Float valve level allows you to solve the following tasks:
- maintaining a predetermined upper and lower water limit;
- prevent overflow or lack of fluid.
For specific location the float valve should be selected depending on the design features and the material from which it is made.
Device
The main advantage of a float valve for a container or tank is its independence from electricity.Its design is quite simple, which allows you to carry out its installation yourself, without resorting to the services of specialists.
The tank float valve is constructed of parts such as:
- float - a floating part that responds to a change in the amount of liquid;
- movable arm;
- throughput unit, which includes inlet and outlet pipes of various diameters.
The device is manufactured from materials that are durable, strong and resistant to corrosion.
If the installation will be carried out in a reservoir with clean drinking water, then you should choose a product from those approved for contact with food materials.
In specialized stores, you can purchase a plastic float valve, brass, from of stainless steel as well as bronze.
Floats vary in shape. They can be spherical, cylindrical, or flat. Manufactured from materials such as plastic and stainless steel.
The most common are plastic products. Some manufacturers supply a water level float valve without it, offering to purchase it separately, choosing the option most suitable in size and material.
For example, the float valve is made entirely of plastic. The float of this model is adjustable. There is an external threaded connection.
Among the advantages, one can single out good throughput, small dimensions, allowing it to be mounted in small tanks. The seat is soft-seated to ensure tight closure, even with constant flow pressure variations.
The lever used in the construction is two-knee. Due to this, the closing force of the mechanism increases as the amount of liquid increases. There are models with a parallel float stroke, so they do not have guides.
On some models, the seat and piston are replaceable.
The float valve for the tank has different degrees of opening and closing, which prevents the valve from opening with a slight decrease in water in the tank, the so-called "bell" mode.
Float valves for installation in a tank can be completed with a transition union, which is used to connect a rubber hose to the outlet.
The float valve for the container or tank is supplied complete with rubber seals and a compression nut for attaching to the outside of the tank.
Optionally, there may be a replaceable strainer installed in the inlet. It prevents the passage of contaminants.
The mesh can be coarse or finer. It can be easily removed and washed. Do not use the device without a filter mesh, otherwise large particles may enter the internal mechanism and damage it.
There is such a float stop valve, in which there are two options for installing the float: vertically and horizontally.

Application
Float valves for internal installation in a tank are used:- in open tanks, intended, for example, for irrigation;
- in closed containers, for example, toilet cisterns;
- in filling systems storage tanks water supply systems;
- in industrial and commercial equipment.
- place of installation, that is, the type of tank;
- water temperature;
- filled volume;
- with what capacity the water intake will be carried out.
At high pressure it is rational to use a water level float valve in the tank with a balanced piston device. Then the pressure in the system is balanced and does not prevent the float from rising. If the pressure is weak, then with an incorrectly selected device, filling will be carried out very slowly.
It is also necessary to take into account the pressure in the container. Cylindrical floats are not suitable for closed pressure vessels. Special versions of locking mechanisms are intended for them.
Based on these data, a float valve is selected for a tank of a suitable diameter, size and design.
A plastic float valve is allowed to be used where it will not be exposed to temperatures above 50 ° C.
For steel products, the operating temperature is higher and is equal to 90 ° C. The highest and lowest working pressure is different for different modifications.
For example, the Aquatek float valve has such values of this parameter as 6 bar and 0.6 bar, respectively.
The level float valve is inserted into the wall opening, which must be of the appropriate diameter.
Installation is carried out as follows:
- In the place of the tank where the supply pipe will be located, a hole of the required diameter is made.
- A rubber gasket (included in the kit) is threaded onto the threaded branch pipe, with its help a tight connection is created.
- Then, from the inside of the tank, a fitting is placed into the drilled socket and secured with a crimp nut on the other side. Do not over-tighten it, otherwise you can deform the fitting and spoil the thread.
- Next, the supply pipeline is connected. Suitable fittings are used for this.
- The float valve is set to the water level limit. Adjustment is carried out by screwing or loosening the nut on the movable arm.
- The correct operation of the device is now checked. To do this, the tap installed on the supply pipe opens and the tank starts to fill. Together with the rise in the water level, the float will rush upward. When it reaches the upper adjusted limit, the outlet will close off and the reservoir will stop filling.

Can be used for
One type of device that can be purchased and installed to regulate the level of a liquid in a tank is mechanical float valves for a tank or tank. They perform the function of shut-off and control valves, controlling the flow of water entering the tank. Working in automatic mode, these devices, simple in design, reliably ensure the specified mode of filling the tank with water.
Principle of operation, advantages
When the liquid level drops, the float descends and opens the shut-off valve over the lever arm. If the level has reached a certain value, the floating float closes the valve in the same way, completely shutting off the flow of water at the inlet to the tank. The float is the sensitive element of the automatic device. It usually has a thin-walled, hollow, cylindrical (spherical) structure of brass or stainless steel filled with air.
There are two main designs of float valves, which differ in the device of the lever mechanism: straight and angular. Their principle of operation is the same, the difference lies in the shape of the lever and the location of the valve stem (horizontal, vertical).
