Hydraulic safety group for DHW tanks with shut-off valve and check valve with supervision option 1/2" 526142

Safety and control in your hot water system

A safety group is a key element of every DHW installation, providing protection for the tank and the entire system against the effects of excessive pressure or failure. This model combines several functions, offering comprehensive protection and ease of use. It includes an shut-off valve, which allows easy isolation of the tank in case of service or maintenance, and a check valve with monitoring, which prevents backflow of water and allows flow control.

Construction and materials

Made of durable brass with a chrome finish, the safety group is characterized by high corrosion resistance and long life. A stainless steel socket further increases the durability and hygiene of the device. Solid materials guarantee reliable operation even in difficult operating conditions.

• Brass body provides resistance to high temperatures and pressures.
• Chrome finish enhances aesthetics and protects against corrosion.
• Stainless steel socket ensures hygiene and connection durability.

Operating parameters and application

The safety group is designed to operate in installations with a maximum pressure of 10 bar and a temperature of 120°C. Set to 7 bar at the factory, it provides effective protection against exceeding the permissible pressure values in the tank. The rated power for the 1/2" version is 4 kW, making it suitable for most standard DHW tanks. It meets the requirements of EN 1487 standard, confirming its safety and quality.
