4、 EG941W (unlined), EG941J (rubber lined) electric diaphragm valve structural characteristics:

1. Compact structure, small volume, light weight, easy assembly and disassembly;

2: High transmission efficiency;

3: Smooth operation and low noise;

4: Long service life;

5: Can transport media without leakage;

6: Can withstand no-load operation;

7: No need for irrigation or water intake, capable of self-priming;

8: With good performance, large particles such as impurities and mud can pass through effortlessly;

9: According to different media, the diaphragm is divided into chloroprene rubber, fluororubber, nitrile rubber, and tetrafluoroethylene, which can fully meet the needs of different users. Overcurrent components can also be divided into stainless steel, rubber lined, and aluminum alloy according to user requirements, and machines are divided into ordinary and explosion-proof types.
