INSTALLATION AND MAINTENANCE INSTRUCTIONS - ORIGINAL VERSION
AVK GATE- AND SERVICE CONNECTION VALVES FOR GAS
SERIES 02, 03, 06, 36, 38 and 46
Valves are not suitable for fatigue loading, creep conditions, wind and earthquake loading, fire testing, fire hazard environment,
corrosive or erosive service, transporting fluids with abrasive solids.
It is the responsibility of the end user to ensure the integrity of the valve is not adversely affected by the surrounding environ-
ment. If there is any doubt the user must implement checks to monitor the product integrity.
The valves referred to in this document have been categorised in accordance with the Pressure Equipment Directive.

8. OPERATING PRESSURES AND TEMPERATURES
End configuration:
Flanged, weld-ends and screw (service connection valves)
Size Range:
32 mm to 600 mm
Maximum Working Pressure:
Standard PED applications 16 bar
Temperature Range:
-10 °C to +60 °C
End configuration:
PE-ends and PE-ends/flanged combination
Size Range:
32 mm to 400 mm
Maximum Working Pressure:
Standard PED applications 10 bar
Temperature Range:
-10 °C to +20 °C Note: The maximum working temperature is set according to the ISO9080
lifetime requirements for PE pipes, and is therefore not the max. temperature for the valve.
9. PRESSURE/TEMPERATURE RATING
Valves must only be installed in a piping system whose pressure and temperature do not exceed the above ratings.
If system testing will subject the valve to pressures more than the working pressure rating, this should be within the production
test pressure for the valve.
The maximum allowable pressure as specified is for non-shock conditions. Water hammer and impact for example, should be
avoided.
If the limits of use specified in these instructions are exceeded or if the valve is used on applications for which it was not de-
signed, a potential hazard could result.
10. STORAGE AND HANDLING
The valve should be handled and stored in such a way as to always protect the valve from becoming damaged both internally
and externally, either mechanically or by chemical/substance.
If fitted, valve end protectors should not be removed unless necessary to do so for inspection or installation.
If outdoor storage is unavoidable, valves should be supported off the ground and protected by a weatherproof cover.
Rubber components in valves, or provided as spares, should not be exposed to heat or direct sunlight where this can be
avoided, as this accelerates the ageing of the rubber.
The AVK series 36 gate valve with PE ends is packed so the pipe is protected from UV radiation and other risks of damaging
the pipe. If the packaging is undamaged and kept away from direct sunlight (UV radiation) at a temperature below +40°C, then
the storage time is 5 years from the production date of the pipe. If the valve is not protected correctly, the pipe storage time is
2 years according to EN1555-2/EN12007-2.
To avoid storing old valves at your warehouse, we kindly encourage you to make use of the FIFO method (first in, first out).
