Safety valve 4.0 bar 1915 3/4 inch 1915.20.152

Safety valve – protection of the installation and peace of mind

The 1915 safety valve is a reliable device designed to protect pressure systems filled with liquid or inert gas from exceeding the permissible pressure. The membrane design provides effective protection, and a wide range of available settings (from 1.5 to 6 bar) allows you to choose the right model for the specific needs of the installation. This particular model, with catalog number 1915.20.152, has a setting of 4 bar and is intended for installations with a 3/4 inch thread.

Construction and application

The 1915 series safety valves are used in water, heating and other installations with non-adhesive liquids with a working temperature of up to 140°C. They are particularly useful where there is a risk of pressure increase, e.g. in closed heating systems with a boiler. Thanks to the possibility of mounting up to three safety valves on one heat exchanger, installations with a higher thermal power than would result from standard selection tables can be protected. The construction of brass or bronze guarantees durability and corrosion resistance.

Key features and benefits

• Wide range of settings: Available versions from 1.5 to 6 bar allow precise adjustment to the requirements of a specific installation.
• Versatility: Can be used with various types of liquids and inert gases.
• Durability: Made of high-quality materials (brass/bronze, spring steel) ensures a long service life of the device.
• Easy servicing: Valves with a diameter of 1/2" and 3/4" can be repaired by replacing the head (1916).
• Compliance with standards: They have a UDT 42-C-04/imp. type examination, mark 0085, which confirms their safety and reliability.
• Possibility of venting: The valve design allows easy venting by turning the cap.
• Flow coefficient: Selection of the valve depending on the thermal power of the installation is possible thanks to tables providing flow coefficients for steam and gases as well as liquids (see table in the catalog card).

The 1915 safety valve is an investment in the safety and trouble-free operation of a heating system or other pressure system. Its solid construction and the ability to precisely adjust parameters make it an ideal choice for both professional installers and end users.
