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. Specifications Body Sizes 1" or 2" NPT 10-95 psi (0.7-6.4 bar), 35-80 psi (2.4-5.5 bar), 70-150 psi (4.8-10.3 bar) Maximum Inlet Pressure see Table 1 Body Inlet Pressure Rating LCC Steel 2,000 psi (138 bar) Valve Disk Inlet Pressure Rating Nitrile (NBR) Disk 1000 psi (69 bar) Nylon (PA)...
