marsh bellofram过滤调压阀962-173-200 marsh bellofram 过滤调压阀 Type 50 & Type 50 NACE Filter Regulators Type 50 & Type 50 NACE Filter Regulators Superior regulation characteristics Rugged, corrosion-resistant construction Excellent stability and repeatability Self-relieving Integral, 40 micron, self cleaning filter Low droop at high flow The Type 50 NACE is available for use in corrosive environments. This complies with NACE material requirement #MR0175 for sulfide stress cracking resistant metallic material for oil field equipment. Product Detail: Marsh Bellofram’s General Purpose Type 50 & Type 50 NACE Filter Regulators are reliable precision units designed for instrumentation and general purpose use in both standard environments (Type 50), and corrosive environments (Type 50 NACE). The Type 50 NACE complies with NACE material requirement #MR-01-75 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 Marsh Bellofram 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 Type 50 Regulator is finished with vinyl paint (which resists scratching, weathering & other physical abuse), while the Type 50 NACE is finished with epoxy paint for added protection. Both models are pressure and leak tested prior to shipment from the factory. Careful design and quality materials throughout assure long, trouble-free operation in the most difficult industrial environments. A rubberized, soft-seat valve stem provides positive shut-off and “forgives” dirt or other foreign matter. An aspirator maintains downstream pressure and compensates for droop when high flow occurs.
