AC 220V 2W250-25 Water Solenoid Valve
Solenoid valves typically have a variety of sealing materials. Typical materials are NBR, EPDM, VITON and PTFE (Teflon). Material selection is highly dependent on the chemistry and temperature of the media. The right choice is critical to ensure long life and optimum valve performance.The advantages of NBR are good resistance to compression, tear and abrasion. Compatible with oils up to 80 ° C, solvent and alcohol. The disadvantages are sensitive to weather effects, moderate temperature resistance, and not suitable for brake fluids and polar solvents.The advantage of VITON is very good overall chemical resistance. The temperature range is between -10 ° C and 120 ° C. Good mechanical properties, resistance to compression and deformation, suitable for high temperature (not suitable for hot water / steam). Good resistance to oils and solvents such as fats, aromatic hydrocarbons and halogenated hydrocarbons, acids, animal and vegetable oils. Not resistant to methanol. The disadvantage is poor tolerance to hot water and steam. At higher temperatures, VITON will swell. Not suitable for polar solvents, certain esters and ethers, glycol based brake fluids.

Application of 2W solenoid valve:
2W Solenoid valve installation steps and routine maintenance:
1. First check whether the solenoid valve is consistent with the selection parameters, such as power supply voltage, medium pressure, differential pressure, etc., especially the power supply. If it is wrong, it will burn the coil. The power supply voltage should meet the rated voltage and voltage fluctuation range: AC +10%~-15%, DC +10%~-10%, and the coil assembly should not be disassembled.
2. Rinse the pipeline before taking over, and remove the metal powder and seal material residue, rust and scale in the pipeline. Pay attention to the cleanliness of the medium. If the medium is mixed with dust and impurities, etc., it will hinder the normal operation of the solenoid valve. The filter or filter should be installed in the pipeline.
3. The electromagnetic coil components of the general solenoid valve should be vertically upright and installed vertically on the pipeline level to the ground. If it is subject to space restrictions or working conditions, it must be installed on the side, and it should be submitted at the time of order selection. Failure to do so may result in the solenoid valve not working properly.
4. Manually cut off the valve before and after the solenoid valve, and bypass should be provided to facilitate the maintenance of the solenoid valve in case of failure.
Common faults and elimination of 2W solenoid valves:
1. The solenoid valve does not work after power-on: check if the power supply wiring is bad → re-wiring and connector connection; check whether the power supply voltage is within the working range - → adjust to the normal position range; check whether the coil is off-welded → re-weld; →Replace the coil; whether the working pressure difference of the imported metering pump is inappropriate → adjust the pressure difference → or replace the proportional solenoid valve; the fluid temperature is too high → replace the proportional solenoid valve; the main valve core and the moving iron core card of the electromagnetic valve Dead → clean, if there is seal damage, replace the seal and install the filter; the viscosity of the liquid is too high, the frequency is too high and the life has reached → replace the product.
2. The solenoid valve can't be closed: the seal of the main spool or the iron core has been damaged → replace the seal; the temperature and viscosity of the fluid are too high → replace the solenoid valve of the opposite port; there is impurity entering the main valve core or moving iron core of the solenoid valve →Clean; spring life has reached or deformed → replaced; throttle hole balance hole blocked → timely cleaning; working frequency is too high or life has reached → re-select product or update product.
3. Other conditions: internal leakage → check whether the seal is damaged, whether the spring is poorly assembled; external leakage → loose connection or seal is broken → tighten the screw or replace the seal; there is noise when energized → the solid part on the head is loose, tighten . The voltage fluctuation is not within the allowable range and the voltage is adjusted. The iron core suction surface is dirty or uneven, and it is cleaned or replaced in time.
