The pipe line system in most cities of China adopt the medium-pressure transportation (usually between 1-4bar),however,the direct-fired equipment,such as the gas-fired boiler and thedirect fired central air-conditioning units need low-pressure gas(usually between 50-100mbr).As a result,the company designs and creates the CHZ series direct fired equipment pressure adjustment system.

This series product takes the features of industrial gas using into consideration --sudden changes of gas flow,requirement of quick start and stop ,non-stopping gas supply,etc.)lts functions include automatic double-way switching, filtrating,adjusting the pressure and measuring.When there is rapid change of gas flow ,this pressure regulator can respond quickly to adjust and ensure the stability of pressure and stop when needed. This can greatly help the operation of both industrial and civil direct-fired equipment
