The fluid in the pipeline must be consistent with the medium calibrated in the selected solenoid valve series model.

The temperature of the fluid must be lower than the calibration temperature of the selected solenoid valve.

Electromagnetic valves allow liquid viscosity to generally be below 20CST, and if it exceeds 20CST, it should be noted.

When the working pressure difference and pipeline pressure difference are less than 0.04MPA, direct acting and step-by-step direct acting models such as ZS, 2W, ZQDF, ZCM series from Ningbo Aierpake Company should be selected; When the working pressure difference is greater than 0.04MPA, a pilot operated (pressure difference) solenoid valve can be selected; The pressure difference should be less than the calibration pressure of the solenoid valve; Generally, solenoid valves work in a one-way manner, so attention should be paid to whether there is a reverse pressure difference, and if a check valve is installed.

Pay attention to the flow aperture and pipe diameter; Electromagnetic valves are generally only controlled by a switch with two positions; If conditions permit, please install a bypass pipe for easy maintenance; When there is water hammer phenomenon, it is necessary to customize the opening and closing time adjustment of the solenoid valve.

Explosion proof solenoid valve is a device that encloses all components that may ignite explosive gas mixtures in a single enclosure. The enclosure can withstand the explosion of flammable mixtures that penetrate into the interior of the enclosure through any joint surface or structural gap without damage, and will not cause the ignition of explosive environments formed by one or more gases or vapors on the outside. The components that may generate sparks, arcs, and dangerous temperatures are placed in an explosion-proof enclosure, which separates the internal space of the device from the surrounding environment.

1. Explosion proof solenoid valves have a long working life.

2. Explosion proof solenoid valve working system: divided into three types: long-term working system, repeated short-term working system, and short-term working system. Explosion proof solenoid valves are all designed for long-term operation, meaning that the coils are allowed to work continuously with electricity. For situations where the valve is open for a long time but only closed for a short time, it is advisable to use a normally open solenoid valve. When used for short-term work and in large quantities, special orders can be made to reduce power consumption.

3. Explosion proof solenoid valve operating frequency: When the operating frequency requirement is high, a direct acting solenoid valve should be preferred for the structure, and AC power should be preferred for the power supply.
