AIR RELEASE VALVES
WHY and WHERE to use An Air Release Valve has a small venting orifice and is used wherever
air is entrained in water under pressure. These pockets of air increase the resistance to the flow of water. In critical
installations, air can reduce the capacity of a line down to zero. More common is an increased resistance of 10 to 15%.
The increased resistance must be overcome by the pump using more power than necessary to move the required
amount of water. Such a loss can continue unnoticed for years creating excessive power consumption costs. This is a
major reason why all points where air can collect should be equipped with an APCO Air Release Valve.
HOW TO OPERATE These valves have much smaller orifices than the Air/Vacuum Valves. Their function
is to release small pockets of air which gather at the high points of a system after it is filled and under pressure.
The Air Release Valve has the ability to open against internal pressure because it has a small orifice and a leverage
mechanism which multiplies the force of the float. This force must be greater than the internal pressure across the
orifice in order to open the orifice when a pocket of air needs to be vented. This explains why, as the internal pressure
increases, the orifice decreases in size to facilitate the valve opening.

WHERE TO INSTALL...
TYPICAL PIPELINE AND POSITION OF NECESSARY
AIR VALVES.
Also install on:
1. Centrifugal pumps
2. Hydropneumatic Tanks
3. Enclosed Systems
4. Sewage Lines

AIR/VACUUM VALVE on pump discharge before check valve (not necessary for pumps with positive suction head) or HYDRAULICALLY
CONTROLLED AIR/VACUUM VALVE where a discharge central valve is normally closed during pump start-up to develop head.
NOTE: INSTALLING MANWAYS AT INTERVALS IN LARGER SIZE PIPELINES PROVIDES AN EXCELLENT POINT TO INSTALL AIR VALVES.
