11 5.0 MPa Pilot Operated /3 Port Solenoid Valves & Check Valves Precautions Be sure to read this before handling the products. 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 ill generate heat hen continuously energized. Avoid using in a tightly shut container. Install it in a ellventilated area. Furthermore, do not touch it hile 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 allo 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 MPa) is quickly exhausted, there may be an occurrence in hich the valve ill not sitch properly or the service life ill 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 ithin a range of half the pressure in port (port pressure = > tice as strong as port 3 pressure). Using a 3 port valve beyond its back pressure and/or supply pressure range may cause the valve sitch to malfunction or result in unstable operation. ) In the case of a 3 port solenoid valve, hen the valve is being sitched, a high pressure air ill be introduced into the loer pressure side. Therefore, hen using this product as a selector valve for sitching 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 ithin the operating ranges specified in this catalog.. Fluid Corrosive gas Cannot be used since it ill lead to cracks by stress corrosion or result in other incidents. 3. Air quality ) Use clean air. Do not use compressed air hich 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 poder is generated, eliminate it by installing mist separators at the upstream side of valves. If excessive carbon poder is generated by the compressor, it may adhere to the inside of the valves and cause a malfunction. Refer to Best Pneumatics No. 6 for further details on com- pressed air quality. 4. Ambient environment Use ithin the operable ambient temperature range. Confirm the compatibility beteen the product s composition materials SX0 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, flo may be reduced resulting LVM in the malfunction of the sitch or instability in the response time because of the pilot operated solenoid valve. Conduct piping ork suited for the secondary side piping (air consumption). Also, hen a regulator is installed, the air supply ill stop right after the solenoid valve is sitched due to the response time of the regulator. Thus, hen using it belo the minimum operating pressure, adjust the pipe size, length or provide an air tank, etc. 44

12 5.0 MPa Pilot Operated /3 Port Solenoid Valves & Check Valves Precautions Be sure to read this before handling the products. Selection Caution. Leakage voltage When the solenoid valve is operated using the controller, etc., the leakage voltage should be the product alloable leakage voltage or less. Particularly hen using a resistor in parallel ith a sitching element and using a C-R element (surge voltage suppressor) to protect the sitching element, take note that leakage current ill flo through the resistor, C-R element, etc., creating a possible danger that the valve may not turn off. Poer supply Sitching 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 Piping. Preparation before piping Before piping is connected, it should be thoroughly blon out ith air (flushing) or ashed to remove chips, cutting oil and other debris from inside the pipe. Avoid pulling, compressing, or bending the valve body hen piping.. Winding of sealaut tape Pipe tape is not necessary since this product uses a pneumatic and hydraulic purpose G thread hich conforms to ISO 79-. When an R (taper) thread is used, leave to threads at the tip exposed before inding the piping thread around it 4 to 5 times. Winding direction Expose approx. threads Sealaut tape (Winding the pipe tape 4 to 5 times) 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 rench to the external part of the piping connection. (Hexagonal parts or idth across flats) Also, use caution hen 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 donards. When mounting a valve ith its coil positioned donards, foreign objects in the fluid ill 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 ill not occur. Connecting a R thread 3. Alays tighten threads ith the proper tightening torque. When attaching fittings to valves, tighten ith the proper tightening torque shon belo. Tightening Torque for Piping Connection threads Proper tightening torque N m G, Rc / 8 to 30 G, Rc 3/4 8 to 30 G, Rc 36 to Connection of piping to products When connecting piping to a product, refer to its operation manual to avoid mistakes regarding the supply port, etc. Port : Supply port Port : Output port Port 3: Exhaust port Note) Supply port hen used as a selector valve. Hoever, use ithin the range of the port pressure > = port 3 pressure x ( times). 44

13 5.0 MPa Pilot Operated /3 Port Solenoid Valves & Check Valves Precautions 3 Be sure to read this before handling the products. Caution Wiring. As a rule, use electrical ire ith a cross sectional area of 0.5 to.5 mm for iring. Furthermore, do not allo excessive force to be applied to the lines.. Use electrical circuits hich do not generate chattering in their contacts. 3. Use voltage hich is ithin ±0% of the rated voltage. In cases ith a DC poer supply here importance is placed on responsiveness, stay ithin ±5% of the rated value. The voltage drop is the value in the lead ire section connecting the coil. 4. When a surge from the solenoid affects the electrical circuitry, install a surge absorber, etc., in parallel ith the solenoid. Or, adopt an option that comes ith the surge voltage protection circuit. (Hoever, a surge voltage occurs even if the surge voltage protection circuit is used. For details, please consult ith us.)
