Item Details

  • This series of two-stage, high-purity 316 stainless steel regulators is designed for non-corrosive analytical and process applications requiring precise, stable delivery pressure control. The two-stage design yields a delivery pressure change of less than 0.04/100 psi inlet change. Convoluted 316 stainless steel diaphragms provide excellent regulating characteristics and corrosion resistance, and the threaded-seat design allows for internal vacuum purging. The metal-to-metal diaphragm seal prevents contamination by eliminating the need for a soft seal and provides a leak-rate design of less than 2 x 10–8ccs helium. This minimizes cleanup time in vacuum purging and yields lower residual contaminant levels. A diaphragm packless outlet valve with a 1/4" compression fitting is provided for flow control and to maintain system purity. Captured bonnet ports with optional vent adapters are standard on both stages and allow the venting of hazardous gases in the event of diaphragm failure. These regulators are ultrasonically cleaned for the most demanding high-purity service.

Features

  • Filtered Seat for added gas stream purity and extended service life.
  • Convoluted 316 Stainless Steel Diaphragms provide superior leak integrity without contamination from a non-metallic liner or seal.
  • Bonnet Vent Ports (with optional bonnet vent adapters) 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.
  • Four Outlet Pressure Ranges provide application pressure compatibility.
