Regulators for Dispensing High-Purity Gases at High Flows
The series is designed with a balanced stem to accomplish high-glow capacity (Cv=1.0). The manufacturer states that the Series 485/483 in brass barstock and Series 486/484 in stainless steel barstock can provide a constant delivery pressure at high-flow, even during fluctuations in inlet pressure. In addition, these all-wetted contact surfaces of brass or 316L stainless steel barstock Kel-F or Teflon with a helium leak integrity of 1 × 10
The regulators are also built to allow for ease of installation in rear mounting threads, 0.5-in. inlet/outlet ports, and field-adjustable pressure limits customized to specific applications. Also standard are four inlet gauge selections, four outlet pressure ranges from 0- to 15-psig through 0- to 200-psig, a chrome-plated die-cast zinc bonnet, and a captive hand know with an adjustable pressure limit. A dome-loaded option is also available.
