How to choose the appropriate solenoid valve coil introduction

Solenoid valves are essential in everyday life, so how can we choose the right solenoid valve? The choice of solenoid valves requires four principles: safety, economy, suitability and reliability. First of all to ensure its safety, but also economical and practical, all kinds of encroachment should be appropriate, if the temperature of the medium is not suitable, the solenoid valve coil will burn, the seal will also age, affecting the service life, working life, working frequency, etc. Requirements must be reliable.

1. Pipeline parameters, diameter specifications, should be selected according to the inner diameter of the pipe or the flow rate; the interface mode is determined by itself.
2. Fluid parameters, different fluids should choose different materials. For example, corrosive fluids should choose corrosion-resistant solenoid valves, and some special ones should choose high-viscosity solenoid valves.
3. Pressure parameters, different working pressures, sometimes choose direct-acting type, sometimes choose pilot type, as for nominal pressure, it depends on the formula.
4. Electrical selection, it is more convenient to choose AC220V and DC24 specifications as much as possible.
5. The length of continuous working time, if the solenoid valve is open for a long time, and the opening time is longer than the closing time, it is best to choose the normally open type. If the opening time is not long, the normally closed type is selected, and some need In the case of security protection, choose a long-term power-on type.
6. Environmental requirements, some require auxiliary functions, such as waterproof, explosion-proof, etc.
