Hydraulic safety group for DHW tanks with shut-off valve and check valve with monitoring capability 3/4" 526151

Hydraulic safety group for DHW tanks – comprehensive installation protection

The safety group is a key element of every DHW installation, providing protection against excessive pressure and temperature. This model, equipped with an shut-off and check valve with supervision option, is designed for mounting on domestic hot water tanks with a 3/4 inch connection. The brass construction guarantees durability and corrosion resistance, and the chrome finish enhances the aesthetics of the installation.

Functionality and application

The group performs a protective function, protecting the tank and the entire installation from the effects of increased water pressure or temperature. The shut-off valve allows easy isolation of the group for servicing or replacement, and the check valve prevents backflow of water, which is particularly important in installations with instantaneous water heaters or other devices sensitive to pressure changes. The supervision option allows for visual monitoring of the valve status.

Parameters and characteristic features

• Made of brass – ensures corrosion resistance and long life.
• Chrome finish – improves aesthetics and facilitates cleaning.
• Maximum working pressure: 10 bar – safe operation under standard installation conditions.
• Maximum working temperature: 120 °C – possibility of use in installations with elevated temperature.
• Factory setting: 7 bar – optimal setting for most home installations.
• Rated power: 10 kW for 3/4 inch connection – matched to typical DHW tanks.
• Complies with EN 1487 standard – confirmation of product safety and quality.

Installation and operation

The safety group is intended for horizontal mounting, which should be taken into account during installation planning. The shut-off valve facilitates servicing without the need to disassemble the entire group, and the check valve ensures proper water flow and prevents damage to other installation components. Regular inspection of the valve condition (thanks to the supervision option) allows for quick detection of any problems and prevention of failures.
