Harris Specialty gas Regulators

Model HPI 904 is a single-stage cylinder regulator available in nickel plated brass (HPI 904) or chrome plated brassl (HPI 904C) barstock. Designed for applications where a slight rise in delivery pressure from full to empty cylinder can be tolerated.

APPLICATIONS:

▪ High purity gas applications for Non Corrosives Gases

▪ Gas chromatography

▪ Calibration gas, Purging, Blanketing

▪ Process analyzer gases

▪ Emission monitoring systems

FEATURES:

▪ Recommended gases purity levels up to grade 5.0 (99.999)

▪ 302 stainless steel diaphragm eliminates contamination from diffusion or outgassing

▪ One piece encapsulated seat design includes a sintered filter to protect the seat from particulate contamination

▪ Capsule seat with KELF-F (CTFE) sealing surface

▪ HPI 904 - Nickel-plated body, bonnet and fittings

▪ HPI 1904C - Chrome plated body, bonnet and fittings

▪ 1x10-8 mbar I/s He inboard helium leak rate to maintain gas purity levels

▪ 5 ports flexible configuration, 2 high pressure and 3 low pressure

▪ 1/8’’ NPT thread on the bonnet venting for safety

▪ Maximum inlet pressure: 300 bar (4350 psig) and 25 bar (362 pisg) for Acetylene AA version

▪ Cleaned for oxygen service
