2. General operating instructions
- Never attempt to disassemble an actuator.
- 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.
- Do not step on or apply excessive weight on valve. (It can be damaged.)
- Keep the valve away from excessive heat or fire. (It can be damaged, or destroyed.)
- 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 remove a dust-proof cap provided to piping port before piping work starts.
- Be careful of the environment where the valve is installed. In particular, avoid places
exposed to salty wind, corrosive gas, chemical solution, sea water, steam, etc.
- Do not apply a great impact or vibration to the actuator.
(Any such practice may result in breakdown.)
- 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.)
- Do not use the valve in conditions where the fluid may have crystallized.
(The valve will not operate properly.)
- Keep the valve out of direct sunlight, water and dust. Use cover to shield the valve. (The
valve will not operate properly.)
- Be careful not to allow foreign matters, water droplets, oil, and other substances to enter
from the air pipe opening and intake/exhaust hole of the actuator. (In areas that are likely
to have snow, melted water of snow that falls on the valve may enter from the air pipe
opening and intake/exhaust hole of the actuator.)
- Perform periodic maintenance. (Leakage may develop due to temperature changes or
over periods of prolonged storage, rest or operation.)
- When installing the valve, provide an appropriate support. (Failure to do so may cause
breakage due to excessive force applied to the valve body and pipes.)
- The AV valves must be used within the specifications specifically applicable to the product.
(May not work.)
- If the actuator is used in an environment below 5°C temperature, its operating fluid must be
free from the water and moisture contained in it because of possible problems due to the
freeze.
- When you use the valve in a low-temperature environment, put a cover or such that covers
the entire actuator to prevent it from freezing, and check the operating conditions on a
regular basis. (If it freezes, it does not operate normally.)
- Use dehumidified and dust-removed clean operation air. When using highly dry air at a dew
point of -40°C or less, please consult us separately.

11. Installation procedure
- When suspending and supporting a valve, take care and do not stand under a suspended
valve.
- Be sure to conduct a safety check on all hand and power tools to be used before beginning
work.
- When conducting piping work, wear personal protective equipment appropriate to the
contents of work. (Failure to do so may cause an injury.)
- Take care not to over-tighten the Union nut. (The valve can be damaged.)
-Do not use the pipe wrench. (The valve can be damaged.)
- When installing pipes and valves, ensure that they are not subjected to tension,
compression, bending, impact, or other excessive stress.
- When loosening the Union nut on the Carrier side, fix the End connector (hold it with your
hand) and do work. (If the end connector turns, the union will turn together, resulting in the
union and ball separating from the body.)
- If the union is loosened, retighten the union.
- When installing, disassembling, or reassembling the piping, fix the end connector.
- Before a water test, be sure that the Union nut is tightly fastened.
