原裝力士樂(lè)REXROTH截止閥屬于強(qiáng)制密封式閥門(mén)，所以在閥門(mén)關(guān)閉時(shí)，必須向閥瓣施加壓力，以強(qiáng)制密封面不泄漏。當(dāng)介質(zhì)由閥瓣下方進(jìn)入閥門(mén)時(shí)，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(zhì)的壓力所產(chǎn)生的推力，關(guān)閥門(mén)的力比開(kāi)閥門(mén)的力大，所以閥桿的直徑要大，否則會(huì)發(fā)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。

原裝力士樂(lè)REXROTH截止閥，力士樂(lè)截止閥簡(jiǎn)單介紹：
力士樂(lè)REXROTH截止閥又稱(chēng)截門(mén)閥，屬于強(qiáng)制密封式閥門(mén)，所以在閥門(mén)關(guān)閉時(shí)，必須向閥瓣施加壓力，以強(qiáng)制密封面不泄漏。當(dāng)介質(zhì)由閥瓣下方進(jìn)入閥門(mén)時(shí)，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(zhì)的壓力所產(chǎn)生的推力，關(guān)閥門(mén)的力比開(kāi)閥門(mén)的力大，所以閥桿的直徑要大，否則會(huì)發(fā)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(mén)出現(xiàn)后，截止閥的介質(zhì)流向就改由閥瓣上方進(jìn)入閥腔，這時(shí)在介質(zhì)壓力作用下，關(guān)閥門(mén)的力小，而開(kāi)閥門(mén)的力大，閥桿的直徑可以相應(yīng)地減少。同時(shí)，在介質(zhì)作用下，這種形式的閥門(mén)也較嚴(yán)密。我國(guó)閥門(mén)“三化給"曾規(guī)定，截止閥的流向，一律采用自上而下。截止閥開(kāi)啟時(shí)，閥瓣的開(kāi)啟高度，為公稱(chēng)直徑的25%～30%時(shí).流量已達(dá)到zui大，表示閥門(mén)已達(dá)全開(kāi)位置。所以截止閥的全開(kāi)位置，應(yīng)由閥瓣的行程來(lái)決定。
原裝力士樂(lè)REXROTH截止閥，公司從事液壓、工控、氣動(dòng)產(chǎn)品行業(yè)多年，在市場(chǎng)上擁有良好的口碑，經(jīng)驗(yàn)豐富，業(yè)務(wù)遍布全國(guó)，已被很過(guò)歐美進(jìn)口廠家認(rèn)定為一級(jí)經(jīng)銷(xiāo)經(jīng)銷(xiāo)商，所以?xún)r(jià)格是非常有優(yōu)勢(shì)的，產(chǎn)品包括液壓元件、氣動(dòng)元件、工控產(chǎn)品、電磁閥閥、泵、傳感器、壓力開(kāi)關(guān)、空氣處理設(shè)備、污水處理設(shè)備等等歐美進(jìn)口自動(dòng)化設(shè)備。原裝*正品，假一賠十，在德國(guó)不萊梅有分公司，所有貨源直接跟廠家合作采購(gòu)，沒(méi)有經(jīng)過(guò)任何中間商，價(jià)格低，貨源穩(wěn)定，貨期短，還可以提供報(bào)關(guān)單跟物流，我司在國(guó)內(nèi)也有三家公司，其中上海分公司為總部可以自己報(bào)關(guān)。我公司本著“用戶(hù)至上，信譽(yù)*！"的宗旨，歡迎廣大新老客戶(hù)！
，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(yùn)動(dòng)。閥桿的運(yùn)動(dòng)形式，（通用名稱(chēng)：暗桿），也有升降旋轉(zhuǎn)桿式可用于控制空氣、水、蒸汽、各種腐蝕性介質(zhì)、泥漿、油品、液態(tài)金屬和放射性介質(zhì)等各種類(lèi)型流體的流動(dòng)。因此，這種類(lèi)型的截流截止閥閥門(mén)非常適合作為切斷或調(diào)節(jié)以及節(jié)流用。由于該類(lèi)閥門(mén)的閥桿開(kāi)啟或關(guān)閉行程相對(duì)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(guān)系，非常適合于對(duì)流量的調(diào)節(jié)。
