Series 320

The Series 320 are high purity two stage regulator designed for corrosive and non-corrosive gases requiring precise and stable delivery pressure control.

These regulators provide constant delivery pressure regardless of inlet pressure fluctuations. This stainless steel regulator offers high corrosion resistance and wetted parts of 316 Stainless Steel and PCTFE for high purity applications.

This regulator also features a unique metal diaphragm seal. Captured vent ports are provided for both stages to allow for venting of hazardous gases in the event of a diaphragm failure.

This regulator is designed to withstand internal vacuums during purging operations.

Note: A Cross Purge Assembly must be used with this series of regulators to ensure effective purging of hazardous gas traces during cylinder changes.
