5.0 Ma ilot Operated /3 ort Solenoid Valves & Check Valves recautions 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 energization The solenoid coil will generate heat when continuously energized. Avoid using in a tightly shut container. Install it in a wellventilated area. Furthermore, do not touch it while it is being energized or right after it is energized. 3. This solenoid valve cannot be used for explosion proof applications. 4. Maintenance space The installation should allow sufficient space for maintenance activities. 5. 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. 6. Use caution regarding exhaust port freezing. If a high pressure air (more than.0 Ma) is quickly exhausted, there may be an occurrence in which the valve will not switch properly or the service life will substantially decrease due to condensation or freezing caused by the substantial temperature change. When condensation or freezing occurs, take measures such as using a freeze-reducing silencer (VCHNF series), etc. 7. Use caution regarding back pressure. ) When port 3 (EXH) of a 3 port solenoid valve (VCH400 series) is excessively throttled or used as a selector valve (pressurizing, 3 port), the pressure in the port should be within a range of half the pressure in port (port pressure = > twice as strong as port 3 pressure). Using a 3 port valve beyond its back pressure and/or supply pressure range may cause the valve switch to malfunction or result in unstable operation. ) In the case of a 3 port solenoid valve, when the valve is being switched, a high pressure air will be introduced into the lower pressure side. Therefore, when using this product as a selector valve for switching a high and medium pressure, a relief type regulator (VCHR series) must be used for the medium pressure side. 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 catalog.. Fluid Corrosive gas Cannot be used since it will lead to cracks by stress corrosion or result in other incidents. 3. Air quality ) Use clean air. Do 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. A filtration degree of 5 µm 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 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 Best neumatics No. 5 for further details on compressed air quality. 4. Ambient environment Use within the operable ambient temperature range. Confirm the compatibility between the product s composition materials and the ambient atmosphere. Be sure that the fluid used does not touch the external surface of the product. 5. Supply source If the primary side air is throttled, flow may be reduced resulting in the malfunction of the switch or instability in the response time because of the pilot operated solenoid valve. Conduct piping work suited for the secondary side piping (air consumption). Also, when a regulator is installed, the air supply will stop right after the solenoid valve is switched due to the response time of the regulator. Thus, when using it below the minimum operating pressure, adjust the pipe size, length or provide an air tank, etc. 368

Leakage voltage articularly 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. ower supply Switching element C OFF R Leakage current Leakage voltage Valve AC coil: 0% or less of rated voltage DC coil: % or less of rated voltage Caution iping. reparation 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. Avoid pulling, compressing, or bending the valve body when piping.. Wrapping of pipe tape ipe tape is not necessary since this product uses a pneumatic and hydraulic purpose G thread which conforms to ISO 79-. When an R (taper) thread is used, leave to threads at the tip exposed before winding the piping thread around it 4 to 5 times. Winding direction Warning Mounting. If air leakage increases or 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 force to the coil section. Be sure to apply the wrench to the external part of the piping connection. (Hexagonal parts or width across flats) Also, use caution when mounting a silencer or piping to the VCH40 series 3 port solenoid valve because the top (G/4) is a pilot exhaust port. 3. Be 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. 4. Avoid sources of vibration, or adjust the arm from the body to the minimum length so that resonance will not occur. Expose approx. threads Connecting a R thread ipe tape (Winding the pipe tape 4 to 5 times) 3. Always tighten threads with the proper tightening torque. VCH When attaching fittings to valves, tighten with the proper tightening torque shown below.

5.0 Ma ilot Operated /3 ort Solenoid Valves & Check Valves recautions 3 Be sure to read this before handling. Caution Wiring. As a rule, use electrical wire with a cross sectional area of 0.5 to.5 mm for wiring. Furthermore, do not allow excessive force to be applied to the lines.. Use electrical circuits which do not generate chattering in their contacts. 3. Use voltage which is within ±0% of the rated voltage. In cases with a DC 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 absorber, etc., in parallel with the solenoid. Or, adopt an option that comes with the surge voltage protection circuit. (However, a surge voltage occurs even if the surge voltage protection circuit is used. For details, please consult with us.)
