膜片式单向阀 钢球式单向阀 四氟式单向阀 过滤器 消音器

DXF系列膜片式单向阀采用滤网、磁铁、膜片自吸结构设计，从而使单向阀不受安装角度限制和反向压力大小的关系影响阀门的自动闭合，具有极小的流通阻力、流量大、内泄漏量几乎为零等特点，使空调能效比大有提高，使用寿命1000万次以上。该阀适用于所有制冷剂和大中型冷热空调系统。为保证产品正常闭合，内置滤网30目。

DXF series diaphragm type check valve with self suction filter structure design,magnet,diaphragm,so that the valve can beautomatically closed relationship between valve installation size and angle limit reverse pressure,with small flow resistance,large flow,internal leakage is almost zero,and other characteristics,the energy efficiency is better than that.The service lifeof more than 10 million times.The valve is suitable for all refrigerants and large and medium sized cold and hot airconditioningsystems.In order to ensure the normal closure of the product,the built-in filter screen is 30 mesh.
