Warning. annot be used as an emergency shutoff valve, etc. The valves presented in this catalog are not designed for safety applications such as an emergency shutoff valve. If the valves are used in this type of system, other reliable safety assurance measures should also be adopted.. Extended periods of continuous energization The solenoid coil will generate heat when continuously energized. void using in a tightly shut container. Install it in a well-ventilated area. Furthermore, do not touch it while it is being energized or right after it is energized.. This solenoid valve cannot be used for explosion proof applications.. Maintenance space The installation should allow sufficient space for maintenance activities.. Liquid rings In cases with a flowing liquid, provide a by-pass valve in the system to prevent the liquid from entering the liquid seal circuit.. ctuator drive When an actuator, such as a cylinder, is to be driven using a valve, take appropriate measures to prevent potential danger caused by actuator operation. 7. Pressure (including vacuum) holding It is not usable for an application such as holding the pressure (including vacuum) inside of a pressure vessel because air leakage is entailed in a valve. 8. When the conduit type is used as equivalent to an IP enclosure, install a wiring conduit, etc. 9. When an impact, such as water hammer, etc., caused by the rapid pressure fluctuation is applied, the solenoid valve may be damaged. Give an attention to it. Warning ack page esign Selection. onfirm the specifications. Give careful consideration to the operating conditions such as the application, fluid and environment, and use within the operating ranges specified in this catalog.. Fluid. Type of fluid efore using a fluid, confirm whether it is compatible with the materials from each model by referring to the fluids listed in this catalog. Use a fluid with a dynamic viscosity of 0 mm /s or less. If there is something you do not know, please contact us.. Flammable oil, Gas, onfirm the specification for leakage in the interior and/or exterior area. Warning Selection. orrosive gas annot be used since it will lead to cracks by stress corrosion or result in other incidents.. Use an oil-free specification when any oily particle must not enter the passage.. pplicable fluid on the list may not be used depending on the operating condition. Give adequate confirmation, and then determine a model, just because the compatibility list shows the general case.. Fluid quality The use of a fluid which contains foreign matter 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 used to supply water to boilers, substances such as calcium and magnesium which generate hard scale and sludge are included. Since this scale and sludge can cause the valve to malfunction, install water softening equipment, and a filter (strainer) directly upstream from the valve to remove these substances.. ir quality. Use clean air. o not use compressed air which includes chemicals, synthetic oils containing organic solvents, salt or corrosive gases, etc., as it can cause damage or malfunction.. Install air filters. Install air filters close to valves at their upstream side. filtration degree of m or less should be selected.. Install an air dryer or after cooler, etc. ompressed air that includes excessive drainage may cause malfunction of valves and other pneumatic equipment. To prevent this, install an air dryer or after cooler, etc.. If excessive carbon powder is generated, eliminate it by installing mist separators at 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. Refer to SM s est Pneumatics 00 Vol. catalog for further details on compressed air quality.. mbient environment Use within the operable ambient temperature range. onfirm the compatibility between the product s composition materials and the ambient atmosphere. e sure that the fluid used does not touch the external surface of the product.. ountermeasures against static electricity Take measures to prevent static electricity since some fluids can cause static electricity. 7. For the low particle generation specification, confirm us separately. 8. Minimum differential operating pressure Even if the differential pressure is greater than the minimum differential operating pressure when the valve is closed, it may become lower than the minimum differential operating pressure when the valve is open due to restrictors in the piping of the supply source (such as a pump, compressor, etc.). Please exercise caution.

26 Port Solenoid Valve for Fluid ontrol Precautions e sure to read this before handling. For detailed precautions on each series, refer to the main text. aution. Leakage voltage Particularly when using a resistor in parallel with a switching element and using a -R element (surge voltage suppressor) to protect the switching element, take note that leakage current will flow through the resistor, -R element, etc., creating a possible danger that the valve may not turn off. Power supply Warning Selection Switching element OFF R Leakage current coil: 0% or less of rated voltage coil: % or less of rated voltage Valve. Low temperature operation. The valve can be used in an ambient temperature of between 0 to 0. 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. Mounting Leakage voltage. If air leakage increases or equipment does not operate properly, stop operation. fter mounting is completed, confirm that it has been done correctly by performing a suitable function test.. o not apply external force to the coil section. When tightening is performed, apply a wrench or other tool to the outside of the piping connection parts.. e sure not to position the coil downwards. When mounting a valve with its coil positioned downwards, foreign objects in the fluid will adhere to the iron core leading to a malfunction.. o not warm the coil assembly with a heat insulator, etc. Use tape, heaters, etc., for freeze prevention on the piping and body only. They can cause the coil to burn out.. Secure with brackets, except in the case of steel piping and copper fittings.. void sources of vibration, or adjust the arm from the body to the minimum length so that resonance will not occur. 7. Painting and coating Warnings or specifications printed or labeled on the product should not be erased, removed or covered up. aution Piping. Preparation before piping efore piping is connected, it should be thoroughly blown out with air (flushing) or washed to remove chips, cutting oil and other debris from inside the pipe. Install piping so that it does not apply pulling, pressing, bending or other forces on the valve body.. Wrapping of pipe tape When connecting pipes, fittings, etc., be sure that chips from the pipe threads and sealing material do not enter the valve. Furthermore, when pipe tape is used, leave. to thread ridges exposed at the end of the threads. Winding direction Expose approx. threads Pipe tape. void connecting ground lines to piping, as this may cause electric corrosion of the system..lways tighten threads with the proper tightening torque. When attaching fittings to valves, tighten with the proper tightening torque shown below. Tightening Torque for Piping onnection threads Rc /8 Rc / Rc /8 Rc / Proper tightening torque N m 7 to 9 to to 8 to 0. onnection of piping to products When connecting piping to a product, refer to its instruction manual to avoid mistakes regarding the supply port, etc.. Steam generated in a boiler contains a large amount of drainage. e sure to operate it with a drain trap installed. 7. In applications such as vacuum and non-leak specifications, use caution specifically against the contamination of foreign matters or airtightness of the fittings. 8. If a regulator is directly connected to a solenoid valve, their interaction will cause them to enter a state of resonance. In some cases, this will result in chattering. ack page
