Often, control applications will demand precise pressure regulation of air or gases at high pressures with low flows. Proportion-Air developed the QBS high pressure valve for this reason.

• Full vacuum to 500 PSI (34.47 Bar)
• Wide range of analog and digital command signal options
• Stainless steel, aluminum or nickel-plated brass bodies available

This device uses two high pressure solenoid valves and a stainless steel sensor to control the pressure with an internal control board at an output accuracy of ±0.5%. The QBS is perfect for low flow (<1 SCFM) applications under static/deadheaded conditions. If higher flow rates are required, we can often mount the QB2S on a volume booster to meet those needs.
