GDH Series Purge Assemblies

GDH Series Purge Assemblies
Conoflow’s GDH series purge assemblies consist of a GH21XT series fixed differential pressure regulator piped to a needle valve equipped flow meter. The fixed differential pressure regulator maintains a constant pressure drop across the flow meter, resulting in consistent flow regardless of downstream pressure fluctuations.

Available in an economical brass construction, or in corrosion resistant stainless steel construction, these products can be used with air, or water at downstream pressures to 100 psig.  All purge assemblies are equipped with a plated steel mounting bracket.

Typical applications for these products include purge gas control, depth measurement (using constant bubbling of a dip tube) and water flush systems.
