This high purity two stage regulator is designed for corrosive and non-corrosive gases requiring precise and stable delivery pressure control. These regulators provide constant pressure regardless of inlet pressure fluctuations. This stainless steel regulator offers high corrosion resistance and wetted parts of 316 Stainless Steel and TeflonŽ for high purity applications. This regulator features a unique metal diaphragm seal. Captured vent ports are provided for both stages to allow for venting of hazardous gases in the event of a diaphragm failure. This regulator is designed to withstand internal vacuums during purging operations.

DESIGN FEATURES
  • 316 Stainless steel filtered seat for added gas stream purity, and extended service life.
  • Convoluted stainless steel diaphragm for precise control of pressure.
  • Metal to metal diaphragm seal for maximum leak integrity.
  • Large 2 - 1/2" easy to read single scale gauges.
  • Front bonnet is threaded for front panel mounting.
  • 316 stainless steel bar stock body.
