6500 Series Industrial Cylinder Regulator

Single stage cylinder and station regulator for medium heavy-duty welding, heating, and cutting pipeline applications
8066506-01-1 shown

The 6500 Series medium heavy-duty welding, heating, and cutting regulator provides primary control of industrial gas cylinders in applications requiring outlet pressures up to 200 PSIG (14 BAR). Rugged forged brass construction provides high durability, while the encapsulated seat design maintains accurate pressure control and extended component lifecycle.

  • 2.5 in chloroprene diaphragm ensures steady pressure control
  • Medium-large seat displacement supports high flow capacity
  • Sintered filter provides additional safety and extends regulator life
  • CAPSULE® seat design provides maximum reliability and easy maintenance
  • 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)
  • Diaphragm: Chloroprene
  • Cv: 0.2
  • Conformances: Cleanliness meets or exceeds CGA G-4.1; ANSI/ASME B40.1; CRN OH5216.5R2
