Product Description Structure 1.The valve disc moves up and down along the midline of the valve body. Under the pressure of the fluid which flows in one direction, the valve disc will be raised up from the sealing surface of the valve seat. If there is backflow, the valve disc will return back to the valve seat to cut off the medium. 2.To further reduce the impact, the lift check valve is engineered with piston dashpot, which is installed with spring.3.There are small holes on the piston. When the piston is moving, the medium will flow slowly, which will reduce the impacting force to the valve greatlyStandard Design and manufacture: API 6DFace to face: ANSI B 16.10Flange: ANSI B 16.5aButt welding end dimension: ANSI B 16.25Pressure test: API 6DAPI 598 Purpose API check valve is applied to petroleum, chemical, water power, thermal power station and other pipelines. It is used to cut off or turn-on the medium, for example water, oil, steam, etc.Main accessory materialDisc surface13Cr13CrSTL304STL316STLMonel304304STLSeat surface13CrSTLSTL304STL316STLMonel304304STLShellASTM A351 CF3ASTM A351 CF8MASTM A351 CF3MDisc and yokePin axesF304LF316F316LDisc surface304L304LSTL316316STL316L316LSTLSeat surface304LSTLSTL316STL STL316L316LSTL Main external dimension and weight mmClassSpec.dLL1DD1D2bZ-ФdH(turn on)Weight wt(kg) 15025120321615212192164-191591721/264216229178140105174-1916825376241254191152127194-19181294102292305229191157248-19203506152356368279241216258-22276858203495508343298270298-22330150102546226354063623243012-25381240123056997114834323813212-25410350143567878005334764133512-29524460164068648765975404703716-29572495 30025126728316512792228-191752821/264292308191149105258-2218133376318333210168127298-22191454102356371254200157328-222417061524454603182702163712-2230515082035335493813302704112-25362230102546226384453873244816-29425390123057117275214513815116-32451520143568388545845144135420-32549710 60025129229516512792258-192033221/264330333191149105298-2221942376356359210168127328-22238604102432485273216157388-2527911061525595623562922164812-2938122082036606644193492705612-32436390102547877915064323246416-35527630123058368415594893816720-35641870
