Safety valve 1915 g 5/4 inch 3bar 350kW 1915.32.151

Safety valve – protection for heating systems and pressure systems

The 1915 safety valve is a reliable device designed to protect pressure systems filled with liquid or inert gas from exceeding the permissible pressure. A wide range of available settings (from 1.5 to 6 bar) allows for precise adjustment to the specific needs of the installation. This is a key element ensuring safe and efficient system operation, protecting it from potential damage caused by excessive pressure.

Construction and application

These valves are used in heating, water installations, and systems using other non-adhesive liquids with an operating temperature of up to 140°C. The valve design allows mounting up to three units on one heat exchanger, allowing protection of installations with a higher thermal power than would result from a single valve. This allows for effective removal of all thermal power of the installation in the form of saturated steam. The valve is made of high-quality materials – a brass or bronze housing, and internal elements made of spring steel coated with a galvanic coating for corrosion protection. The diaphragm and seal are made of a material resistant to high temperature and aging.

Key features and benefits

• Wide range of settings: Available settings from 1.5 to 6 bar allow for precise adjustment to the specifics of the installation.
• Universal application: Can be used with various media – steam, gases and non-adhesive liquids.
• High operating temperature: Maximum operating temperature up to 140°C ensures reliable operation in difficult conditions.
• Repairable: Valves with a diameter of 1/2" and 3/4" can be repaired by replacing the replaceable head (1916).
• Easy installation and maintenance: The valve design allows venting and cleaning the seal and seat without the need to disassemble the entire device.
• Compliance with standards: It has a UDT 42-C-04/imp. type examination, mark 0085, which confirms its safety and reliability.

The 1915 safety valve is an investment in the safety and long-term efficiency of a heating system or other pressure system. Its solid construction and precise operation guarantee protection against the effects of exceeding the permissible pressure, minimizing the risk of failure and costly repairs. Selecting the appropriate valve size depending on the thermal power of the installation is crucial to ensure optimal protection – detailed information can be found in the product catalog card.
