Safety valve 1915 6.0 bar, 1 inch 1915.25.159

Safety valve – reliable installation protection

The 1915 safety valve is a key element protecting pressure systems from exceeding permissible values. Designed to work with inert liquids and gases, it provides effective protection in a wide range of applications. Its membrane design guarantees precise operation and long-term reliability.

This valve is used in heating systems, water installations, and industrial processes requiring pressure control. Thanks to a wide range of available settings (from 1.5 to 6 bar), it can be adapted to the specific needs of each installation. The model with a 1-inch thread and a 6.0 bar setting (catalog number 1915.25.159) is particularly popular due to its versatility and efficiency.

Features and benefits

• Wide range of applications: ideal for protecting systems with inert liquids and gases.
• Precise adjustment: many pressure settings are available (1.5, 2, 2.5, 3, 3.5, 4, 4.5, 5, 5.5, 6 bar), allowing for accurate adaptation to installation requirements.
• High working temperature: the maximum medium temperature is 140°C, allowing the valve to be used in harsh conditions.
• Glycol compatibility: the valve can operate with a medium containing up to 50% glycol.
• Solid construction: ensures long-lasting and trouble-free operation of the device.
• Easy installation: standard thread facilitates integration with the existing installation.

Available thread sizes and setting ranges for the 1915 series safety valves make it easy to select the appropriate model for a specific application: G ½”, G ¾”, G 1”, G 1 ¼”, G 1 ½”, G 2” with settings from 1.5 to 6 bar.

Design and application

The 1915 series safety valves use a membrane to precisely control the pressure in the system. Their design ensures a quick response to pressure increases above the set setting value and effectively relieves the installation of excess medium – minimizing the risk of damage and failure of equipment connected to the system. A wide selection of thread sizes (from G ½” to G2”) allows the valve to be adapted to different pipe and conduit diameters in the installation – both in residential buildings and industrial facilities. These valves are particularly useful where high reliability and precision of the overpressure protection system are required.
