Return valve RLV-S 20 angled for side and bottom-fed radiators 003L0125

Return valve RLV-S 20 is a reliable solution for heating systems, designed for radiators supplied from the side or from below. The angular design facilitates installation in tight spaces, and the 3/4 inch internal thread ensures compatibility with most installations. This valve, catalog number 003L0125, is manufactured by the renowned company Danfoss and is characterized by high quality workmanship and durability.

The RLV-S valve serves as an isolating function, allowing individual radiators to be isolated during servicing or repair without having to shut down the entire system. This makes it possible to carry out maintenance work in a convenient and safe manner. Importantly, the valve has a reverse flow function, meaning it blocks the flow of medium in one direction and allows it in the other – this is crucial for the correct operation of the heating installation. The adjustment option allows for precise adjustment of the heat flow to the user's needs.

Key features and benefits:

• Versatility: Designed for radiators supplied from the side and from below – one valve fits different installation configurations.
• Durability: Made of nickel-plated brass, which ensures corrosion resistance and long-term use. Nickel plating is not only protection against rust, but also an aesthetic appearance.
• Precision: A Kv value range of 0.2…1.8 and a Kvs value of 2.2 allow for accurate adjustment of the heat flow in the heating circuit. This translates into thermal comfort and energy savings.
• Easy installation: The angular design (90°) facilitates installation even in hard-to-reach places. A 3/4 inch internal thread ensures quick and tight connection with pipes and radiators.
• Safety: The valve effectively cuts off the flow of heat transfer medium, allowing safe maintenance work without having to drain the entire system.
• Adjustment: The ability to set/adjust allows for optimization of the heating installation and adaptation to individual user needs.

The RLV-S 20 valve is a solid and reliable element of every heating system, which will ensure comfortable use for many years. Its compact dimensions (height 35 mm) allow for discreet installation, and high quality workmanship guarantees trouble-free operation for many heating seasons.
