ControlAir’s High Pressure Regulators and Air Filter Regulators are used extensively in the separation of oil and gas in the gas processing industry. Gas in the outlet stream initially goes through a High Pressure Regulator (Type 3500 Brass High Pressure Regulator or Type 3600 Stainless Steel High Pressure Regulator) for the first-cut pressure reduction. The Type 3500 includes 3 outles connections. One outlet is used to send supply pressure to a Liquid Level Controller (LLC) and control valve (CV) on the oil side. The second-cut pressure reduction occurs on the Type 1230 Big High Pressure Regulator. The third-cut pressure reduction occurs on the Type 1227 Little High Pressure Regulator. Finally, the outlet stream from each Type 1227 is sent to a Air Filter Regulator (Type 330 or Type 335 NACE) before it reaches the corresponding LLC and CV. The Air Filter Regulator (Type 330/Type 335) provides filtration of the natural gas, removing particulate matter and grit which can cause wear and tear on the LLC and CV. The Air Filter Regulator (Type 330/Type 335) reduces the pressure one final time, so the LLC has a suitable supply pressure for operation.
