2. General operating instructions
- Never attempt to disassemble an actuator.
-
Keep hands and other extremities away from moving parts under all circumstances.
(Any such practice may get your hand, arm, or other part of your body caught.)
-
Using a positive-pressure gas with our plastic piping may pose a dangerous condition due to
the repellent force particular to compressible fluids even when the gas is under similar
pressures used for liquids. Therefore, be sure to take the necessary safety precautions such
as covering the piping with protective material. For inquiries, please contact us.
- For conducting a leak test on newly installed piping, be sure to check for leaks under water
pressure. If absolutely necessary to use a gas in testing, please consult your nearest service
station beforehand.
- Before using the product, check the operating power supply and the voltage specification on
the nameplate. Using an improper voltage may cause equipment damage or malfunction.
- Do not step on or apply excessive weight on valve. (It can be damaged.)
- Do not use the valve to fluid containing slurry. (The valve will not operate properly.)
- Do not use AV valves in a place where they may become submerged in water.
- Do not apply a great impact or vibration to the actuator.
- The surface temperature of the actuator may rise during operation. This is due to the heat
generated by the internal equipment and is not a malfunction, but do not use it beyond the
allowable range of ambient temperature of -10 to 55
°
C. (It may cause a malfunction)
- Do not use the valve in conditions where the fluid may have crystallized. (The valve will not
operate properly.)
- Keep the valve away from excessive heat or fire. (It can be damaged, or destroyed.)
- Be careful of the environment where the valve is installed. In particular, avoid places exposed
to salty wind, corrosive gas, chemical solution, seawater, steam, etc.
- Use the valve working pressure, working temperature, ambient temperature within an allowable
range. (The valve can be damaged or deformed by operating beyond the allowable range.)
- Allow sufficient space for maintenance and inspection.
- Select a valve material that is compatible with the media. For chemical resistance information,
refer to “CHEMICAL RESISTANCE ON ASAHI AV VALVE”. (Some chemicals may damage
incompatible valve materials.)
- Keep the valve out of direct sunlight, water and dust. Use cover to shield the valve. (The valve
will not operate properly.)
- Perform periodic maintenance. (Leakage may develop due to temperature changes or over
periods of prolonged storage, rest or operation.)
