1) The main control parameters of the solenoid valve are the diameter, the design nominal pressure, the allowable temperature range of the medium, and the interface size.

2) Solenoid valves use electromagnets to drive the opening and closing of valves. They are usually used in two-position control with a diameter below 40mm, especially for connecting, cutting off or switching gas and liquid circuits.

3) The sealing performance of the valve is one of the main indicators for evaluating the quality of the valve. The sealing performance of the valve mainly includes two aspects, namely internal leakage and external leakage. Internal leakage refers to the sealing degree of the medium between the valve seat and the closing member. External leakage refers to the leakage of the valve stem packing, the leakage of the gasket of the middle port, and the leakage of the valve body due to casting defects. Leakage is not allowed to happen.

4) The main advantages of solenoid valves are small size, reliable operation, convenient maintenance and cheap price. When choosing, you need to pay attention to choose normally open or normally closed type according to the process requirements.
