Fixed Orifice Double Regulating Valve
The BLAZE Fixed Orifice Double Regulating Valve (FODRV) is a precision-engineered solution balancing flow in potable water, HVAC, and mechanical systems. Designed for reliable performance, tne vaive features an integral orifice plate that forms a fixed orifice flow measurement unit, allowing accurate commissioning, regulation, and isolation of flow circuits. Manufactured with a ductile iron body and coated with Fusion Bonded Epoxy (RAL 5015 Blue), it offers excellent protection against corrosion and ensures safe use in potable water systems. A lockable handwheel with position indicator supports repeatable settings, while built-in test points allow direct differential pressure readings for flow verification.
