The Val-Matic Air Valve sizing program is an

easy to use Windows Computer Program for

locating and sizing Air Valves in Water and

Wastewater applications.

Provided system parameters, airValve® will

calculate system data and develop criteria suchas flow rate due to slope. It will recommend valve

locations, sizes and models and print a valve

schedule with profile for the user. Finally, the

program will save your data for future reference.

Available online for download, or by requesting

a copy, the Val-Matic airValve® Sizing Software

is an indispensible, free resource that allows

engineers to more effectively, and more easily,

design their pipeline.

From the float material to the shape

of the body, Val-Matic Air Valves

are designed for years of reliable

performance. All valves meet AWWA

C512 requirements.

HEAVY DUTYSTAINLESS STEEL

Stainless steel type 316 is the standard of

Water & Wastewater facilities throughout

the world when quality and longevity

count. That is the reason Val-Matic

uses type 316 stainless steel in every

internal component in every Air Valve

we make. From nuts to floats, it's all

you'll find inside Val-Matic Air

Valves. The only exception is the

resilient sealing member. Our

sealing members use a variety of

synthetic compounds to assure a tight seal

from the lowest system pressures to the

valve's maximum rated working pressure.

The float is the heart of an Air Valve. One

pinhole or nick in the float's sealing surface

will cause premature failure. That's why

Val-Matic starts with heavy-duty type 316

stainless steel and uses it exclusively

throughout our line. Val-Matic unconditionally

guarantees all air valve floats.

Providing a quality float is not enough to

assure a good seal every time. When

entering the seat, a damaged or off-center

float will prevent a valve from closing. The

high velocities that Air/Vacuum valves are

exposed to can cause unguided floats to be

violently tossed about from side to side and

continuously thrust against the valve body.

For these reasons, all Val-Matic Air/ Vacuum

Valve floats are center guided.

Center guiding guarantees that the

float approaches the seat at a

90° angle to provide a positive

drop tight seal each time.

Round stainless steel bushings

position the hexagonal guides and

hold them firm. The use of hexagonal

guides in round bushings prevents

binding and allows for self-cleaning

of the bushings.

SEATS

All standard models incorporate a resilient

sealing member which mates to stainless

steel. Air Release Valves have a synthetic

sealing member mounted to the float

linkage mechanism. It closes against a

stainless steel seat mounted in the valve

cover. On Air/Vacuum Valves, the stainless

steel float closes against a synthetic seat

mechanically retained in the body. The

patented resilient seat provides positive shut

off from the lowest system pressure to the

valves rated working pressure.

AIR/VACUUM INLETSAND OUTLETS

When is a two-inch hole smaller than a

two-inch hole? When you buy an Air/Vacuum

valve with inlets and outlets of different

diameters. A two-inch Air/Vacuum Valve with

a one-inch outlet orifice has the effective

capacity of only a one-inch

Air/Vacuum Valve. Put simply,

no one can put more than a

gallon of water in a gallon

container. No one can push

more air through a one-inch

hole than its size is capable of

allowing.

That's why check valve and shut-off valve

manufacturers strive to maintain full pipe

diameter through the valve body. A loss of

efficiency occurs when you restrict flow

through the valve. In the case of an

Air/Vacuum valve, it can lead to serious

consequences if the valve is not capable of

relieving a vacuum condition due to restricted

flow. For this reason, all Val-Matic

Air/Vacuum valve outlets are greater or

equal to the valve's nominal size.

Val-Matic has expertise and experience inproviding global solutions to air related

concerns coupled with quality products.

That is why Val-Matic is the world leader in

air valve technology!

Exclusive Features and Benefits

3/9

Designed to bring together the features of an Air Release

and Air/Vacuum Valve, Combination Air Valves give you the

maximum of pipeline protection and efficiency. For highcapacity venting of air during pipeline filling the

Air/Vacuum feature maximizes your fluids flow area. An

Air/Vacuum valve also forces air back into a system. This

pressurizes the pipeline and avoids a destructive vacuum

that occurs during draining or pipe bursts. Trapped pockets

of air that travel through a pipeline system are exhausted

through Air Release Valves. These pockets collect at high

points and limit your fluids flow rate. That forces your pump

to work harder which increases your cost. Combination

Valves combine the traditional and proven features of both

the Air Release and Air Vacuum valve.
