Sonda
Application fields:
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.
Operation devices:
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.
Bore:
full (3/4" x 1”) reduced (1”x 1”).
Stem:
anti blow out.
Seats:
high resistance virgin PTFE.
Upper seal:
3 seals
1 PTFE ring - high pressure.
2 O-Ring - low pressure.
Finishing:
Internal surfaces are nickel free and comply with forthcoming European drinking water regulations.
Ball:
special self-washing system that avoids stagnation.
Temperature limits:
for fluids from –15°C to +110°C
Pressure limits:
for fluids of 40 bar (20°C)
