High Pressure Regulators
Series 3860T

Description

The Series 3860T high pressure regulators are designed to safely reduce inlet pressures from cylinders filled with gases to 6000 psig. The self-venting feature of the regulator allows the operator to reduce the pressure setting in a closed system by venting the downstream pressure through the regulator.

Features

  • Full 6000 psig delivery pressure capability.
  • Available in brass or stainless steel.
  • Self-venting design for ease of pressure adjustment.
  • Unbalanced stem assures positive shut-off.
  • Removable valve assembly module permits ease of repairs.
  • Large adjusting knob provides fast low-torque pressure settings.

  • *Specify CGA Connection Number when ordering.
  • Add prefix “NV” to model number if self-venting feature is not desired (i.e. NV3860TB-6000-677).
  • Self-venting feature is not recommended with flammable or toxic gases.
  • **Regulators fitted with a CGA connection rated for 3000 psig will have a 0-4000 psig brass, or 0-3000 psig SS inlet pressure gauge.
