Basic characteristics of imported high temperature and high pressure solenoid valves
I. safety: if we do not pay attention to safety, disaster will happen.
1. Corrosive medium: Plastic King solenoid valve and stainless steel should be selected; isolation diaphragm type should be selected for the strongly corrosive medium of imported water solenoid valve.
2. Explosive environment: the corresponding explosion-proof grade products must be selected. Waterproof and dust-proof varieties should be selected for outdoor installation or dust-proof occasions.
3. the nominal pressure of solenoid valve should exceed the maximum working pressure in the pipe.
Two. Applicability: does not apply to equal to spend money to buy things, but also add trouble!
Three. Reliability: unreliability will damage the whole system!
1. Working life. This item is not included in the ex-factory test item. The imported flange solenoid valve belongs to the type test item. In order to ensure the quality, we should choose the famous brand products of regular manufacturers.
2, work standard: divided into long term work system, repeated short time work system and short time work system three kinds. The company's regular products are long term work, that is, the coil allows long-term power.
3. Working frequency: When the operating frequency is high, the structure should be preferred to import direct-acting solenoid valves, and the power supply should be preferred to listen to and communicate.
4. Motion reliability
