It worked by pneumatic actuator. Features1.Eesy to install and unloading. Kinds of connection will be suitable for any work place.2.No leakage and less noise. The sealing material will stop leakage.3.The closed structure is safe and stable. It could work for long time.4.Save power and automatical, less labor.Material of partsValve body, bonnetHT200, ZG230-450 ZG1Cr18Ni9TiValve disc, seat1Cr18Ni9Ti, surfacing of Stellite alloySoft seal discreinforced polytetrafluoroethylenePackingPTFE, flexible graphiteCorrugated tube1Cr18Ni9TiGasketrubber asbestos board, 10, 1Cr18Ni9Ti, asbestos spiral wound gasketDiaphragm coverA3Corrugated diaphragmnitrile rubber clip reinforced polyester fabricSpring60Si2MnStem, push rod2Cr13, 1Cr18Ni9TiBushing2Cr13Technical Parameters DN (mm )(dn)20253240506580100125150200(10)(12)(15)(20)KvLiner1.82.84.46.91117.627.54469110176275440690Percentage1.62.54.06.31016254063100160250400630Rated stroke L (mm)16254060Diaphragm effective area Ae (cm2 )2804006001000Signal range Pr (kPa)20 ~ 100 , 40 ~ 200Air pressure Ps (MPa)0.14 ~ 0.4Flow characteristicsStraight line, equal percentageAdjustable ratio50Allowable leakageHard sealing: IV  soft sealing: VI PN(MPa)1.0 , 1.6 , 4.0 , 6.4Working temperature t( ºC )Normal-20 ~ 200 , -40 ~ 250 , -60 ~ 250Cooling-40 ~ 450 , -60 ~ 450High450 ~ 560Low-60 ~ -100 , -100 ~ -200 , -200 ~ -250Picture Details and dimensionsDNLHH1Weight(kg)φAPN16PN40PN64NormalHigh TPN6PN16PN40PN64PN6PN16PN40PN642018019420639854845526519232852518519721041056050577020244022223525145562065758526355025426728645762770829030406527629231161079080921004766360802983173376228079510010755781003523683946408501051101171256599150451473508870113013214215017213016047020060065089011501601701872071752502507307751203152318720222523535047058030085090012341554220230257265500660More Products  Control ValvePneumatic Control ValveElectric Control ValveManual Control ValveSelf Operated Control ValveBall ValvePneumatic Ball ValveElectric Ball ValveManual Ball ValveButterfly ValvePneumatic Butterfly ValveElectric Butterfly ValveManual Butterfly ValveOther ValvesGlobe ValveGate ValveCheck ValveReducing ValvePlug ValveSafety ValveABOUT US  /* March 10, 2023 17:59:20 */!function(){function s(e,r){var a,o={};try{e&&e.split(",").forEach(function(e,t){e&&(a=e.match(/(.*?):(.*)$/))&&1
