Itron-Actaris 757631 Aluminum Orifice 3/8" DIA

The Itron-Actaris 757631 Aluminum Orifice regulates gas flow rates through metering systems, pressure regulators, and distribution parts requiring precise volumetric control. This 3/8-inch diameter slit plate creates calibrated flow restrictions within gas passages, generating pressure drops that correspond to specific flow volumes. Machined aluminum construction provides corrosion resistance natural gas constituents while maintaining dimensional stability across temperature variations encountered in calibration installations of HVAC systems. The orifice's fixed aperture size maximum flow capacity, protects downstream components from excessive velocities, and enables accurate measurement when paired with differential pressure sensors.
