Generally, the anti-drain back valve have the form of a rubber membrane adjoining the inner side of the can type filter cover. The membrane covers the holes where the contaminated oil gets through to the filter and protects from the back flow after the engine stops. The anti-drain back valve reduces the dry friction or mitigated solid friction time between working parts of the engine as protecting from the oil flow towards the pump and accelerates the oil flow into the working elements during the engine start, especially after a long break. The position the filter is screwed into the engine, conditions the valve application. If the filter works in the "cover up" position as shown in the picture below, the function of the valve is taken successfully by the gravitation. A valve is required when the filter in screwed in from the side or from the top of the engine body.
With the avantages of being compact in structure, Simple in operation, Convenient in maintanance and low in application cost, The series are new necessary products used in power mining enterprises, Especially when their oil are used in electric equipments, Such as transformer, Mutual inductor and switch. The purifier can remove free water, Free air and particulate contamination, And can make the filtered oil reach or be closed to the standard of the new oil. The product could also be operated together with BJ series to treat aging and waste oil, So it is assistant without doult. Features of Product 1. Simple in operation, Convenient in moving and high efficient in oil treatment. 2. As the new technology, Vacuum- Segregating (Patent No. ZL200420061085. 6) employs particular spinning disk and stainless steel machine with dehydration and air pump and enlarges the area of segregating and coming to three- Dimensional evaporation so that obtain the enough time to boil away. In this way purifier could achieve the best effect. 3. Using new type of heating equipment (Patent No. ZL02276238. 8), It can reduce heating burthen and extend oil life. 4. Oil level control adopt photoelectric way which the main components is imported from Switzerland and have features of sensitive control, Exactitude so much as feel the spume of oil. Spurting oil phenomena is never appeared. 5. With advantages of no leakage, Low noise and long using life, This series of products adopt special input- Oil pump which be airproofed by our factory. 6. In order to meet customer's needs of choosing right filter, We have scientific design and exact filter assemblies which could exchange by ones abroad. Both cost and oil disposal effect are good.

Can type oil filters are used mainly for filtering oil in I.C engines. However, in modern engines these filters are less popular. Previously important advantages such as good resistance to damage and easy replacement of used filters, practically with no risk of oil system contamination are not the priority anymore. Presently the ecological aspects, especially easy filters utilization are more important. In this respect, modern filter cartridges installed in dismountable casings are better. Appearance of can type oil filters is very similar, but the internal construction may vary significantly. Both, the exploitation parameters and construction features for this group of filters must be optimally selected, to assure efficient operation in the engine oil system. Special attention should be paid to valves inside the filter as they are responsible for proper performance of the filter in oil systems. The can type oil filters may contain three types of valves with functions described in details later.
