Product DescriptionMZ Series Single-Seated Regulating ValveThe MZ series single-seated regulating valve is a dual- purpose solution for water and steam systems, ideal for deaerated water or handling non-lubricating, viscous, andchallenging fluids. Its "rear-guided design" stabilizes the valve core within the guide cage, reducing noise, vibration, and valve trim wear.The valve cover adopts a spring-loaded packing design.The packing is made of PTFE V-rings, flexible graphite or dual packing with dynamic loading, which reduces the movement resistance of the moving parts and minimizes the maintenance of the packing.Different valve core types can be selected according to different working conditions to achieve different flow characteristics.Standard valve cores include equal percentage, linear and quick-opening characteristics.The valve uses a top-compressed seat ring design to minimize disassembly time and enable direct online servicing or maintenance without pipeline removal.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.:-29oC-300oC (Depend on the material's temperature limits)5.Intrinsic error: ±1%6.Backlash:±1%7.Dead zone:0.8%8.Connection standard:Flange connection:ASME B16.5Threaded/socket weld connection: ASME B16.11Butt weld connection:ASME B16.259.Optional internals:Micro-flow valve coreSectional viewPhysical photoValve internalsTechnical Specifications(Custom configurations available upon request.)No.ComponentMaterialTemperature range1Valve bobyWCB/WC6, WC9/CF8, CF3M-196~593oC(Depend on thematerial's temperature limits)2Seat sealingring316 stainless steel+graphite-196~593oC3Valveseat304/410same as valveservice temp.4Guide cage304/17-4PH/CA6NM304/same as valveservice temp.5Valve core410 stainlesssteelsame as valveservice temp.6Spring304/17 -4HP-196~593oC7Bonnet sealing ring304stainless steel +graphitesame as valveservice temp.8Packing bushing304 stainlesssteel-196~593oC9PackingPTFE V-ring-40~232oC (other medium)PTFE + composite material-73~232oC (oxydic medium)soft graphite-196~538oC(other medium)-196~371oC(oxydic medium)soft graphite(high O2density)-196~593oCProduct Dimensions (mm)Basic 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.
