Installation, Operation & Maintenance
COMBINATION AIR VALVE
MODEL D-060M1 D-060-CM1 D-062M1 D-065M1 D-060L M1
The following is a step-by-step narrated description of the A.R.I. D-060M1 combination air valve installation,
operation and maintenance processes.
The D-060M1 air valve has the features of both an Automatic Air Release valve and an Air & Vacuum valve.
The Air Release component is designed to automatically release small pockets of air to the atmosphere as
they accumulate along a pipeline or piping system when it is full and operating under pressure. The Air &
Vacuum component is designed to automatically discharge or admit large volumes of air during the filling or
draining of a pipeline or piping system. This valve will open to relieve negative pressures whenever water
column separation occurs.

2. INSTALLATION
Important: Before performing any work on the air valve make sure that all workers on site are familiar with
the safety instructions and the relevant local and general safety instructions and work regulations.
2.1. Installation Recommendations
Single Air Valve on an Isolating Valve at 45° to Air Valve outlet
Two Air Valves on an Air Trap with separate Isolating Valves. Air
Valve outlets face outward and the Isolating Valves at 45° to Air
Valve outlets
Two Air Valves on a shared Isolating Valve. Air Valves outlets face
outward and the Isolating Valve at 45° to Air Valve outlets
Underground Installations
Underground installations require a venting pipe from the
manhole
Use an angular installation to bypass an obstacle directly
above the pipeline.

IOM
2.2. Conventions and Measurements
This paragraph presents and explains the terms and
measurements used for the Installation process.
D = Diameter of pipeline
d = diameter of riser
H = Height of riser on the pipeline
(Measured from crown of pipeline)
•For pipelines up to 12" (300mm) in diameter (D), the Air
Trap diameter (d) should be the same as the pipeline
diameter.
•For larger pipelines of up to 60" (1500mm) in diameter
(D), the Air Trap diameter (d) should be 60% of the
pipeline diameter.
•For larger than 60" (1500mm) pipelines (D), the Air Trap
diameter (d) should be 35% of the pipeline diameter.
•The Air Trap length (H) should allow easy access to the air
valve from below and should be at least 6" (150mm).

2.3. Installation Instructions
1. Flush the system before installing the air valve to avoid any debris or sharp objects getting into the air
valve.
2. Carefullyremovetheairvalvefromtheshippingpackage.Unloadallair valvescarefullytoa sturdylevel
surface taking care not to dropthem.
3. Air valves fitted with hoist rings should only be lifted and conveyed using these hoist rings.
4. Install an isolating valve below the air valve, connected by a Riser to the crown of the pipe.
5. Mount the air valve carefully on the rubber gaskets of the isolating valve.
6. Place washers on each of the bolts & nuts that connect the air valve flange to the isolating valve flange.
7. Tighten all the bolts and nuts using the crossover method.
8. The closure tightness of the bolts and nuts shall be according to the standard torque for their specific
size.
9. Use ring wrench keys for the closing and opening of all bolts of the air valve (including the flange bolts).
2.4. Directions for Discharge Outlet
1. Recommended to leave the discharge outlet completely open andunhindered:
2. Avoid directing the discharge outlet opening in the direction of workers, bystanders or animals.
3. Avoid directing the discharge outlet opening in the direction of vulnerable equipment that can be
damaged, such as electrical equipment, unstable structures, etc.

IOM
3. OPERATION
The Air & Vacuum component, with the large orifice, discharges air at high flow rates during the filling of the
system, and admits air into the system, at high flow rates, during system’s drainage and at water column
separation. High velocity air does not blow the float shut. Water lifts the float which seals the valve.
At any time during system operation, if the internal pressure of the system falls below the atmospheric
pressure, air enters the system.
The smooth discharge of air reduces pressure surges and other destructive phenomena.
The intake of air in response to negative pressure protects the system from destructive vacuum conditions,
and prevents damage caused by water column separation. Air entry is essential to efficiently drain the system.
The automatic air release component releases entrapped air in pressurized systems.
As the system starts to fill, the valve functions according to the following stages:
1. Air in the pipeline is discharged by the valve.
2. Liquid enters the valve, lifting the float which pushes the sealing mechanism to its sealing position.
3. Entrapped air, which accumulates at peaks and along the system, rises to the top of the valve, which
in turn displaces the liquid in the valve’s body.
4. The float descends, unsealing the rolling seal. The air release orifice opens and the accumulated air is
released.
5. Liquid enters the valve and the float rises, pushing the rolling seal back to its sealing position.
When the internal pressure falls below the atmospheric pressure (negative pressure):
1. The floats drop down, immediately opening the Air & Vacuum and the air release orifices.
2. Air enters the system.

IOM
4. PERIODIC MAINTENANCE
Please note that the periodic maintenance of the air valve is an integral part of the proper pipeline
maintenance regime; it should be maintained at least once a year in accordance with the quality and
composition of the fluid in the system.
Important: Before performing any work on the air valve, make sure that all workers on site are familiar with the
safety instructions as appear chapter of this document and with all the relevant local and general safety
instructions, standards and work regulations.
4.1. Preparation
Releasing Pressure
Shut the isolating valve located on the riser under the air valve.
Option A:
Using two combination spanners, partially unscrew the bolts connecting the air valve to the riser in order
to release the pressure. Wait till the pressure is released.
Option B. –for air valves with Plug:
Use a ratchet box wrench to gradually release the Plug of the pressure release port, wait till the pressure
is released and then unscrew the Plug completely, remove it and drain the air valve.
The maintenance procedure of the D-060 air valve is divided into the following two separate processes:
Automatic valve
Air & Vacuum valve.
