Heating circuit set Easyflow DN25 (1") control circuit with constant value, thermal 35-60 °C, pump Grundfos UPM3S AUTO 25-60

• For temperature control with surface heating systems that are operated with a constant flow temperature
• Can be set from 20°C to 45°C

Flow:
1 x flow pump flange ball valve with thermometer handwheel (thermometer ring, red, 0-120°C)
1 x screw connection
1 x 3-way thermostatic mixing valve
1 x pump

Return:
1 x return pump flange ball valve with thermometer handwheel (thermometer ring, blue, 0-120°C)
1 x screw connection
1 x adjustable check valve by turning the handwheel to 45 °C
1 x T-piece for mixer

Advantages:
• Excellent venting
• The check valve does not get jammed due to low thermal load (check valve in the return ball valve)
• Check valve adjustable without tools
• Interchangeable spindle seals for the ball valves
• No rusting/seizing of screw connections due to union nuts made of brass
