The SONDA ball valve is used in central heating systems where it is necessary to have a temperature/pressure point. The valve is usually installed at the inlet and outlet of the system in order to determine the temperature difference (when connected to a heatmeter).
Threaded end connections:
• female according to UNI ISO 228/1.
Red aluminium T-handle.
All the valves comply with the regulation 2014/68/CE and are tested 100% on pneumatic seal with electronic control.
• The SONDA valve has a boss on the underside of the valve (threaded M10x1).
By removing the cap, it is possible to insert a temperature measuring probe.
The unique design of the drilled ball awolis the probe to be fully inserted into the fluid flow.
