卫生级法兰止回阀 Sanitary flange ball check valve 应用  止回阀应用于不锈钢管道系统内，以达到防止液体回流的目的。 工作原理  当阀杆下部的压力超过阀杆上面的压力以及弹簧力时，阀门就开启，当阀杆上、下压力平衡时，阀门就会关闭。一个更高的逆向压力作用于阀杆使其关闭 材质  产品与介质接触部分304或316L    密封材料: EPDM橡胶 连接形式  焊接式、螺纹式、止箍式、法兰式          与管道或设备的连接方式均按                   DIN11850,IDF/ISO"SMS国际标准尺寸制造，保障与进口设备的连接与互换。 技术数据   如果阀门被安装在一根垂直管道内，开启间门所需要的不同的压力大约为:                   最大输送物料压力:10bar       最高温度: 140℃ (EPDM )         最低温度:- 10℃   Sanitary flange ball check valve Application Checkvalve is used in stainless steel pipe system topreventreverse flow. Workingprinciple  Thevalve opens when the pressure below the valve plugexceedsthe pressure above the plug plus spring force. The valve close when pressureequalization has beenachievedA higher counter pressure will press the v alveplugagainstthe seat and makes the valve closed Material  Materialcintact surface     Sealing material: EPDM Connectionstyle    Welded,threaded ,clamped ,flange Toassure the connection and substitution with imported facilities all theConnection styles with pipe or equipment are made to DlN 11850,lDF/lSO,SMS internationalstandard size. Technical date   Roquireddifferential pressures to turn on the valve that fitted in a vertical pipeline areabout: Max.Pressure for transfer material:10 bar Max.Temperature: 140℃(EPDM) Min.Temperature:-10℃
