Hydraulic safety group for DHW tanks for horizontal installation, with shut-off valve and check valve with supervision option 3/4" 526152

Safety and comfort of using hot water

The safety group for hot water tanks is a key element of every installation, providing protection against excessive pressure and temperature. This model, designed for installation in horizontal systems, combines several functions in one compact unit – shut-off valve, check valve with monitoring capability, and pressure relief mechanism. This solution is appreciated by installers for its ease of installation and diagnostics, and by end-users for increased safety and system reliability.

Functionality and construction

The group's construction is based on high-quality brass, which guarantees durability and corrosion resistance. The chrome finish not only improves aesthetics but also increases resistance to external factors. The G 3/4" connections (inlet – male thread, outlet – female thread) comply with ISO 228-1 standard, which facilitates integration with existing installations. The check valve with monitoring function allows for visual control of correct water flow, and the shut-off valve allows for easy isolation of the tank in case of service or maintenance.

• Overpressure protection: Factory setting at 7 bar provides effective protection against exceeding the permissible pressure in the installation.
• Backflow protection: The check valve prevents water from flowing back from the tank into the water supply network.
• Monitoring capability: The monitoring function of the check valve facilitates the diagnosis of potential water flow problems.
• Wide temperature range: Operation in the range of 2°C to 120°C allows the safety group to be used in various operating conditions.
• Maximum relief capacity: Up to 10 kW - ensures effective pressure reduction in case of its increase.
• Compliance with standards: EN 1487 certification confirms compliance with European safety and quality standards.

The group is characterized by a maximum operating pressure of 10 bar and a medium temperature range of 2°C to 120°C. The factory setting for the relief pressure is 7 bar, and the maximum relief capacity is 10 kW. Made of brass and chrome-finished, it has inlet connections G 3/4" A (ISO 228-1) male thread and outlet connections G 3/4" (ISO 228-1) female thread.

The safety group should be installed by a qualified installer in accordance with applicable regulations and manufacturer's recommendations. A properly installed safety group guarantees safe and comfortable use of hot water for years to come.
