Safety valve 1915 g 5/4 inch 2.5bar 350kW 1915.32.150

Safety valves of the 1915 series are devices designed to protect pressure systems, both those filled with liquid and inert gas. Their membrane-based construction guarantees reliable operation and precise response to pressure increases. Model 1915.32.150, with a diameter of 5/4 inch and a setting of 2.5 bar, is particularly effective in systems with a power of up to 350 kW.

This valve finds application in a wide range of heating installations, domestic hot water systems, and in industry, wherever protection against excessive pressure is necessary. Thanks to the possibility of selecting the setting (from 1.5 to 6 bar), the valve can be adapted to the specific requirements of a given installation. The maximum permissible medium temperature is 140°C, making it a universal solution for many applications.

• Wide application: ideal for protecting installations with liquid or inert gas.
• Precision of operation: the membrane ensures a quick and accurate response to pressure increases.
• Versatility: the ability to select the setting in the range of 1.5 to 6 bar allows adaptation to different systems.
• Durability: maximum operating temperature up to 140°C ensures reliability in harsh conditions.
• Efficiency: the model with a setting of 2.5 bar and a power of 350 kW effectively protects high-power installations.
• Easy installation: standard 5/4 inch thread facilitates integration with existing installations.

The 1915 safety valve also has favorable flow parameters for steam and gases (alpha coefficient = 0.51) and for liquids (alpha_c coefficient = 0.35 for b1=10% and 0.42 for b1=25%). It should be remembered that the maximum glycol content in the medium should not exceed 50% to ensure proper valve operation. CAD and PDF drawings are available to facilitate system design and installation – it is worth using them during installation planning. This valve does not require a UDT declaration upon acceptance, simplifying the process of verifying compliance with safety standards.
