CYL21 SINGLE STAGE CYLINDER PRESSURE REGULATOR

The CYL21 Series is a compact cylinder regulator based on the time proven design of the PR1 Series single stage stainless steel line regulator and is suitable for most corrosive gas cylinder applications. While normally used for low and moderate flow service, optional high flow orifices are available.

The standard unit is equipped with cylinder/bottle 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 cylinder/bottle fitting and 2" diameter gauges.
