Leakage is refers to the leak of stem packing place, in the mouth of the gasket leaking caused by casting defects of leaking, and the valve body. No leakage is allowed. 4) Electromagnetic valve main advantage is small size, reliable operation, convenient maintenance, cheap. When the choice need to pay attention to choose according to the technological requirements normally open or normally closed type.
