Selection principle


1. Corrosive medium: Plastic solenoid valve and all stainless steel should be used; for strong corrosive medium, the isolation diaphragm type must be used. For neutral media, a solenoid valve with a copper alloy as the valve housing material should also be used, otherwise, rust debris will often fall off the valve housing, especially in occasions where the action is not frequent. The valve for ammonia cannot be made of copper.

2. Explosive environment: products of corresponding explosion-proof grade must be selected, and waterproof and dust-proof products should be selected for outdoor installation or dusty occasions.

3. The nominal pressure of the solenoid valve should exceed the highest working pressure in the pipe.


1. Medium characteristics

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

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

3) Medium viscosity, usually below 50cSt. If it exceeds this value, if the diameter is greater than 15mm, use a multifunctional solenoid valve; if the diameter is less than 15mm, use a high viscosity solenoid valve.

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

5) If the medium circulates directionally and does not allow backflow, bidirectional circulation is required;

6) The temperature of the medium should be selected within the allowable range of the solenoid valve.

2. Pipeline parameters

1) Choose valve port and model according to medium flow requirements and pipe connection mode;

2) Select the nominal diameter according to the flow rate and the valve Kv value, and the same pipe inner diameter can also be selected;

3) Working pressure difference: if the minimum working pressure difference is above 0.04Mpa, the indirect pilot type can be selected; if the minimum working pressure difference is close to or less than zero, the direct-acting type or the step wise direct type must be selected.

3. Environmental conditions

1) The maximum and minimum temperature of the environment should be selected within the allowable range;

2) In the environment where the relative humidity is high and there are water drops and rain, etc., the waterproof solenoid valve should be selected;

3) Special varieties should be selected for occasions where there are frequent vibrations, bumps and shocks in the environment, such as marine solenoid valves;

4) For use in corrosive or explosive environments, the corrosion-resistant type should be selected first according to the safety requirements;

5) If the environmental space is restricted, a multi functional solenoid valve should be used, because it saves the bypass and three manual valves and is convenient for online maintenance.

4. Power conditions

1) According to the type of power supply, select AC and DC solenoid valves respectively. Generally speaking, AC power is easy to access;

2) For voltage specifications, choose AC220V.DC24V as priority;

3) The power supply voltage fluctuation is usually +%10%.-15% for AC, and DC allows about ±%10. If it is out of tolerance, voltage stabilization measures must be taken;

4) The rated current and power consumption should be selected according to the power supply capacity. It should be noted that the VA value is higher when the AC starts, and the indirect pilot solenoid valve should be preferred when the capacity is insufficient.

5. Control accuracy

1) Ordinary solenoid valves have only two positions, open and closed, and multi-position solenoid valves are required when the control accuracy is high and the parameters are stable;

2) Action time: refers to the time from when the electrical signal is switched on or off to the completion of the main valve action;

3) Leakage: The leakage value given on the sample is a common economic grade.
