Use a heavy-duty cord with an outside cable diameter of o6 to 12 mm. . Use the tightening torques below for each section. Note) For an outside cable diameter of o9 to 12 mm, remove the internal parts of the rubber seal before using. Caution Maintenance Warning 1. Filters and strainers 1) Be careful regarding clogging of filters and strainers. 2) Replace filter elements after one year of use, or earlier if the pressure drop reaches 0.1 MPa. 3) Clean strainers when the pressure drop reaches 0.1 MPa. 2. Lubrication When using after lubricating, never forget to lubricate continuously. 3. Storage In case of long term storage after use, thoroughly remove all moisture to prevent rust and deterioration of rubber materials, etc. 4. Exhaust the drainage from an air filter periodically. 1. Removing the product The valve will reach a high temperature when used with high temperature fluids. Confirm that the valve temperature has dropped sufficiently before performing work. If touched inadvertently, there is a danger of being burned. 1) Shut off the fluid supply and release the fluid pressure in the system. 2) Shut off the power supply. 3) Remove the product. 2. Low frequency operation Switch valves at least once every 30 days to prevent malfunction. Also, in order to use it under the optimum state, conduct a regular inspection once a half year. Operating Precautions Warning 1. If there is a possibility of reverse pressure being applied to the valve, take countermeasures such as mounting a check valve on the downstream side of the valve. 2. When problems are caused by a water hammer, install water hammer relief equipment (accumulator, etc.), or use an SMC water hammer relief valve (Series VXR). For details, please consult with SMC. Operating Precautions Warning 3. When the pilot type 2 port solenoid valve is closed, and pressure is applied suddenly due to the starting of fluid supply source such as pump and compressor, the valve may open momentarily and fluid may leak. 4.If the product is used in the conditions in which rapid decrease in the inlet pressure of the valve and rapid increase in the outlet pressure of the valve are repeated, excessive stress will be applied to the diaphragm, which causes the diaphragm to be damaged and dropped, leading to the operation failure of the valve. Check the operating conditions before use. Terminal no. DIN terminal 1 + (.) 2 . (+) Rated voltage DC 100 VAC 200 VAC Other AC q Black Blue Red Gray w Red Blue Red Gray Lead wire color .

Do not use in an atmosphere having corrosive gases, chemicals, sea water, water, water vapor, or where there is direct contact with any of these. 2. Do not use in explosive atmospheres. 3. Do not use in locations subject to vibration or impact. 4. Do not use in locations where radiated heat will be received from nearby heat sources. 5. Employ suitable protective measures in locations where there is contact with water droplets, oil or welding spatter, etc. 151 VX2 VXK VXD VXZ VXS VXE VXP VXR VXH VXF2 VX3 VXA A
