Full port ball valves

Check valve in the return, can be opened, 200 mm wc, especially for solar systems.In order to prevent unwanted circulation, it is mandatory to mount an additional check valve in the flow on site (see below the item).

Ball valve key-actuated,
easy handling, no risk of scalding

Solar safety group
Solar pressure relief valve 6 bar, pressure gauge resistant to high temperature 0-6 bar with valve, fill and drain valve for flushing and filling, flat sealing connection for an expansion tank

Compact design insulation with optimised function made of durable elastic EPP;
100 % insulated valves and fittings - excellent ventilation and cooling of the pump

Full metal solar thermometer, 0-160 °C
can be pulled off, with immersion sleeve, integrated in the ball valve

Fully assembled with flat gaskets

With solar circulation pump by Grundfos or Wilo
already installed

Pump can be isolated,
so that it can be replaced without draining

Volumetric flowmeter
Flowmeter with adjustable flow limiter and function control device, for temperatures up to 120 °C, measuring range 3-22 l/min

Flush and fill unit integrated
two fill and drain valves (on the flowmeter and on the safety group) permit flushing and filling the system
