DETAILS
Model HP722 is a two-stage cylinder regulator in brass barstock for constant delivery pressure from full to near empty cylinder conditions. The Model HP722 is suitable for high-purity gas applications, research sample systems gases, process analyzer gases, gas chromatography, EPA protocol gases, laser gas systems and emission monitoring systems.
Features
- 1-11/16 in.- 316L stainless steel diaphragm eliminates contamination from diffusion or outgassing
- One-piece encapsulated seat design with 10 micron sintered internal filter to protect the PTFE Teflon® seat from particulate contamination
- External relief valve is standard
- Brass barstock body, bonnet and fittings
- 2 in. Brass barstock dual scale easy-to-read gauges (psi/bar)
- Designed to 1 x 10-9 ccsec. inboard helium leak rate to maintain gas purity levels
- Maximum inlet pressure 3000 PSIG
- Front or back panel mountable
- Conforms to CGA E-4 standard for gas pressure regulators
