BelGAS General Purpose Type P40 and Type P40 NACE Natural Gas and Propane Regulators are reliable precision units designed for instrumentation and general purpose use in both standard (P40), and corrosive environments (P40 NACE). The P40 NACE complies with NACE material requirement MR0175 for sulfide stress cracking resistant metallic material for oil field equipment. Test data for these regulators show excellent performance characteristics compared with those of similar units presently on the market. These BelGAS regulators are generally superior in regulated pressure vs. flow, forward-to-reverse flow offset, supply pressure sensitivity, repeatability and stability. Ruggedly designed and constructed, the regulators have housings of diecast aluminum. The P40 Regulator is finished with vinyl paint (which resists scratching, weathering & other physical abuse), while the P40 NACE is supplied with an epoxy paint for added corrosion protection. Both the P40 and P40 NACE, are pressure and leak tested prior to shipment from the factory. The full flow gauge port is convenient for gauge installation and can also be used as an additional full flow outlet.
