ALV charging valve, insert rotatable from the outside, DN25 IG, 72°C

• Mixing valve for return temperature boosting with internal threaded connections. This self-acting charging valve is installed in boilers with or without a buffer storage tank and operates without external power. It serves to maintain a high return temperature. The optimal boiler return temperature prevents condensation and boiler creosote buildup, resulting in less environmental impact and an extended boiler lifespan. These charging valves can also improve stratification in buffer storage tank systems.

• The thermocouple can be rotated in its direction of action under pressure and without tools.

Technical data:

• Maximum operating temperature: 120°C
• Maximum operating pressure: 10 bar
