Product DescriptionMHP Series Forged High-temperature and High-pressure Regulating ValveMH series forged high-temperature and high-pressure cage type pressure reducing valve is an advanced product developed by Hangzhou Meiya to meet higher pressure (LB) operating conditions, with a max pressure rating of 2500 LB.The standard valve cage has a multi-hole structure, which featuring outstanding strength and excellent vibration resistance performance.The pressure reducing valve body is fully forged, demonstrating significantly superior mechanical properties compared to cast steel valves-including tensile strength, yield strength,and hardness.The pressure-reducing valve employs a dual-disc structure (main disc and pilot disc).During closuring, the main disc seats first on the valve seat by gravity before the pilot disc,converting medium's pressure into force on sealing surface of the main disc.During opening, since the sealing surface of the pilot valve core is much smaller than the main valve core, the output force of the actuator is greatly reduced.SpecificationMain Technical Specifications1.Flow characteristic: Equal percentage/linear/quick-opening2.Inherent adjustable ratio: 50:13.Leakage class: Conform to ANSI/FCI & IEC60534-4 IV(standard); V, VI(optional)4.Operating temp.:-29~545oC(Depend on the material's temperature limits )5.Intrinsic error: ±1%6.Backlash:±1%7.Dead zone:0.8%8.Connection standard:Butt weld connection: ASME B16.25-20079.Optional internals:Multi-stage pressure/noise reduction guide cageSectional viewPhysical photoValve internalsTechnical Specifications(Custom configurations available upon request.)No.ComponentMaterialTemperature range1Valve bodyF22/P91/12Cr1MoV-29~545oC(Depend on thematerial'stemperature limits)2Seat sealingring321stainless steel+graphite-29~593oC3Valveseat321bead weldSTL alloysame as valveservice temp.4Pilot valve core321bead weldSTL alloysame as valveservice temp.5Bonnet sealing ring321stainless steel+graphitesame as valveservice temp.6Valve core304stainless steelsame as valveservice temp.7Valve cage440Bstainless steelsame as valveservice temp.8PackingPTFE V-ring-29~232oC(other medium)PTFE+composite material-29~232oC (oxydic medium)soft graphite-29~538oC(other medium)soft graphite-29~371oC (oxydic medium)soft graphite(highO2 dennsity)-29~649oC9ValvestemA276 XM19/38CrMAlAsame as valveservice temp.10Packing bushing304stainless steel-29~593oCRated Flow CoefficientBasic ordering requirementsFor customized desuperheating and pressure-reducing devices or valves, please provide the corresponding data as presented in the table below.Device modelDevice nameQuantity (sets)Inlet steam flow rate Q(t/h)Range of changeImported steam pressure P1(MPa)Range of changeImported steam temperature T1(℃)Range of changeRated outlet steam pressure P2(MPa)Deviation rangeRated outlet steam temperature T2(℃)Deviation rangePressure of deheated water Pb(MPa)Range of changeTemperature of deheated water Tb(℃)Range of changeNoise(dBA)The layout method and structural form of the device1,Horizontal 2,VerticalDimensions of imported pipelinesFlangeDimensions of the outlet pipelineFlangeThe size of the desuperheating water pipeWeldingWeldingControl modeThe required documentsOthers1,Electric control 2,Pneumatic control 3,Hydraulic controlenforce standardsSpecial requirementsAfter Sales ServiceWarranty period: Within 12 months from the date of equipment acceptance and normal use, or 18 months from the date of arrival, whichever comes firstTraining: Remote operation/maintenance trainingAfter-sales service commitment: Lifetime provision of spare parts and maintenance services.
