Safety valve 1915 g6/4 6bar 1915.40.159

Safety valve 1915 is a reliable device used to protect pressurized systems – both filled with liquid and inert gas – against exceeding the permissible pressure. It is a key element ensuring the safety of heating, water and industrial installations. Available in a wide range of settings (from 1.5 to 6 bar) and diameters (DN15 to DN50), it allows for precise adaptation to specific needs.

This valve is used in installations with a maximum operating temperature of up to 140°C. The membrane design guarantees tightness and precision, and the ability to vent by turning the cap facilitates servicing. Made of high-quality materials – brass/bronze, spring steel with an anti-corrosion coating and a diaphragm made of a material resistant to aging – ensures long-lasting and trouble-free operation.

Key features and benefits:

• Wide range of applications: ideal for protecting heating, water, gas and industrial installations.
• Precise operation: the diaphragm ensures accurate maintenance of the set opening pressure.
• Durability and reliability: construction from high-quality materials guarantees a long service life.
• Easy servicing: the ability to vent and replace the head facilitates valve maintenance.
• Availability of different pressure settings: allows the valve to be adapted to the specific requirements of the installation (1.5, 2, 2.5, 3, 3.5, 4, 4.5, 5, 5.5, 6 bar).
• Compliance with standards: the valve has a UDT 42-C-04/imp. type examination, which confirms its compliance with applicable safety standards.

The 1915 safety valve is particularly recommended in situations requiring reliable protection against overpressure, e.g. in central heating systems, domestic hot water installations or in industrial processes using liquids or gases under pressure. The possibility of mounting up to three safety valves on one heat exchanger increases flexibility and allows for the protection of installations with a higher thermal power than results from standard selection tables. Remember to mount in a vertical position with the inlet from below for proper device operation.
