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. These regulators come with a CGA-nipple that has a special high-purity, non-lubricated check valve incorporated into nose and prevents air and contaminants from entering the gas stream during cylinder change out. This creates consistencies in processes and extends column life in GC applications. 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 adapter 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: Provides superior leak integrity without contamination from a non-metallic liner or seal.
  • Bonnet Vent Ports (with Optional Bonnet Vent adapters): Allows venting of hazardous gases in the event of diaphragm failure.
  • Metal-to-Metal Seal: For High Purity.
  • Standard Threaded Bonnet (with Optional Collar-Mount Nuts): For easy panel mounting.
  • Diaphragm Packless Valve (with 1/4” Compression Fitting): Promotes system purity.
  • Six Outlet Pressure Ranges: Provides application pressure compatibility.
  • CGA-Connection with Integral Check Valve: Prevents contamination during cylinder changeout.
