21 VDW / Port Solenoid Valve for Fluid Control Precautions Be sure to read this before handling. Warning Design. Cannot 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 energisation Please consult with SMC when using with energisation for long periods of time.. 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.. This solenoid valve cannot be used for explosion proof applications. 5. Maintenance space The installation should allow sufficient space for maintenance activities (removal of the valve, etc.). Warning Selection. Confirm 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 catalogue.. Fluid temperature Please use within the operating fluid temperature range.. Fluid quality In the case of water The use of a fluid which contains foreign matter can cause malfunction and seal failure. These problems are due to wearing of the valve seat and armature, and sticking to the sliding parts of the armature, etc. Install a suitable filter (strainer) immediately upstream from the valve. In general, a mesh of about 80 to 00 is a guideline for the filter. In the case of air Please use ordinary compressed air where a filter of 0 µm or less is provided on the inlet side piping. (Except dry air) Caution. 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 possible danger that the valve may not turn off. Power supply Switching element OFF C R Leakage current Leakage voltage Valve AC coil 0% or less of rated voltage DC coil % or less of rated voltage. Low temperature operation. Valves can be used from an ambient temperature of -0 C, however, take measures to prevent solidification of impurities or freezing, etc.. When using valves for water applications in cold climates, firstly stop the water supply/discharge of the pump etc., and then take measures to prevent freezing, such as draining water from the piping. When heating by steam, be careful not to expose the coil portion to steam. Also, please take actions to prevent freezing such as heating the body. Back page

22 VDW / Port Solenoid Valve for Fluid Control Precautions Be sure to read this before handling. Warning Mounting. If air leakage increases or the equipment does not operate properly, stop operation. After mounting is completed, confirm that it has been done correctly by performing a suitable function test.. Do not apply external forces to the coil section. When tightening is performed, apply a wrench or other tool to the outside of the piping connection parts.. Do not warm the coil assembly with a heat insulator, etc. Use tape, heaters, etc., to prevent freezing 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. 5. Avoid sources of vibration or adjust the arm from the body to the minimum length so that resonance will not occur. 6. Instruction manual The product should be mounted and operated after the instruction manual is thoroughly read and its contents are understood. Keep the instruction manual where it can be referred to as needed. 7. Painting and coating Warnings or specifications printed or labeled on the product should not be erased, removed or covered up. Caution Piping. Preparation before piping Before 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.. 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.5 to thread ridges exposed at the end of the threads. Winding direction Expose approx. threads Pipe tape. Avoid connecting ground lines to piping, as this may cause electric corrosion of the system.. Always tighten threads with the proper tightening torque. When attaching fittings to valves, tighten with the proper tightening torque shown below. Tightening Torque for Piping Connection threads Proper tightening torque Nm (kgfcm).5 to (5 to 0) Rc /8 7 to 9 (70 to 90) Rc / to (0 to 0) Rc /8 to (0 to 0) Reference Tightening of fitting threads After tightening by hand, tighten approximately /6 turn further with a tightening tool.
