Safety valve 1915 g 3/4 inch 2.5bar 100kW 1915.20.150

Safety valve – protection for your heating system

The 1915 safety valve is a reliable device designed to protect pressurized systems – both those filled with liquid and inert gas – against exceeding the permissible pressure. It is a key element ensuring the safe and efficient operation of heating, cooling or other installations where pressure control is a priority. The membrane design guarantees precise operation and long service life.

Construction and application

The 1915 safety valve finds wide application in central heating installations, solar systems, and industrial equipment. Its main task is to automatically relieve overpressure, which can occur as a result of the expansion of liquids or gases under the influence of temperature, failure of the circulation pump or other unforeseen situations. This protects the installation components from damage and ensures the safety of users. The 3/4 inch model with a 2.5 bar setting is particularly suitable for installations with a power of up to 100kW.

Worth knowing: Safety valves of the 1915 series are available in various sizes (DN15-DN50) and with different pressure settings (from 1.5 to 6 bar), allowing them to be adapted to the specific needs of each installation. The maximum operating temperature of the valve is 140°C, which makes it a universal solution for most standard heating systems. It can be used with media such as steam, gases and liquids, but it is important to remember to limit the glycol content to a maximum of 50%.
