CYL-1 Series
Pressure Regulators

CYL-1 Series Cylinder Pressure Regulator

The CYL-1 Series is designed as a complete compact pressure control module. The basis of this unit is the economical PR-2 Series pressure control valve which is widely used in instrumentation sample systems as well as many other applications requiring maximum reliability. This regulator, when ordered with the appropriate gauges and CGA inlet fitting, is designed as a compressed gas cylinder regulator for those applications where the corrosion resistance of stainless steel is not a requirement.
