Selection. Fluid quality The use of a fluid that contains foreign objects can cause problems such as malfunction and seal failure by promoting wear of the valve seat and armature, and by sticking to the sliding parts of the armature, etc. Install a suitable filter (strainer) immediately upstream from the valve. s a general rule, use 80 to 00 mesh. When using tap water, since substances such as calcium and magnesium which generate hard scale and sludge are included and can cause the valve to malfunction, install water softening equipment and a filter (strainer) right before the valve to remove these substances. 3. ir quality ) Use clean air. o not use compressed air that contains chemicals, synthetic oils including organic solvents, salt or corrosive gases, etc., as it can cause damage or malfunction. ) Install an air filter. Install an air filter close to the valve on the upstream side. filtration degree of 5 µm or less should be selected. 3) Install an aftercooler or air dryer, etc. ompressed air that contains excessive drainage may cause a malfunction of valves and other pneumatic equipment. To prevent this, install an aftercooler or air dryer, etc. 4) If excessive carbon powder is generated, eliminate it by installing a mist separator on the upstream side of valves. If excessive carbon powder is generated by the compressor, it may adhere to the inside of the valves and cause a malfunction.

However, take measures to prevent freezing or solidification of impurities, etc. ) When using valves for water application in cold climates, take appropriate countermeasures to prevent the water from freezing in tubing after cutting the water supply from the pump, by draining the water, etc. When warming by a heater, etc., be careful not to expose the coil portion to a heater. Installation of a dryer, heat retaining of the body is recommended to prevent a freezing condition in which the dew point temperature is high and the ambient temperature is low, and the high flow runs.
