Dramatically Cut
Workload and Cost of Maintenance
The only Foot Valve on the
ground
The reason to choose smolensky foot valve is
the innovative water-stopping, durability and maintenance.
-
The spring and gasket absorb and repel the force of running water to keep water out, which prevents
leakage.*
*Leakage may occur due to foreign objects getting caught in the pipe. In that case, please carry out maintenance from time to time to restore the watertight surface. - The valve with two-point support structure realizes innovative durability and improves water stopping power
- The resistance value is equal to or less than that of a foot valve, so it can be installed at any site where a foot valve is installed. The low resistance allows the pump to perform at its maximum potential.
Do you have any trouble
with General Foot Valve?
-
Because the pump is submerged, it gets stuck and causes water to drain out!
Being submerged, the body of the pump rusts and becomes fixed, therefore resulting in the water draining out.
-
It’s impossible to raise!
Since the ceiling of the pump room is low, it’s hard to raise the valve and put it back in place.
-
Maintenance is time‑consuming!
Maintenance requires several people and an entire day of work. It’s hard to work in the cold for long hours.
-
To prevent water draining, the pump is operated 24‑hours a day!
We are running the pump 24/7 to avoid water drainage but we know that this is a waste of electricity.
The cause of these problems is a check valve attached to the bottom of a suction pipe in the water.
The Best solution is Ground Foot Valve SG. Patented.
The only Foot Valve on the ground.
The streamlined structure achieves
surprisingly low loss, far surpassing
that of a foot valve.
The use of a lift mechanism that supports
the valve at two points provides
overwhelming
durability.
It also has a long life and is economical.
When water is flowing
When the pump is stopped
With the swing type, the valve disc is supported at one point, so the load is
concentrated, resulting in low durability and a short lifespan.
Smolensky foot valve uses a lift type that dramatically distributes the load using two points of support,
the upper and lower guides, and the force of a spring.
It is durable, has a long life and is economical

Product Features of the Ground Foot Valve SG
No need for troublesome lifting work.
Realizing easy maintenance on the ground without tools.
- The valve can be maintained by removing the clamp, greatly improving work efficiency.
- Recovery work after sudden waterfall can be completed quickly and with a small number of people, ensuring high productivity.
- It's economical because you only need to replace maintenance parts that are sold separately.
Made of long-life and highly durable stainless steel, it can be used in a wide range of sites.
The high-performance stainless steel and coating make it suitable for use with seawater and chemical
solutions.

We profited by nearly 4,000,000 Yen

We profited by nearly 4,000,000 Yen
Even though we initially lost a profit of nearly 4 million yen, we bought it because of its ease of maintenance. In nearly two years, we have had no water drainage. Until we went with Smolensky, everything was done manually due to the concern of water drainage. However, now we are running everything by automatic operation. In addition to this, we stopped running the system on Saturdays and Sundays, so we converted the water fee and the electricity bill, and got nearly 4 million yen in profit. I am very satisfied that we were able to regain our investment so soon.

The Cost is Zero Yen
From the point of installing the SG, the trouble of "I cannot drive the pump" is gone. I think there is no other product that meets the needs of facility managers as the SG does. With the original foot valves we were using, on the first day of every New Year, we were constantly working on restoring them. New Years in Japan is a time to relax and I always felt anxious, thinking "We are working on this again", but since we installed the SG, everything is very smooth and our anxiety has been eliminated. The cost is also 0/zero yen when you can do the maintenance yourself.

Seven Units Already Installed
One year has already passed since we installed the Ground Foot Valve SG. At the time of using the conventional foot valve, it was necessary to work on it at least once a month, but since we changed to the SG there has been no drainage due to the entry of dirt or malfunction this year, and the pump constantly supplies water. Even if work is needed, I feel at ease because I know that it can be done without much effort because it is installed on the ground. Since installing the first unit, we were happy with the results so now we have already installed as many as seven units. In the future, we are planning to have internal parts for replacement as spare parts and we plan to be thoroughly prepared.

We Want to Use it for a Long Time
After installing the Ground Foot Valve SG, we have been using it without any troubles such as drainage or leakage. It is also nice to know immediately whether the SG is working, and this is done by simply attaching a vacuum gauge to the suction side. Even when there is trouble, it can easily be maintained on the ground. I am very satisfied. I would like to use it for a long time and plan to do so by replacing the internal parts when necessary.
Answer Your Questions
Q1. It seems impossible to prime the portion below the valve.
How can this
be?
Although there is a layer of air in the piping below the valve, by repeating the ON‑OFF operation and by priming the pump, the water will pass through the system.
1) After foot valve installation
Install the foot valve. The piping, between the water level and the pump, is filled entirely with air. ※１
2) Prime the pump.
Prime the pump by filling the suction piping between the pump and the foot valve with water. ※２
3) Turn the pump ON and then OFF.
Turn on the pump and then turn it off 1‑2 seconds later. This will pull up the water. ※３
Even after the pump stops, the water remains high. There is a layer of air remaining in the piping. ※４
4) Prime the pump again to fill the piping between the pump and the foot valve with water.
Prime the pump to fill the suction piping between the pump and the foot valve with water. ※５
When the pump is powered ON again and then powered OFF, the water is sucked up even more.
Repeat procedures 3) and 4) several times to allow the water to pass through the piping.
Q2. Is it true that drainage will not occur once the water is sucked up?
Using foot valve verification test equipment, we observed the state of the water once it was sucked up.
The Result of our Demonstration Test
The valve was found to hold the water that was drawn for 180 days, without causing any drainage, and then when the pump was restarted, the water flowed smoothly. Just like an experiment with a drinking straw, the valve is stopped with a spring, so no air gets in, and drainage does not occur.
*Be sure to avoid exposure of the end of piping above the liquid surface.
By installing a vacuum gage at the evacuation port, you can visually monitor, on the ground, the condition inside the piping below the valve.
