Pressure regulation in a water-line network

The valve (series 90) reduces high pressure to a fixed lower pressure value regardless of flow and pressure changes before the valve. Using the valve allows:

• reducing the number of water-line network breakdowns and the related costs,
• reducing water losses,
• adjusting water-line network operating parameters depending on the changing operating conditions,
• automatization of the water distribution process.

2. Flow rate regulation.

The valve (series 40) regulates the flow rate in the pipeline, maintaining fixed flow on the water outlet regardless of pressure or flow changes under the valve. Using the valve allows: 

• regulating flow capacity from the main pipeline to the specified distribution zone, field reservoir, etc.
• regulating pump flow capacity (in a deep well).

3. Pressure regulation.

The valve (series 50) maintains pressure inside pre-valve the zone on a minimal, fixed level. Works in a modal way, i.e. opens when the pressure on the valve inlet increases and closes gradually (not causing surges)when the pressure drops.
Using the valve allows:

• maintains min. fixed network pressure (e.g. in a higher distribution system)
• prevents surges during abrupt pump stoppage.

4. Water level in tanks regulation.

The valve (series 100) controls the water level inside the tank using a float. The valve opens up completely, when the surface of the water reaches a pre-determined min. level and allows filling the tank to the max., after which the valve closes shut.
Using the valve allows:

• eliminating tank overflows,
• reducing pumping costs.

5. Valve maintaining constant water level.

The valve (series 210) controls the max. amount of water in the tank, without using a float, which remains completely opened until reaching a pre-defined max. level, when he closes shut to prevent the tank from overflowing.
Using the series 210 open/close valve
allows:

• preventing the tank from overflowing.

 6. Valve maintaining constant water level in the tank.

The valve (series 208) controls the water level in the tank, maintaining a constant pre-defined level, regardless of flow or pressure changes on the tank's entry. The valve works in a modal way, without a float, on the basis of the hydrostatic pressure values.

Using the valve allows:

• eliminating tank overflows,
• reducing the effect of surge,
• minimizing sudden velocity changes inside the pipelines.

7. Valve preventing excessive flow.

The valve (series 85) during normal operation remains completely open and closes when an uncontrolled pipeline leak during a breakdown occurs. These type of valves are installed on main pipelines and protect them from possible damage due to large amounts of water flowing out:

• during highway, road, railway, etc. washouts
• everywhere a pipeline passes next to an important building subject to damage
• due to pipeline crack.

8. Pump control valve.

The valve (series 60) is installed on the pumps delivery pipeline to protect it against surges during pump startup and stoppage. Very often, additional anti-surge valves (series 52) are used and installed on the delivery pipeline outlet, whichprotect the pipeline system from surge during electrical power failure, dumping excess water into the atmosphere of the tank.
Using this type of valves allows: avoiding possible costs related to pipeline, pump, etc. damages that happened during a surge.

9. Valve maintaining constant water level in the tank.

The valve (series 400) controls the water level in the tank, maintaining a constant pre-defined level, regardless of flow or pressure changes on the tank's entry.
The valve works in a modal way and is controlled by a float. These types of valves are used with open filters for maintaining constant filtration speed. Using the valve allows:

• eliminating tank overflows,
• reducing the effect of surge,
• zminimalizowanie gwałtownych zmian prędkości w rurociągach
