Safety valve 1915 6.0 bar, 3/4 inch 1915.20.159

Safety valve 1915 is a reliable device designed to protect pressurized systems – both filled with liquid and inert gas – against exceeding the permissible pressure. It finds application in heating, water installations and many others, where pressure control is crucial for safety and proper operation. Available in a wide range of sizes (DN15 to DN50) and pressure settings (from 1.5 to 6 bar), allowing for precise adaptation to specific installation needs.

This valve is characterized by its versatility – it can operate with steam, gases and liquids at temperatures up to 140°C. The valve design allows mounting of up to three units on one heat exchanger, increasing its capabilities for installations with higher thermal power. Additionally, valves with a diameter of 1/2" and 3/4" can be easily repaired by replacing the head (1916).

Key features and benefits:

• Wide range of applications: ideal for securing heating, water, gas and other pressure systems.
• Precise adjustment: availability of different pressure settings (1.5, 2, 2.5, 3, 3.5, 4, 4.5, 5, 5.5, 6 bar) ensures optimal adaptation to installation requirements.
• High operating temperature: possibility of use in systems with a temperature of up to 140°C expands its scope of use.
• Easy servicing: possibility of head replacement in 1/2" and 3/4" models reduces repair costs and downtime.
• Compliance with standards: the valve has a UDT 42-C-04/imp. type examination, confirming its safety and reliability.
• Solid construction: made of high-quality materials (body brass/bronze, internal parts Ms 58) guarantees long-lasting and trouble-free operation.

The 1915 safety valve is particularly recommended for installers due to its ease of installation (vertical installation with bottom inlet) and serviceability. For end users, this means above all peace of mind – confidence that their installation is protected against the effects of excessive pressure. It should be remembered to limit the glycol content in the medium to a maximum of 50%. The selection of the appropriate valve size should be made on the basis of the thermal power of the installation according to the tables available in the technical documentation.
