BURKERT德國進口氣動式二位二通截止閥簡介
?Measured as overpressure to the atmospheric pressure Response times [ms]:
Opening? Closing Measured at valve outlet at 6 bar and +20oC. Pressure relief 0 90% Pressure drop 100 to 10%
cv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。，
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。

The actuator body is made out of epoxy resin.
主軸設計有雙層密封件，但沒有壓蓋。
緊湊型結構
2/2-way valve for medium up to +140oC
The externally controlled valve is pneumatically operated. It consists of a diaphragm actuator and a 2-way valve body.
驅動裝置外殼由環(huán)氧樹脂構成。
主軸設計有雙層密封件，但沒有壓蓋。

我國閥門“三化給”曾規(guī)定，截止閥的流向，一律采用自上而下。
截止閥開啟時，閥瓣的開啟*度，為公稱直徑的25%～30%時.流量已達到

The diaphragm actuator moves a spindle with valve disc against a spring and switches the valve.
The spindle is designed glandless with double seal.
Technical data Body material Brass, stainless steel Inner part valve Stainless steel
Actuator Epoxy resin Seal material NBR, FKM, PTFE/FKM, EPDM, PTFE/EPDM Medium NBR

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(chǎn)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(fā)生閥桿頂彎的故障。
