High Flow Gas Pressure Regulator Reliable pressure control for the oil and gas industry The Type 1227 Pressure Regulator is a pressurereducing, direct-operated regulator suitable for use with compressed air, natural gas, or an assortment of other inert gases. The Type 1227 is available with output ranges that span from 5 psi up to 150 psi and can be ordered with a variety of orifice sizes and materials providing application flexibility in the oil and gas industries. Features • Wide range of orifice sizes for different flow capacities • 1" or 2" body size • Guarded against unwanted set point adjustment with tamper-proof cap • Monitoring Option (M) provides downstream feedback control line • Trim can be replaced without disconnecting regulator from the system • Can be re-arranged into multiple orientations for difficult installations with limited maneuverability • Superior Sensitivity • NACE MR0175 construction available • Assembled and Tested in the USA Materials of Construction Body Bonnet, Diaphragm Case Diaphragm Valve Disk Trim Ductile Iron Nitrile Nitrile (Nylon option) Aluminum (stainless option)

Type 1227 High Flow Gas Pressure Regulator Principles of Operation Note: The ControlAir Type 1227 High Flow Gas Pressure Regulator does not include internal relief. Therefore, if the inlet pressure is able to exceed the diaphragm casing pressure rating, the user must provide a pressure relieving device.
