3 port solenoid valve for fluid contro l / precautions 1 be sure to read this before handling. for detailed precautions on each series, refer to the main text. back page 2 1. cannot be used as an emergency shutoff val - ve, etc. the valves presented in this catalogue are not designed for sa - fety applications such as an emergency shutoff valve. if the val - ves are used in this type of system, other reliable safety assu - rance measures should also be adopted. 2. extended periods of continuous energisation the solenoid coil will generate heat when continuously energi - sed. avoid using in a tightly shut container. install it in a well- ventilated area. furthermore, do not touch it while it is being energised or right after it is energised. 3. this solenoid valve cannot be used for explo - sion proof applications. 4. maintenance space the installation should allow sufficient space for maintenance activities (removal of valve, etc.). 5. liquid rings in cases with a flowing liquid, provide a bypass valve in the system to prevent the liquid from entering the liquid seal circuit. 6. actuator 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 lea - kage is entailed in a valve. 8. when the conduit type is used as equivalent to an ip65 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. please pay attention to this. design warning 1. confirm the specifications. give careful consideration to the operating conditions such as the application, fluid and environment, and use within the opera - ting ranges specified in this catalogue. 2. fluid 1) type of fluid before using a fluid, confirm whether it is compatible with the materials from each model by referring to the fluids listed in this catalogue. use a fluid with a kinematic viscosity of 50 mm 2 /s or less. if there is something you do not know, please contact smc. 2) inflammable oil, gas, confirm the specification for leakage in the interior and/or ex - terior area. warning selection 3) corrosive gas cannot be used since it will lead to cracks by stress corrosion or result in other incidents. 4) use an oil-free specification when oil particles must not enter the fluid passage. 5) applicable fluid on the list may not be used depending on the operating condition. just because the compatibility list shows the general case, still give adequate confirmation when selec - ting a model. 3. fluid quality the use of a fluid which contains foreign matter can cause pro - blems 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. as a general rule, use 80 to 100 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. 4. air quality 1) use clean air. do not use compressed air which includes chemicals, synthe - tic oils containing organic solvents, salt or corrosive gases, etc., as it can cause damage or malfunction. 2) install air filters. install air filters close to the valves on their upstream side. a filtration degree of 5 m or less should be selected. 3) install an air dryer or after cooler, etc. compressed 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. 4) if excessive carbon powder is generated, eliminate it by ins - talling mist separators on the upstream side of the valves. if excessive carbon powder is generated by the compressor, it may adhere to the inside of the valves and cause a mal - function. refer to smcs best pneumatics catalogue for further details on compressed air quality. 5. ambient environment use within the operable ambient temperature range. confirm the compatibility between the products composition materials and the ambient atmosphere. be sure that the fluid used does not touch the external surface of the product. 6. countermeasures against static electricity take measures to prevent static electricity since some fluids can cause static electricity. 7. for the low particle generation specification, please contact smc. warning selection
back page 3 3 port solenoid valve for fluid contro l / precautions 2 be sure to read this before handling. for detailed precautions on each series, refer to the main text. 1. if air leakage increases or equipment does not operate properly, stop operation. after mounting is completed, confirm that it has been done co - rrectly by performing a suitable function test. 2. do 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. 3. be sure not to position the coil downwards. when mounting a valve with its coil positioned downwards, fo - reign objects in the fluid will adhere to the iron core leading to a malfunction. 4. do not warm the coil assembly with a heat in - sulator, etc. use tape, heaters, etc., for freeze prevention on the piping and body only. they can cause the coil to burn out. 5. secure with brackets, except in the case of steel piping and copper fittings. 6. avoid 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 labelled on the product should not be erased, removed or covered up. warning caution caution 2. low temperature operation 1. the valve can be used in an ambient temperature of between C10 to C20 c, however take measures to prevent freezing or solidification of impurities, etc. 2. when using valves for water application in cold climates, take appropriate countermeasures to prevent the water from free - zing in tubing after cutting the water supply from the pump, by draining the water, etc. when heating by steam, be care - ful not to expose the coil portion to steam. installation of a dryer or heat retaining of the body is recommended to pre - vent a freezing condition in which the dew point temperature is high and the ambient temperature is low, and the high flow runs. 1. leakage voltage particularly when using a resistor in parallel with a switching element and using a c-r element (surge voltage suppressor) to protect the switching element, take note that leakage current will flow through the resistor, c-r element, etc., creating a pos - sible danger that the valve may not turn off. switching element c off leakage current valve r power supply ac/class b coil: 5% or less of rated voltage ac/class h coil: 20% or less of rated voltage dc coil: 2% or less of rated voltage selection mounting piping leakage voltage 1. preparation before piping before piping is connected, it should be thoroughly blown out with air (flushing) or washed to remove chips, cutting oil and ot - her debris from inside the pipe. 2. 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 1.5 to 2 thread rid - ges exposed at the end of the threads. 3. avoid connecting ground lines to piping, as this may cause electric corrosion of the system . 4. always tighten threads with the proper tighte - ning torque. when attaching fittings to valves, tighten with the proper tighte - ning torque shown below. connection threads rc 1/8 rc 1/4 rc 3/8 rc 1/2 7 to 9 12 to 14 22 to 24 28 to 30 proper tightening torque n ? m tightening torque for piping 5. connection of piping to products when connecting piping to a product, refer to its instruction manual to avoid mistakes regarding the supply port, etc. 6. steam generated in a boiler contains a large amount of drainage. be sure to operate it with a drain trap insta - lled. 7. in applications such as vacuum and non-leak specifications, use caution specifically against the contamination of foreign matters or airtightness of the fittings. winding direction pipe tape expose approx . 2 threads
back page 4 3 port solenoid valve for fluid contro l / precautions 3 be sure to read this before handling. for detailed precautions on each series, refer to the main text. 1. as a rule, use electrical wire with a cross sec - tional area of 0.5 to 1.25m m 2 for wiring. furthermore, do not allow excessive force to be applied to the lines. 2. use electrical circuits which do not generate chattering in their contacts. 3. use voltage which is within 10% of the rated voltage. in cases with a dc power supply where importance is placed on responsive - ness, stay within 5% of the rated value. the voltage drop is the value in the lead wire sec - tion connecting the coil. 4. when a surge from the solenoid affects the electrical circuitry, install a surge absorber, etc., in parallel with the solenoid. or, adopt the option that comes with the sur - ge voltage protection circuit.
