Product Description Exd II BT4 Explosion-Proof Flanged Electric Ball ValveProduct profile:Category : Electric ball valveProduct Name: Explosion-proof Flanged Electric Ball ValveProduct introduction:Flange type explosion-proof electric ball valve is the rotation Angle of 0-90° ball valve with excellent sealing performance circulation capacity flow resistance coefficient is small simple structure convenient maintenance long service life valve channel and connection pipe diameter and into a diameter the medium can almost no loss of flow.The control mode can be switch on-off type or regulation type. Its usually used in the occasions with strict sealing requirements in addition to controlling gas liquid and steam medium it is also suitable for controlling sewage and medium containing fibrous impurities widely used in petroleum chemical industry metallurgy light industry paper making power station refrigeration and other work fields.The working principle of flanged electric ball valve is: the electric actuator drives the valve stem to drive a ball (or part of the ball) with a hole the ball rotates with the valve stem to realize the opening or closing of the valve;Electric ball valve can be fully closed and fully opened by rotating 0-90°. Compared with gate valve and globe valve of the same specification ball valve is small in size and light in weight which is convenient for pipe installation.No leakage of two sides self-seal ball structure. Special designed PTFE seal materialless the friction of the trim movement.Excellent cuting ability of O type valve trim Optional O type or Vtype valve trim The advantage of explosion-proof actuator: *All electrical and mechanical components are sealed in aluminum alloy shell with high instant explosion resistance pressure of 1.6MPa isolating the ignition source effectively. *With "o "ring seal up to protection grade IP68 Each explosion-proof surface adopts circular clearance and CNC precision machining to achieve stable and reliable explosion-proof performance *Powered by 1-phase 3-phase or DC power supplies *Bus communication, Analog signal are available for your choice *Permanently lubricated and maintenance free drive train *Optional torque limiter/remote controlExplosion-proof grade: TA: explosion-proof series products of explosion-proof level for Exd II BT4 The Ex D: Explosion-proof type: Explosion-proof II : Electrical equipment used in explosive gas environment except the coal mine of device B: Explosion level: the size (width and clearance) of the explosion-proof surface in accordance with the explosion level T4: Temperature group: the maximum temperature in surface is 135oC In appendix B of GB3836.1-2000 the grade and temperature of combustible gas are listed in detail [NOTED] the types and groups of explosive media around the place where the product is used must be consistent with those permitted by the product.Otherwise it can't play the explosion-proof effect in non-applicable environmentPRODUCT CHARACTERISTICSPower supplyAC220V 50/60HZNominal diameterDN15-200Medium temp.-20oC ~ +350oC (+200oC special PPL)Nominal pressurePN16 PN25,PN40,PN64,PN100Input signal4-20mADC1~5VDC Output signal4-20mADCConnection typeFlangeBody materialA105,F304,F316,WCB,FZG1Cr18Ni9Ti,ZG1Cr18Ni12Mo2Ti,CF8,CF8M,CF3MValve seat materialPTFE(Nomal temp.),PPL(Medium temp.),STL Metal seal(High temp.)Leakage class Conformed to ANSIB16.104 -V classSeal typeSoft seal ,PPL,Metal seal Ceramic Suited mediumWater,Petroleum,Nitric acid,Acetic acid,Viscous fluid,Pulp,OxidantProtection classIP68Manufacture standardJB/T8692-1998Length standardGB1221-89Inspection standardJB/T 9092 API598Figure and size:SizeLDKD1bN/1iHW15130956545144-?142209196201301057555164-?142211196251421138565184-?142218.51963216514010078184-?1822331964016515011085184-?18223419650203165120100204-?18224819665222185145120208-?18229425580241200160135218-?182320255100305220180155228-?182339255125356250210184228-?183392255150394285240210248-?233402255200457340295265268-?233467255Wire Connection DiagramCertificatesAs a Hi-Tech enterprise,we have our Design Team for innovation and customization.For these years,we achive more than 20 kinds of proprietary technology to make our product more powerful.Company IntroductionWuhan Grat Control Valve is a professional valve manufacturer established in 2005.It is specialized in researching and developing various automatic valves for industrial automation and on-site implimentation products.
