Summarize the key points of solenoid valve selection

Key points of solenoid valve selection:

     1) The main parameters of solenoid valve selection are pipe diameter, design plan pound level, material allowable temperature range, socket specifications, etc.

     2) Two-position three-way solenoid valve The manufacturer's solenoid valve uses a solenoid coil to promote the opening and closing of the valve. It is generally used in two-position operation with specifications below 40mm, especially when it is used to connect, disconnect or change the supply. Gas and liquid circuits, etc.

     3) The sealing performance of the valve is one of the key index values for evaluating the quality of the valve. The key to the sealing performance of the valve includes two levels, namely, air leakage and external leakage.

     Leakage refers to the level of sealing of the material between the high-pressure gate valve and the shut-off parts. External leakage refers to the leakage of the filling material of the valve seat, the leakage of the middle port gasket and the leakage of the oil circuit board due to welding defects. Leakage is not allowed.

     4) The key advantages of solenoid valve are small size, reliable posture, convenient maintenance and low price. When selecting, you must pay attention to selecting the open and closed or normally closed type according to the processing technology regulations.
