Principle of solenoid valve: Its structure mainly consists of a pilot valve and a main valve, and the main valve adopts a rubber sealing structure. When in the constant position, the movable iron core seals the pilot valve port, the pressure inside the valve chamber is balanced, and the main valve port seals the valve. When the coil is energized, electromagnetic force is generated to attract the movable iron core, causing the medium in the main valve chamber to leak out from the pilot valve port, resulting in a pressure difference. The diaphragm or valve cup is quickly lifted, and the main valve port opens, opening the valve. When the coil is powered off, the magnetic field disappears, the movable iron core resets, the pilot valve port is closed, and after the pressure inside the pilot valve and main valve chamber is balanced, the valve returns to the closed position.
Features: The upper limit of the fluid pressure range is relatively high, and it can be installed freely (customized), but it must meet the fluid pressure difference conditions.
Hint:
If the outlet pressure of the solenoid valve is greater than the inlet pressure, the solenoid valve will conduct in the direction, and a check valve should be installed at this time.
2. The solenoid valve can be used as a check valve by removing the coil and installing it in reverse.
3. If there are impurities in the medium, please install a filter screen or filter valve: 30-60 mesh/in
ASCO solenoid valve selection parameter editing
The selection parameters should first follow the four principles of safety, reliability, applicability, and economy. Secondly, the selection should be based on six aspects of on-site conditions (i.e. pipeline parameters, fluid parameters, pressure parameters, electrical parameters, action mode, and special requirements).
ASCO solenoid valve selection criteria:
1. Select the solenoid valve based on pipeline parameters: diameter specification (i.e. DN), interface method
1) Determine the diameter (DN) size according to the on-site pipeline inner diameter size or flow requirements;
2) Interface method, generally>DN50 requires flange interface, ≤ DN50 can be freely selected according to user needs.
2. Select the material and temperature group of the solenoid valve based on fluid parameters
1) Corrosive fluids: corrosion-resistant solenoid valves and all stainless steel should be selected; Edible ultra clean fluid: It is recommended to use food grade stainless steel solenoid valves;
2) High temperature fluid: It is necessary to choose electromagnetic valves made of high-temperature resistant electrical materials and sealing materials, and to choose piston type structures;
3) Fluid state: up to gaseous, liquid, or mixed state, especially when the diameter is greater than DN25, it must be distinguished;
4) Fluid viscosity: Usually below 50cSt, it can be freely selected. If it exceeds this value, a high viscosity solenoid valve should be used.
3. Selecting solenoid valves based on pressure parameters: principles and structural types
1) Nominal pressure: This parameter has the same meaning as other general valves and is determined based on the nominal pressure of the pipeline;
2) Work pressure: If the work pressure is low, the principle of direct action or step-by-step direct action must be selected; When the minimum working pressure difference is above 0.04Mpa, direct acting, step-by-step direct acting, and pilot operated can all be selected.
4. Electrical selection: The voltage specifications should preferably be AC220V or DC24, which are more convenient.
5. Choose based on the duration of continuous work: normally closed, normally open, or continuously powered on
1) When the solenoid valve needs to be opened for a long time and the duration exceeds the closing time, the normally open type should be selected;
2) If the opening time is short or the opening and closing time is not long, choose the normally closed type;
3) However, for some working conditions used for safety protection, such as furnace and kiln flame monitoring, the normally open type cannot be selected, and the long-term electrified type should be selected. Divided into direct acting, pilot operated, and manual reset valves.
6. Select auxiliary functions according to environmental requirements: explosion-proof, check, manual, waterproof fog, water shower, and diving.

ASCO solenoid valve safety

1. Corrosive media: Plastic king solenoid valves and all stainless steel should be selected; For strongly corrosive media, isolation membrane type must be selected. Neutral media, it is also advisable to use copper alloy as the valve shell material for solenoid valves, otherwise rust debris often falls off from the valve shell, especially in situations where the action is not frequent. Ammonia valves cannot use copper materials.
2. Explosive environment: Corresponding explosion-proof products must be selected, and waterproof and dustproof varieties should be selected for outdoor installation or in dusty environments.
3. The nominal pressure of the solenoid valve should exceed the maximum working pressure inside the pipe.
Applicability:

medium characteristics

1) Select different types of solenoid valves for gas, liquid, or mixed states;
2) Products with different specifications and medium temperatures may cause the coil to burn out and the sealing components to age, seriously affecting their lifespan;
3) The viscosity of the medium is usually below 50cSt. If it exceeds this value and the diameter is greater than 15mm, use a multifunctional 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;
5) If the medium flows in a directional manner and backflow is not allowed, it needs to flow in both directions;
6) The medium temperature should be selected within the allowable range of the solenoid valve.
