Spectra Gases

Spectra Gases F7220 series two stage, high purity regulators are designed for corrosive analytical and process applications requiring precise, stable, delivery pressure control. The two stage design yields a delivery pressure change of less than 0.04/100psi inlet chnage. Convoluted stainless steel diaphragms provide excellent regulating characteristics and allow for internal purging. The metal-to-metal diaphragm seal prevents contamination by eliminating the need for a soft seal, and also provides a leak-rate design of less than 2 x 10-8 ccs helium. This minimises cleanup time in purging and yields lower residual contaminant levels.

Features:

  • Stainless steel diaphragms - provides superior leak integrity
  • Bonnet vent ports - allow venting of hazardous gases
  • Standard threaded bonnet - permits panel mounting
  • Diaphragm packless valve - promotes system purity
