Temper balancing ball valves are designed for regulation (balancing) of the working fluid flow in heating, cold supply and ventilation systems. The ball has a special orifice and the valve is equipped with a scale of values. Regulation is carried out by turning the handle with the pointer. The selected position of the handle is fixed with a bolt and a nut-butterfly.

Two types of regulating ball valves:

1)With measuring nipples (see the picture and the drawing on the page). All the measurements could be

measured by a flow meter.

 

2) Without measuring nipples. Flow adjustment is made only by a handle with index.
