Suitable for Citroen Triumph AL4 Transmission Solenoid Valve

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

2) Solenoid valve uses electromagnet to push the valve to open and close, which is usually used in two-position control with a diameter below 40mm, especially for connecting, cutting or switching gas path and liquid path.

3) The sealing performance of the valve is one of the main indexes for evaluating the quality of the valve. The sealing performance of valves 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 part. External leakage refers to the leakage of valve stem packing, middle gasket and valve body caused by casting defects. Leakage is not allowed.

4) The main advantages of solenoid valve are small size, reliable action, convenient maintenance and low price. It is necessary to pay attention to the selection of normally open or normally closed type according to the process requirements.

the medium characteristics

1) Choose different kinds of solenoid valves for gas, liquid or mixed state;

2) Products with different specifications of medium temperature, otherwise the coil will burn and the seal will age, which will seriously affect the service life;

3) The viscosity of the medium is usually below 50cSt. If it exceeds this value, when the diameter is greater than 15mm, use a multi-function solenoid valve; When the diameter is less than 15mm, use a high viscosity solenoid valve.

4) When the cleanliness of the medium is not high, a backwash filter valve should be installed in front of the solenoid valve. When the pressure is low, a direct-acting diaphragm solenoid valve can be selected;
