Item Details

  • These brass, single-stage, high-purity regulators are recommended for non-corrosive analytical and process applications where precise flow control is not critical. A specially designed, convoluted, stainless steel diaphragm with metal to metal seals provides good regulating performance and maximum purity integrity without the need for a soft seal, which often can be a source of contamination. The CGA-nipple has a special high-purity, non-lubricated check valve incorporated into the nose, and a safety relief valve to protect the internal regulator components. Each regulator is capable of withstanding an internal vacuum and is provided with a diffusion-resistant, diaphragm packless outlet valve to maintain system purity. The optional bonnet vent port (1/8" NPT) allows for the venting of hazardous gases in the event of diaphragm failure.

Features

  • Encapsulated Filter Seat Assembly: For added gas stream purity and extended service life.
  • Convoluted Stainless Steel Diaphragms: Provide superior leak integrity without contamination from a non-metallic liner or seal.
  • Bonnet Vent Ports (1/8" NPT): Allow venting of hazardous gases in the event of diaphragm failure.
  • Standard Threaded Bonnet (with Optional Collar-Mount Nuts): For easy panel mounting.
  • Diaphragm Packless Valve (with 1/4" Compression Fitting): Promotes system purity.
  • Five Outlet Pressure Ranges: Provide application pressure compatibility.
  • CGA-Connection with Integral Check Valve: Prevents contamination during cylinder changeout.
