Safety valve 1915 g 1 inch 3bar 200kW 1915.25.151

Safety valve – protection for your system

The 1915 series safety valve is a reliable device designed to protect pressurized systems filled with liquid or gas. Its main function is to protect against exceeding the permissible pressure, which ensures safe and efficient operation of the entire system. The valve design allows it to be used in various applications, both in domestic and industrial installations.

This valve, with a 1-inch connection diameter and a setting of 3 bar, is perfect for systems with a power of up to 200 kW. Made of high-quality materials, it guarantees long-lasting and trouble-free operation. This is particularly important for installers who value the solidity and durability of components.

Construction and application

The 1915 safety valves are characterized by a diaphragm design, which ensures precise operation and a quick response to pressure increases. A wide range of available settings (from 1.5 to 6 bar) allows the valve to be adapted to the specific requirements of a given installation. The maximum operating temperature is 140°C, which expands its range of applications.

• Medium: the valve is compatible with steam, gases and inert liquids.
• Construction: the housing is made of brass or bronze, the cover of Gd-Zn or brass/bronze, and the internal elements of Ms 58 steel provide resistance to corrosion and mechanical damage.
• Diaphragm: made of a material resistant to high temperature and aging, which guarantees long-term tightness and reliability.
• Flow coefficient: for steam and gases it is 0.67, and for liquids b1 = 10% (alpha_c) – 0.40 and b1 = 25% (alpha_c) – 0.52. These parameters are crucial when selecting the appropriate valve for a specific application.

Thanks to the possibility of venting by turning the cap and the ease of cleaning the seal and valve seat (by unscrewing the upper insert), this valve is easy to maintain and service – which will be appreciated by both installers and end users.

Key advantages

• Versatility: can be used with various media (steam, gases, liquids).
• Precision: diaphragm design ensures accurate operation.
• Durability: high-quality materials guarantee long-term operation.
• Easy maintenance: the ability to vent and clean internal elements facilitates servicing.
• Wide range of settings: adaptation to different installation requirements (from 1.5 to 6 bar).
• Compliance with standards: the valve has a UDT 42-C-04/imp type test confirming its safety and quality.
