Genebre Art2228 Ductile Iron Variable Orifice Double Regulating Valve (PN16 Flanged)

Genebre Art2228 Ductile Iron Double Regulating Valve (PN16)

The Genebre Art2228 is a globe pattern, variable orifice double regulating valve designed for accurate flow measurement, regulation and isolation in heating and cooling systems. Commonly used as a commissioning and balancing valve, it allows precise control of system flow while maintaining repeatable settings.

Constructed from painted ductile iron EN GJS 450, the valve features flanged PN16 ends and an EPDM body gasket for reliable sealing. The valve is supplied with integral test points and a presetting mechanism, allowing flow rates to be measured and the valve position to be locked once commissioning is complete.
