prevalent in most feed and bleed I/P’s. The output is proportional to the electrical input or command signal.
Proportion-Air is pleased to introduce electro-pneumatic pressure control and flow control valves equipped with the Modbus Serial bus. The serial communications capability is now available on the popular QBT, QPV, and QB3 series of pressure control valves which operate as Modbus slaves.
Proportion-Air accepts both Visa and MasterCard. Call us today.
