VNB Series Extended periods of continuous energization If a valve is continuously energized for long periods, heat generation of the coil may result in reduced performance and shorter service life. This may also have an adverse effect on the peripheral equipment in proximity.
Therefore, if an air compressor has a small air delivery, the pressure may not be sufficient. Auto Drain Caution M Refrigerant with GWP Reference Global Warming Potential (GWP) Refrigerant The auto drain may not function properly, depending on the quality of the compressed air. Check the operation once a day.
When the handle is rotated with a tool, it may apply excessive torque to the handle or inside the valve body and it may cause damage. Rotate the handle by hand. 9. When locking the valve with LOTO feature in the closed position, use safety lockout hasp. (AP3657, AP4657, AP3157, AP3900) The valve with LOTO feature has a built in LOTO capability.
Rotating the knob excessively may damage internal parts. 2. Rotate the pressure adjustment knob only after unlocking. If rotated while locked, the connecting part between the body and the bonnet may be damaged. 3. For pressure adjustment knob operation, a hexagon wrench can be used in the direction of the pressure increase.
Air leakage may be happened, depending on the position in which a rod seal is fitted.
The period may vary depending on the temperature and other conditions. In some cases the absorber may need to be replaced before the allowable operating cycle above. 1. Use caution not to be exposed to cutting oil, water, or dust, etc.
If there is polarity, incorrect polarity may cause damage to the elements inside the valve or power supply equipment, and malfunction may result. 2. When electric power is connected to the solenoid valve, be careful to apply the proper voltage. Improper voltage may cause a malfunction or the coil to burn out. 3. After completing the wiring, confirm that the connections are correct. 4.
It may not be possible to connect them, or they may cause other trouble, such as air leakage or the tube pulling out after connection. 2. Tubing O.D: 2 Other tube brands cannot be used. It may not be possible to connect them, or they may cause other trouble, such as air leakage or the tube pulling out after connection. 1116
There may be the case it will vary substantially depending on an ambient environment.
There is a possibility that the lock may not be released. (Refer to the section on releasing the lock.) 3. Release the lock when mounting or adjusting the cylinder. If mounting or other work is performed when the cylinder is locked, the lock unit may be damaged. Bore size (mm) Thread size Pulling force Stroke (mm) 4. Operate with a load ratio of 50% or less.
Otherwise, there is a possibility that the lock may not be released. (Refer to the Releasing the Lock section.) 3. Release the lock when mounting or adjusting the cylinder. The lock unit may be damaged if mounting or other work is performed when the cylinder is locked. 4. Operate with a load factor of 50% or less.
If the effective area is smaller, it may encounter an unexpected sudden slide table movement. Install a solenoid valve for braking as close to the cylinder as possible. If there is a long distance between the cylinder and valve, it may cause fluctuations in the stop accuracy or unexpected sudden slide table movements.
The lock may be released due to inflow of the unlocking pressure. 2. Install speed controllers for meter-out control. If it is used in meter-in control, it may result in malfunction. 3. Be careful of reverse exhaust pressure flow from a common exhaust type valve manifold.
(Tolerance 30%) Hysteresis may fluctuate due to the operating environment.
If the SI unit is not assembled properly, inside PCBs may be damaged or liquid and/or dust may enter into the unit.
If the tightening torque is exceeded the mounting screws may be broken. IP67 protection cannot be guaranteed if the screws are not tightened to the specified torque. If a large manifold valve is mounted, lift the unit so that stress is not applied to the connecting part while transporting. The stress may cause breakage of the connecting part.
This may decrease the performance and life expectancy of these parts. In addition, disassembly may cause danger. Torque values specified in this manual must be followed. Not adhering to these specifications, can result in damage to the product. 8 XL-OMV0005 3-2.
Due to the different materials used, changing only the seal may prove inadequate.
