Discharge any compressed air from the system, and pay enough attention to possible water leakage and leakage of electricity. When starting or restarting a machine or device that incorporates pneumatic components, make sure that the system safety, such as pop-out prevention measures, is secured. Observe warnings and cautions on the pages below to prevent accidents. The safety cautions are ranked as "DANGER", "" and "" in this section. DANGER: : : When a dangerous situation may occur if handling is mistaken leading to fatal or serious injuries, or when there is a high degree of emergency to a warning. When a dangerous situation may occur if handling is mistaken leading to fatal or serious injuries. When a dangerous situation may occur if handling is mistaken leading to minor injuries or physical damage. Note that some items described as "" may lead to serious results depending on the situation. In any case, important information that must be observed is explained. Intro3
1. Confirming specifications Use within the product's specified specification range. Products in this catalog are for use only in a compressed air system. Use with pressure or temperature exceeding the specification range may result in damage or operation faults. (Refer to specifications.) Contact CKD when using for fluids other than compressed air. 2. Safety design Always take necessary measures to prevent harm to operators or objects should this product fail. Familiarize yourself with the use of compressed air before designing the pneumatic circuit. The same functions as mechanical, hydraulic, and electrical methods cannot be anticipated if instantaneous service interruption and holding are required during an emergency stop. Pop-out, air discharge, or leakage due to air compression and expansion could occur. Design the circuit so that compressed air in the system can be discharged. Decide the method of lubricating pneumatic components, and provide correct maintenance. Decide whether to use lubrication or oilless, and provide proper lubricant control. Check leakage current to prevent malfunctions caused by current leaking from other control devices. Note that when using a PLC, etc., leakage current could result in malfunctions. 3. Design for applications Small leakage that do not affect performance are tolerated because this product is used with compressed air. Contact CKD Sales when no leaks are permissible. Design & Selection 4. Working environment Avoid installing this product where it will be exposed to rain, water, or direct sunlight. Do not use this product in a corrosive environment. Use in such an environment could lead to damage or operation faults. Consult with CKD Sales if ozone is generated in supply air. (An ozone-resistant series is available.) If ambient temperature is less than 5 C, moisture in the circuit could freeze and lead to operation faults, etc. Remove moisture to prevent freezing. Avoid using this product in environments were ozone is generated. Confirm that the product will withstand the working environment. This product cannot be used in environments where functional obstacles could occur. Such environments include those reaching high temperatures, having a chemical atmosphere, or involving the presence of chemicals, vibration, humidity, moisture, coolant, or gas or where ozone is generated. 5. Securing space Ensure space around the pneumatic component for installation, removal, wiring, and piping work. 6. Stipulation in instruction manuals Indicate the maintenance conditions in the device's instruction manual. The product's function can drop markedly with working status, working environment, and maintenance, and can prevent safety from being attained. With correct maintenance, the product functions can be used to the fullest. Inch/NPT specifications Vacuum related components Intro4
Inch/NPT specifications Vacuum related components 1. Installation Do not remove the pneumatic component package or the piping port prptecting cap until just before piping the product. If the piping port cap is removed from the piping port before piping work is started, foreign matter could enter the pneumatic component from the piping port and result in faults or faulty operation. Do not install pneumatic components with a method that supports with pipes. Do not remove the dust-proof seal on the piping port until just before piping the product. If the seal is removed from the piping port before piping work is started, foreign matter could enter and result in faults or faulty operation. 2. Pre-operation confirmations After connecting piping, check pipe connections for air leaks before supplying compressed air. Apply a leakage detection agent on pipe connections with a brush, and check for air leaks. Check that that the leak detection agent does not get on the plastic bowl because the plastic bowl could break and cause a hazard. 3. Piping When connecting pipes, wrap sealing tape in the opposite direction from threads starting 2 mm inside from the end of piping threads. If sealing tape protrudes from pipe threads, it could be cut when screwed in. This could cause the tape to enter the solenoid valve and lead to faults. When using a liquid sealant, check that that it does not adhere to the plastic bowl, because it could damage the plastic bowl and cause a hazard. Check that that the pipe connected to the pneumatic component is not dislocated due to vibration, loosening, or pulling. Piping dislocation generates a hazardous state. Observe the following precautions when using nylon tubes or urethane tubes for piping material. Use a flame resistance tube or steel pipe when using in an environment where spatter could scatter. Use a hydraulic hose when piping is to be used for hydraulic pressure. Installation & Adjustment When using the standard push in joint on the spiral tube, fix the base of the tube with a hose band. The tube could rotate and reduce holding performance. Use a spigot joint for high-temperature fluid. Push-in joints cannot be used. Pipe so that piping connection does not deviate by the device's movement, vibration, tension, etc. Always flush just before piping pneumatic component. Substance entering during piping must not enter pneumatic components. Tighten pipes with the appropriate torque. Pipes must be connected with the appropriate torque to prevent air leakages and screw damage. First tighten the screw by hand to prevent damage to screw threads, then use a tool. [Recommended value] Set screw M3 M5 Rc1/8 Rc1/4 Rc3/8 Rc1/2 Rc3/4 Rc1 Tightening torque N m 0.3 to 0.6 1 to 1.5 3 to 5 6 to 8 13 to 15 16 to 18 19 to 40 41 to 70 4. Pneumatic pressure source Install a pneumatic filter just before the circuit used for the pneumatic component. When supplying compressed air for the first time after connecting pipes, do not apply high pressure suddenly. Piping connection could be dislocated or the piping tube fly off, leading to accidents. Caution: If compressed air is supplied too slowly, sealing pressure may not be generated by the sealing mechanism in the solenoid valve. This can lead to air leakage. Air quality Use a CKD clean air system as designated for the application. Use compressed air that does not contain oxidized oil, tar, carbon, etc., from the air compressor. Use compressed air that does not contain solid substance. Intro1
During use & Maintenance 2. Maintenance and inspection 1. Disassembly and assembly Before servicing the product, turn power OFF, stop the compressed air supply, and check that The pneumatic component must be disassembled there is no residual pressure. and assembled by a qualified worker. This is a requirement for ensuring safety. Personnel involved in this step must have passed the Pneumatic Pressure Skill Test Class 2 or higher. Read the relevant product instruction manual thoroughly and fully familiarize yourself with work before disassembling or assembling the pneumatic component. Personnel must be fully familiar with pneumatic component structure and operational principles and safety requirements. Vacuum related components Inch/NPT specifications Intro6
