When the conduit type is used as equivalent to an P65 enclosure, install a wiring conduit etc. ilencer 1. The silencer s response properties do not change in the initial stage, but will change due to the blockage after long use. eplace it after using about 500,000 times. This number is subject to change based on fluid quality and energizing time. 2. When using a silencer, make space for silencer replacement. election 1. ir quality 1. se 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. 2. nstall an air filter. nstall an air filter close to the valve on the upstream side. filtration degree of 5 µm or less should be selected. 3. nstall an aftercooler or air dryer, etc. ompressed air that contains excessive drainage may cause malfunction of valves and other pneumatic equipment. To prevent this, install an aftercooler or air dryer, etc. 4. f excessive carbon powder is generated, eliminate it by installing a mist separator on the upstream side of valves. f excessive carbon powder is generated by the compressor, it may adhere to the inside of the valves and cause a malfunction. efer to the est Pneumatics No. 5 for further details on compressed air quality. 372 Warning aution Power supply witching element election 2. mbient environment se within the allowable ambient temperature range. heck the compatibility between the product s composition materials and the ambient atmosphere. e certain that the fluid used does not touch the external surface of the product. 3. ountermeasures against static electricity Take measures to prevent static electricity since some fluids can cause static electricity. 4. Low temperature operation 1. The valve can be used in fluid temperatures down to 10. owever, 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 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. nstallation 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. 5. luid properties se a general compressed air with a filter of 5 μm or less mounted on the inlet of the piping. (xcluding dry air) 1. Leakage voltage When the solenoid valve is operated using the controller, etc., the leakage voltage should be the product allowable leakage voltage or less. Particularly when using a resistor in parallel with a switching element and using a - element (surge voltage suppressor) to protect the switching element, take note that leakage current will flow through the resistor, - element, etc., creating a possible danger that the valve may not turn off. O Leakage current Leakage voltage coil: 5% or less of rated voltage coil: 2% or less of rated voltage OL. 2. The response performance and start-up speed deteriorate in the case of air operated type (VX2) as compared with a solenoid valve type (VX2). efer to the data for pilot piping. 3. Note that for, idle time and return time increase if the voltage is lowered. f a surge voltage suppressor is installed, the return speed decreases.

38 VX2/VX2 eries pecific Product Precautions 2 e sure to read this before handling the products. efer to back page 50 for afety nstructions and pages 17 to 19 for 2 Port olenoid Valve for luid ontrol Precautions. Warning orrect mounting surface shape Mounting 1. f 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. 2. 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. 3. Mount a valve with its coil position upward, not downward. When mounting a valve with its coil position downward, foreign objects in the fluid will adhere to the iron core leading to a malfunction. specially for strict leakage control, such as with vacuum applications and non-leak specifications, the coil must be positioned upward. 4. o not warm the coil assembly with a heat insulator etc. se tape, heaters, etc., for freeze prevention on the piping and body only. They can cause the coil to burn out. 5. void sources of vibration, or adjust the arm from the body to the minimum length so that resonance will not occur. 6. Painting and coating Warnings or specifications printed or labeled on the product should not be erased, removed or covered up. aution 1. Machine the mounting surface shape so that there are no gaps between the mounting surface and the product. 2 Port olenoid Valve or ust ollector VX2/VX2 eries ncorrect mounting surface shape aution Piping 1. 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. nstall piping so that it does not apply pulling, pressing, bending or other forces on the valve body. 2. void connecting ground lines to piping, as this may cause electric corrosion of the system. 3. 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 thread Proper tightening torque N m c1/4 12 to 14 c3/8 22 to 24 c 28 to 30 c3/4 28 to 30 c1 36 to 38 c1 40 to 42 c2 48 to 50 c2 48 to 50 c3 48 to When connecting piping to a product void mistakes regarding the supply port etc. 5. f a regulator, or a restrictor, is installed immediately before or after the N port of the valve, the main valve may oscillate (chatter). nstall them away from the valve or change the restriction. 6. The header tank capacity should be sufficient. This is a valve for large flow rate, so if the capacity is small, the main valve may oscillate due to pressure drop or insufficient air supply. VX2 VX VX VXZ VX VX VX VXP VX VX VX VX3 VX Warning Piping void gaps 1. uring use, deterioration of the tube or damage to the fittings could cause tubes to come loose from their fittings and thrash about. To prevent uncontrolled tube movement, install protective covers or fasten tubes securely in place. 2. or piping the tube, fix the product securely using the mounting holes so that the product is not in the air. aution Wiring 1. s a rule, use electrical wire with a cross sectional area of 0.5 to 1.25 mm 2 for wiring. urthermore, do not allow excessive force to be applied to the lines. 2. se electrical circuits which do not generate chattering in their contacts. 3. se voltage which is within ±10% of the rated voltage. n cases with a power supply where importance is placed on responsiveness, stay within ±5% of the rated value. The voltage drop is the value in the lead wire section connecting the coil. 4. When a surge from the solenoid affects the electrical circuitry, install a surge voltage suppressor etc. in parallel with the solenoid. Or, adopt an option that comes with the surge voltage protection circuit. (owever, a surge voltage occurs even if the surge voltage protection circuit is used. or details, please consult with M.) 373
