Safety valve for domestic hot water installation PRESCOR B, GW 1 inch connection, 6 bar 29005

Safety valve for domestic hot water systems

This safety valve from Flamco (AALBERTS HFC), model Prescor B, is a reliable safeguard for your domestic hot water system. Designed to protect water heaters and the entire system from excessive pressure, it provides peace of mind and long-lasting performance. Made of dezincification resistant brass (DZR), it guarantees durability and corrosion resistance.

Construction and application

The Prescor B valve has an internal threaded (female thread) connection (GZ) with a diameter of 1 inch and 1 1/4 inch, making it easy to install in standard installations. The angular design (90°) allows for flexible adaptation to existing space. The diaphragm mechanism ensures precise response to pressure increases, and the opening pressure setting is 6 bar – an ideal value for most domestic hot water systems. The EPDM rubber seal ensures tightness and resistance to high temperatures (up to 95°C).

This valve is designed for continuous operation and works perfectly in potable water systems. Its solid construction and high-quality materials guarantee reliability for years to come. The discharge diameter is 42.4 mm, ensuring effective removal of excess pressure in case of exceeding it.
