|Humat Inc. is the creator and manufacturer of the Humat 4-way Hydrant Valve,
used by innovative fire departments and fire training schools across the USA
and around the world as the most efficient method to get the most water on the
fire ground in the least amount of time.
Valves are made of lightweight aluminum alloy for easy handling, heat treated for
extra strength and hard coated to prevent corrosion and to increase surface
strength. Incredibly durable and designed for ease-of-use, Humat valves provide
an exceptional return-on-investment to fire departments regardless of size.

Rugged, Dependable 4-Way Hydrant Valves
|There is No Next Generation Humat
Valve: In the past another company has
come out with a hydrant valve and says
"The Next Generation Humat Valve is
here!" This is false. There is no next
generation Humat Valve; a next generation
is not necessary. The Humat Valve has
proven to be the easiest-to-use, most
efficient way to get the maximum
amount of water on the fire in the least
amount of time. The Humat Valve has
demonstrated this over many years and is
still doing the same fine job today.

Dear Captain Crawford
My name is Hurley Matthews and I am a retired fire officer. I am also one of the two
patent holders on the Humat 4way Hydrant Valve. I believe this qualifies me to
enlighten you about hydrant valves even if somewhat biased.
In your video on You Tube, you stated that the Humat is the "old" valve when in
actuality, the "new" hydrasist has been in production in Europe longer than the
Humat valve. I think you know it's imported.
Your comparison of water way size in the valves is correct if you have the 5"
hydrasist, but you don't point out that the Humat valve has supplied initial fire ground
operations more than satisfactorily with its "two 90 degree turns" from the beginning
and still does today. It was designed to have the fittings changeable to suit
individual departments needs.
You failed to point out that the hydrasist valve is the larger of the valves in physical
size which makes it more difficult to mount and use.
The one big factor in the difference between that valves is Humat's water way
configuration when pumping water on a large fire when you want all the water that
hydrant will give you. In pump mode, the water is directed straight through and has a
proven capacity of in excess of two thousand gallons per minute with 5" couplings.
The hydrasist, in pump mode is just the opposite with two 90 degree turns with
associated turbulence and friction loss.
Another item to think about is the possibility that the hydrasist can flip upside down
with its operating handle underneath. I admit that is not likely, but charging large
diameter hose can cause the hose and then the appliance to twist. That may require
the operator to lay in the gutter to figure out how to turn the valve to pump mode. Our
Humat valve's operating handle is always on the side no matter which way you lay
This point brings up another advantage Humat has. The Humat always put the
initial line down the gutter no matter which way you lay out. This allows easy
placement of the engine that is assigned to pump the hydrant gutter line which the
hydrasist makes difficult by placing the initial line out in the road to bend towards that
fire. This placement also increases the chance of traffic damage by the hose being
out in the road.
One more item to consider is that the Humat valve automatically changes over to
pump mode when the pumping engines operator opens the discharge valve on the
engine and exceeds the current hydrant pressure. This allows the operation without
the operator going to the valve. If the pumping engine should fail for any reason, the
Humat valve will revert to hydrant pressure in the gutter line automatically. With the
hyydrasist, one must physically turn the valves operating handle for these two
There is another new addition to the 4way hydrant valve market that appeared
during the summer of 2010. It is the Task Force Tips "Oasis Hydrant Assist Valve"
and we at Humat invite you to look it over. We think you will find it is similar to a
hydrasist valve with a gear reduction operated crank type operating handle. You will
also find a useless clapper position indicator.
I sincerely hope you reconsider the attributes of the hydrasist valve.
Thank you for your attention.
This is a rebuttal to a video posted on you tube by the City of Miami Dept. of
Fire & Rescue
Keep in mind that the Humat 4-way Hydrant Valve is the simplest to use and
maintain appliance available today. We offer these words to help those of you who
must write your departments technical directives.
The one big advantage in the Humat valve is Humat’s water way configuration and
size. When pumping water on a large fire when you want all the water that hydrant
will give you, the Humat valve will never limit the amount of water available from the
hydrant. The butterfly controlled waterway that directs water to the engine is a full 5
½ inches in diameter. In pump mode, the water is directed from the engine straight
through a 4 inch unencumbered waterway and has a proven capacity of in excess of
two thousand gallons per minute with no measurable pressure loss due to friction.
The Humat Valve’s compact size allows easier carrying and mounting.
The Humat valve is not subject to twisting from the charging of large diameter hose;
other valves on the market can flip upside down due to the torque of the attached
hose to the valve when the hose is pressurized. This can be a very serious problem
with valves other than the Humat in that their operating instructions will be visible only
from the ground looking up. The operating handle of the Humat, whether up side
down or right side up is easily accessible. The operating handle is always on the
side no matter which way you lay out. The handle position is an immediately
recognizable indication of the position of the controlling butterfly valve, if the handle
is across the valve it is closed if in line with the valve the valve is open.
This point brings up another advantage Humat has. The Humat always puts the
initial line down the street parallel to the gutter no matter which way you lay out. This
allows easy placement of the engine that is assigned to pump the hydrant gutter line,
without the danger of blocking the passage of other equipment or apparatus going
down the street or errant traffic damage.
One more item to consider is that unlike the other valves the Humat valve
automatically changes over to pump mode when the pumping engines operator
opens the discharge valve on the engine and exceeds the current residual hydrant
pressure. This allows the operation without the operator going to the valve. If the
pumping engine should fail for any reason, the Humat valve will automatically revert
to hydrant pressure in the gutter line.
Another point with the Humat valve is that all maintenance can be done in your
station using ordinary tools. Most all parts can be shipped to you within 24 hours of
receiving your order.
The Humat can be delivered with any combination of screw threads or quick
disconnect couplings such as Storz couplings. All couplings are bolted on and not
an integral part of the valve; the valve is never obsolete. This is important should
your fire company decide for any reason to change the size or couplings of the hose
you use, you may select any thread or coupling you desire and not have to purchase
new valves. This adaptability allows one valve type to be used with multiple engine
companies using different hose size loads. This feature simplifies training and
Humat hopes that these points we have made will help in your decision.
