How does it work?
As the pressure increases, the cross-section of an orifice decreases proportionally. The flow of liquid thus remains constant.

What kind of valve is it?
As the name suggests, this is a valve which automatically regulates the flow within a system. Regardless of pressure fluctuations, the valve keeps the flow permanently constant. Since this state can be maintained within a wide range of pressures, this valve is particularly suitable for networks suppling several users. This is why it is also described as a “balance valve”. The valve has no manually operated parts and requires no maintenance once it has been installed. There are no electrical or pneumatic control lines. The valve is selfactuating and requires no additional energy source to operate.
