Hydrolux safety relief valve DN25 bronze, female thread 5501-04.000

Hydrolux overpressure relief valve is a reliable protection for central heating and domestic hot water systems against excessive pressure. Made of lead-free bronze, it is characterized by durability and corrosion resistance, guaranteeing a long service life even in harsh operating conditions. Designed for use in systems with a maximum working pressure of PN 10.

This valve, equipped with a tapered internal gas thread (BSPT) with a diameter of 1 inch (25 mm), ensures a tight and secure connection to the installation. Its pressure adjustment range, from 5 to 50 kPa, allows for precise adjustment to the specific needs of a given system. The absence of an impulse tube simplifies installation and maintenance.

Design and application

The Hydrolux valve is used in closed heating installations where there is a risk of pressure increase due to thermal expansion of the water or failure of other system components. Its task is to automatically release excess pressure, protecting pipes, radiators and other components from damage. This ensures that the installation operates safely and efficiently for a long time. The construction of lead-free bronze (90/10) ensures resistance to aggressive media and corrosion, which is particularly important in systems with water of varying degrees of hardness.

Advantages and benefits

• Installation protection: Effectively protects the system from the effects of excessive pressure - pipe bursts, radiator damage or boiler failures.
• Durability: Made of high-quality lead-free bronze, guaranteeing a long service life and corrosion resistance.
• Precise adjustment: The adjustment range of 5-50 kPa allows for accurate adjustment of the valve to the parameters of a specific installation.
• Easy installation: BSPT internal thread facilitates quick and tight connection to the existing installation.
• Maintenance-free: The valve operates automatically, requiring no regular maintenance or user intervention.
• Compliance with standards: The product meets appropriate safety and quality standards, ensuring reliable operation.

The Hydrolux valve is an investment in the safety and reliability of the heating system - both for professional installers and end users. Its solid construction and precise operation translate into peace of mind and minimizing the risk of failure.
