原裝力士樂REXROTH截止閥，力士樂截止閥簡單介紹：
力士樂REXROTH截止閥又稱截門閥，屬于強制密封式閥門，所以在閥門關閉時，必須向閥瓣施加壓力，以強制密封面不泄漏。當介質由閥瓣下方進入閥門時，操作力所需要克服的阻力，是閥桿和填料的摩擦力與由介質的壓力所產生的推力，關閥門的力比開閥門的力大，所以閥桿的直徑要大，否則會發生閥桿頂彎的故障。按連接方式分為三種：法蘭連接、絲扣連接、焊接連接。從自密封的閥門出現后，截止閥的介質流向就改由閥瓣上方進入閥腔，這時在介質壓力作用下，關閥門的力小，而開閥門的力大，閥桿的直徑可以相應地減少。同時，在介質作用下，這種形式的閥門也較嚴密。我國閥門“三化給"曾規定，截止閥的流向，一律采用自上而下。截止閥開啟時，閥瓣的開啟高度，為公稱直徑的25%～30%時.流量已達到zui大，表示閥門已達全開位置。所以截止閥的全開位置，應由閥瓣的行程來決定。
原裝力士樂REXROTH截止閥，公司從事液壓、工控、氣動產品行業多年，在市場上擁有良好的口碑，經驗豐富，業務遍布全國，已被很過歐美進口廠家認定為一級經銷經銷商，所以價格是非常有優勢的，產品包括液壓元件、氣動元件、工控產品、電磁閥閥、泵、傳感器、壓力開關、空氣處理設備、污水處理設備等等歐美進口自動化設備。原裝*正品，假一賠十，在德國不萊梅有分公司，所有貨源直接跟廠家合作采購，沒有經過任何中間商，價格低，貨源穩定，貨期短，還可以提供報關單跟物流，我司在國內也有三家公司，其中上海分公司為總部可以自己報關。我公司本著“用戶至上，信譽*！"的宗旨，歡迎廣大新老客戶！
，截止閥（stopvalve,GlobeValve）的啟閉件是塞形的閥瓣，密封上面呈平面或海錐面，閥瓣沿閥座的中心線作直線運動。閥桿的運動形式，（通用名稱：暗桿），也有升降旋轉桿式可用于控制空氣、水、蒸汽、各種腐蝕性介質、泥漿、油品、液態金屬和放射性介質等各種類型流體的流動。因此，這種類型的截流截止閥閥門非常適合作為切斷或調節以及節流用。由于該類閥門的閥桿開啟或關閉行程相對較短，而且具有非常可靠的切斷功能，又由于閥座通口的變化與閥瓣的行程成正比例關系，非常適合于對流量的調節。
