6520 Series Two Stage Cylinder Regulator

Dual stage cylinder regulator for medium heavy-duty welding, heating and cutting applications
8066520-01-1 shown
Dual stage cylinder regulator for medium heavy-duty welding, heating and cutting applications

The 6520 Series two stage regulator is for medium-duty welding, heating, and cutting provide primary pressure control of industrial gas cylinders in applications requiring moderate flow rates with delivery pressures up to 200 PSIG (14 BAR). The encapsulated seat design increases pressure control accuracy and provides an extended component lifecycle, while the chloroprene diaphragm provides steady and reliable pressure control.

  • Medium-large seat displacement permits good flow capacity
  • Chloroprene diaphragm maintains steady pressure control
  • Chrome-plated, die-cast zinc bonnet provides clean appearance
  • Body: Forged brass
  • Bonnet: Chrome-plated, die-cast zinc
  • Gauges: 2 1/2 in (63 mm) diameter brass
  • Filter: 25-micron sintered bronze
  • Temperature range: -40°F to 140°F (-40°C to 60°C)
  • Seat (1st stage): PTFE
  • Diaphragm: Stainless steel
  • Cv: 0.2
  • Conformances: Cleanliness meets or exceeds CGA G-4.1; ANSI/ASME B40.1; CRN OH5216.5R2
