Stainless steel vent valves
The vent valve is used to vent air from an enclosed pipe
or vessel and has been specifically designed for the Brewing, Soft Drinks,
Dairy and Food industries.
There are two versions available:
'AE' [Air Escape] which
allows the venting of air from an enclosed pipe or vessel but
automatically closes when liquid fills the valve. A non-return stage is
incorporated to prevent air re-entering through the valve.
'AP' [Air Pass] which
allows air to escape and re-enter. It is typically used for tank venting
or siphon breaking.

Applications
|
|
Venting air from pipework 'AE' (see upper diagram).
Fitting the 'AE' valve just before the pump inlet
(position A) will clear air from the inlet pipe. This will allow the
pump to prime faster and help maintain prime.
Where a non-return valve is installed after the
pump, an 'AE' valve can be fitted in position B so that trapped air
can be vented, thereby allowing the pump to prime.
|
 |
|
Siphon breaking 'AP' (see lower diagram).
Achieved by fitting an 'AP' valve at the highest
point in the system (position C). When the pump is switched off the
siphon action is broken, leaving liquid in the pump ready for the next
operation.
Tank venting 'AP' (see lower diagram).
Fitting an 'AP' valve at the highest point in the
tank (position D) will allow air to escape and to re-enter. |
