GO Regulator CYL-21 Series Pressure Regulators
Corrosion-resistant Single Stage Cylinder Regulator
The GO Regulator CYL-21 Series Pressure Regulators are compact cylinder regulator based on the time proven design of the PR-1 single-stage line regulators. While normally used for low and moderate flow service, optional high flow orifices are available. The standard unit is equipped with CGA connector, integral inlet filter, inlet and outlet pressure gauges and may be ordered with extra inlet or outlet ports for inlet purging, outlet relief valves or other accessory items. When used in service with toxic or explosive gases, we recommend the installation of a captured vent option. This option is a true captured vent cap and not merely a standard cap with a vent port. It comes complete with a CGA fitting and 2˝ diameter gauges.
