寶碩直動式電磁閥文檔,BUSCJOST直動式電磁閥技術介紹
直動式電磁閥，通電時，電磁線圈產生電磁力把關閉件從閥座上提起，
閥門打開；斷電時，電磁力消失，彈簧把關閉件壓在閥座上，閥門關閉。
它是種直動和導式相結合的原理，當入口與出口沒有壓差時，
通電后，電磁力直接把導小閥和主閥關閉件依次向上提起，閥門打開。
The valves of this series, including the connection size DN 25
(G 1), are according to Art. 3 § 3 of the Pressure Equipment Directive
(PED) 97/23/EG. This means interpretation and production are in
accordance to engineers practice wellknown in the member countries
當入口與出口達到啟動壓差時，通電后，電磁力導小閥，主閥下腔壓力上升，
上腔壓力下降，從而利用壓差把主閥向上推開；斷電時，
導閥利用彈簧力或介質壓力推動關閉件，向下移動，使閥門關閉。

Note to Electromagnetic Compatibility Guideline (EEC):
The valves shall be provided with an electrical circuit which ensures
the limits of the harmonised standards EN 61000-6-3 and
EN 61000-6-1 are observed, and hence the requirements of the
Electromagnetic Compatibility Guideline (2004/108/EG) satisfield.
特點：1.在真空、負壓、零壓時能正常工作，但通徑般不超過25mm。
2.在零壓差或真空、高壓時亦可動作，但功率較大，要求必須水平安裝。

For valves > DN 25 (G 1) Art. 3 § (1) .4 applies.
The basic requirements of the Enclosure I of the PED must be fulfilled.
The CE-sign at the valve includes the PED. A certificate of conformity of
this directive will be available on request.
