The check valve, which is installed in the pipleline system , isan automatic valve that can turn itself on or off depending on the pressure of the medium. It’s main fuction is to prevent the medium from back. Wafer check valve, which is suitable the nominal presssure between PN 1.0MPa to 42.0Mpa. Class 150 to 2500 ; inside nominal diameter between DN15 to 1200mm. NPS between 1/2 to 48; It can be used in all kinds of piplelines and the temperture between 196℃ to 540℃. Pass to wash a material of using the dissimilarity, the valve can be fit for some kinds of medium just as water. vapor. Oil. nitric acid.acetic acid.strong oxidizing property mediumd and urea etc.

2. Contain 90%, the 3 MMs thick heap valve sits, or the high performance resin valve, can satisfy a bearing of variety to decay a request.
3. The V type combination seals completely a turn, can be under the sistuation that not unload to operate machine carry on replacing.
4. Sealing completely the gum adds a pour spout design, can prolong a valve door an usage period.
5. Stalk with is from smooth material, need not to add to lubricate a fat, wear away to the valve stalk small.
6. The fills a body mold to press a hot pack gum, having no rubber gum to fall and flushing a corrosive misgiving.
7. Valve cover and valve body seal completely with an O type turn, the stud bolt amount lets up, the convenience maintains.
8. Ideal song lines, can conduct and actions regulate a valve usage.
9. Provide a valve door the import and export manometer to deal with contact, be convenient for the customer to control and measurese process.
10. Keeping flows a way, the cylinder form valve body designs, depositing the thing not easy rules distance.
11. Open one degree manifestation and open one degree memory, convenient customer operation.
12. Can install to move to move compatibly.I am dynamoelectric to operate machine.
