德國(guó)BURKERT二位二通氣動(dòng)閥安裝說(shuō)明

 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%
動(dòng)作快遞，功率微小，外形輕巧
電磁閥響應(yīng)時(shí)間可以短幾個(gè)毫秒，即使是導(dǎo)式電磁閥也可以控制在幾十毫秒內(nèi)。
外殼材料：黃銅、不銹鋼、
還可做到只需觸發(fā)動(dòng)作，自動(dòng)保持閥位，平時(shí)點(diǎn)也不耗電。
Circuit Function B 2/2-way valve, externally controlled, normally opened by spring, operation with pilot valve
Type 0262 can be combined with.
• Normally closed or open • Body material: Brass, Stainless steel
• Double spindle seal • Compact design
電磁閥外形尺寸小，既節(jié)省空間，又輕巧美觀。
調(diào)節(jié)精度受限，適用介質(zhì)受限
neutral medium (e.g. compressed air, town gas, water, hydraulic oil) per-solution, oxygen, hot air oil and fat-free medium e.g. hot water,
 alkaline washing and bleaching lyes oil and fat-free medium, e.g. hot water and steam
hot oils, hydrocarbonated water, aromatics and steam
隔膜驅(qū)動(dòng)裝置能夠使主軸
連同閥錐朝彈簧的方向運(yùn)動(dòng)，進(jìn)而接通閥門(mén)。
主軸設(shè)計(jì)有雙層密封件，但沒(méi)有壓蓋。
另外，粘稠狀介質(zhì)不能適用，而且，特定的產(chǎn)品適用的介質(zhì)粘度范圍相對(duì)較窄。
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
 PTFE/EPDM (PFTE seal with EPDM O-Ring) PTFE/FKM (PTFE seal with FKM O-Ring)
電磁閥通常只有開(kāi)關(guān)兩種狀態(tài)，閥芯只能處于兩個(gè)限位置，
驅(qū)動(dòng)裝置外殼由環(huán)氧樹(shù)脂構(gòu)成。
無(wú)流量時(shí)關(guān)閉或打開(kāi)

由于自成回路，比之其它自控閥反應(yīng)更靈敏。
緊湊型結(jié)構(gòu)
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.
雙主軸密封件
這種外部控制的直通閥經(jīng)由氣動(dòng)操作。
它由個(gè)隔膜驅(qū)動(dòng)裝置和個(gè)二通閥套構(gòu)成。

設(shè)計(jì)得當(dāng)?shù)碾姶砰y線圈功率消耗很低，屬節(jié)能產(chǎn)品；
The diaphragm actuator moves a spindle with valve disc against a spring and switches the valve.
 The spindle is designed glandless with double seal.
The actuator body is made out of epoxy resin.
不能連續(xù)調(diào)節(jié)，所以調(diào)節(jié)精度還受到定限制。
電磁閥對(duì)介質(zhì)潔凈度有較高要求，含顆粒狀的介質(zhì)不能適用，如屬雜質(zhì)須濾去。
