High Flow Gas Pressure Regulator Reliable pressure control for the oil and gas industry The Type 1230 is a pressure-reducing, directoperated regulator suitable for use with compressed air, natural gas, or an assortment of other inert gases. The Type 1230 utilizes a similar design to the Type 1227 but provides a much broader offering of output pressure ranges and valve disk materials. The Type 1230 is available with output pressures that span from 50 psi to 500 psi making it suitable for use across a vast range of industries and applications, especially those utilizing regulators in series for controlled pressure reduction across multiple stages. Features •1" or 2" body size • Trim can be replaced without disconnecting regulator from the system • Can be re-arranged into multiple orientations for difficult installations with limited maneuverability • NACE MR-0175 configurations available • Assembled and Tested in the USA Materials of Construction Standard (S) Body, Bonnet, Diaphragm Case Diaphragm Valve Disk Trim LCC Steel Neoprene Nitrile or Nylon Brass and Aluminum (stainless option) LCC Steel Fluorocarbon Fluorocarbon or Nylon St
