Model SSC

Low Delivery Pressure, General Purpose Regulators

This regulator provides accurate control at very low delivery pressures. It is available in five separate delivery pressure ranges: from 3.5"-8" H2O to 10-15 psig.

Line Regulatr Model SSC Model SSC is mainly designed for use with liquefied hydrocarbons such as Propane, Butane or Isobutane. Although primarily used as a line regulator, it may be optionally ordered as a cylinder regulator for use with gases having cylinder pressures below 250 psig. For high pressure cylinder products (e.g., Nitrogen or Argon) in applications requiring very low delivery pressures please refer to our Models TSC and THP Regulators.

Warning: Do not use this regulator with Hydrogen or Helium. Although these gases are compatible with the materials of construction, experience shows that the seals are not sufficient to prevent leakage of these gases.This regulator is also not recommended for oxygen service.

Standard Features
  • Large Molded Diaphragm allows for accurate control of delivery pressures as low as 3.5" H2O.
  • Adjusting Screw is Concealed by Security Cap to help prevent adjustments by unauthorized personnel.
  • Threaded Mounting Pads with screws permit panel mounting.
  • Outlet Metering Valve provides flow control.
  • 1" H2O Graduations on SSC-0 Gauge and 1 oz. Graduations on SSC-1 Gauge allow for enhanced readability at very low pressure settings.
