Caleffi diaphragm safety valve 1/2 x 3/4 - 6 bar - heating valve 🌡️

Membrane safety valve 1/2" x3/4"

Pressure relief valve heating valve from Caleffi

The diaphragm safety valve 1/2" x3/4" Caleffi's safety valve is a high-quality safety valve specifically designed to reliably protect closed hot water systems from excessive pressure. This valve responds precisely to a set pressure of 6 bar, thus ensuring the safe operation of your heating or hot water system.

Compliant with the requirements of TRD 702, DIN 4753 Part 1, and DIN 1988, this pressure relief valve serves as an essential safety device. The angled design with integrated lifting device simplifies both installation and maintenance of the valve. The robust housing is made of corrosion-resistant brass, while the spring cap is made of durable plastic. Both the sealing disc and the diaphragm are made of a special, hot-water-resistant elastomer (EPDM), guaranteeing high reliability even at temperatures up to 100°C. The design of the diaphragm safety valve ensures consistent sealing, even under sustained loads and changing operating conditions.

Thanks to IG-IG connections, the safety valve 1/2" x3/4" for easy integration into existing piping systems. It is ideally suited for water as the operating medium and meets all common safety requirements for modern heating and hot water systems.
