2. Structure Comparison

The inter regulation structure of Fisher direct-acting regulator (RTZ-50SN) adopt balance 

valve element structure.

Runfeng RTZ-50AQ regulator adopt compound balance valve element structure, this kind of

 structure improve the accuracy of control pressure, it can stabilize the after pressure

 at a certain range well. RTZ-50AQ regulator with safety shut-off valve.
