McCORDSVILLE, Indiana- Proportion-Air is proud to announce its popular QB3 product line has been expanded to include a high pressure and oxygen cleaned version. The QB3H with a slightly enlarged air piloted regulator section can now be used to control pressures from full vacuum to 500 psig. The QB3H is available in two body materials, aluminum and brass, both of which have a Nor-KoteT surface finish. This proprietary phosphorus electroless nickel finish designed for tight tolerance work, has natural surface lubricity and provides excellent corrosion resistance.

The aluminum body is suitable for most inert gasses in typical high pressure applications from 150 to 500psig with an accuracy of +/- 0.5% of full scale. The brass body is designed and cleaned to specifications suitable for use with oxygen service. All units have rugged stainless steel pressure transducers and are NEMA4/IP65 rated.
