Brass ball valves are the best shut-off device for geothermal systems because:
- does not deteriorate from dirt (grains of sand) like plastic taps;
- do not create significant hydraulic resistance as valved taps.
The solution for the correct connection to equipment (heat pumps, storage tanks, circulation pumps, etc.), plumbing fittings (valves, gauges, pressure gauges, expansion tanks, etc.) and other components that need to be disconnected from the system for replacement or maintenance. The use of fixed elements that do not allow for detachment results in the need to cut pipes for the simplest of service operations.
