Line Pressure Regulator – HP 304

HORNUNG GMBH

High precision pressure reduction for high-purity gases, gas mixtures, and liquids
Suitable for gases with purity up to 6.0 and high safety requirements
Optional rear pressure gauge (Hinterdruckmanometer)
Available in different flow ranges: 0.1-1.0 bar, 0.1-1.7 bar, 0.2-3.0 bar

The HP 304 is a single-stage pressure regulator designed for the pressure reduction of high-purity gases, gas mixtures, and liquids. It is suitable for applications requiring high purity up to 6.0, safety, and tightness. The regulator is equipped with a PCTFE seat seal, Hastelloy membrane, and offers a leak rate of 10⁻⁸ mbar l/s. It features a high level of pressure regulation accuracy in the range of 0.1 to 3 bar and is available with an optional backpressure manometer. The HP 304 is certified to ISO 9001:2015 and ISO 14001:2015 standards, ensuring precision and quality.

Use Cases
