Safety valve 1915 g6/4 5bar 1915.40.153

Safety valves of the 1915 series are reliable devices designed to protect pressurized systems filled with liquid or inert gas from exceeding the permissible pressure. They are widely used in heating, water and industrial installations where precise and effective overpressure protection is required. Available in various sizes (DN15 to DN50) and pressure settings (from 1.5 to 6 bar), they allow adaptation to specific installation needs.

The 1915 safety valve with catalog number 1915.40.153 is a model with a G 1 1/2" connection and a setting of 5 bar. It is a proven component that can be used both in new installations and in the modernization of existing systems. The valve design allows mounting up to 3 units on one heat exchanger, which allows protecting installations with a higher thermal power than would result from standard calculations.

Key features and benefits:

• Wide range of applications: The ability to use with various media – steam, gases, liquids – and at temperatures up to 140°C makes it a universal solution for many industries.
• Precise pressure regulation: Availability of many pressure settings (1.5, 2, 2.5, 3, 3.5, 4, 4.5, 5, 5.5, 6 bar) allows for accurate adaptation to the requirements of a specific installation.
• Durable construction: Made of brass/bronze and internal components of spring steel ensures long-lasting and reliable operation even in difficult operating conditions.
• Serviceability: Valves with a diameter of 1/2" and 3/4" can be repaired by replacing the replaceable head (model 1916), which reduces operating costs and extends the life of the device.
• Compliance with standards: The valves have a UDT type examination (42-C-04/imp.) with mark 0085, which confirms their safety and compliance with applicable regulations.

This valve is particularly recommended where overpressure protection is required in heating and water installations with non-adhesive liquids. Thanks to its design and adjustment possibilities, it is an optimal solution for both professional installers and end-users looking for reliable protection of their systems. Remember to mount in a vertical position with the inlet from the bottom for proper valve operation. The maximum glycol content in the medium should not exceed 50%.
