Fiorentini 31051-1BS 1/2" Unpainted Balanced Valve 4" Diaphragm 1/4" Vent Black Spring 6"-14" 2 PSIG MAOP

The Fiorentini 31051-1BS 1/2" Unpainted Balanced Valve 4" Diaphragm 1/4" Vent Black Spring 6"-14" 2 PSIG MAOP is a pressure-regulating part that controls gas flow according to diaphragm movement within HVAC systems. Installed in the gas supply line, it balances inlet pressure against spring force and diaphragm position to regulate outlet pressure during operation. Internal pressure changes communicate with the diaphragm, valve seat, and connected gas control components, allowing controlled flow adjustments as operating conditions vary. Its support stable gas regulation by maintaining controlled pressure delivery throughout connected gas distribution circuits.
