Check valve RLV 15 straight with drain and radiator filling option 003L0144

Return valve – reliable regulation in your heating system

The RLV 15 return valve is a key component of central heating installations, allowing precise shut-off of individual radiators. This allows servicing and repairs to be carried out without having to shut down the entire system. This solution is appreciated by both professional installers and end users who value comfort and independence in managing the temperature in their homes.

This valve is distinguished by its simple construction and ease of installation, while offering high functionality. The additional function of draining and filling the radiator significantly facilitates maintenance and preparation of the installation for the heating season. Made of high-quality brass with a nickel-plated surface, it ensures durability and corrosion resistance.

Functionality and construction for demanding users

The RLV 15 valve is designed for versatility. It fits both side- and bottom-fed radiators, and its 1/2 inch internal thread ensures compatibility with most standard installations. A Kvs value of 2.5 and a Kv range of 0.2 to 2.3 guarantee optimal flow of the heating medium, and the reverse flow direction ensures correct valve operation in the system.

The valve's construction allows for adjustment and setting, giving you full control over the heating process. Nickel plating of the surface protects against corrosion and external factors, ensuring long-term reliability even in difficult working conditions (maximum medium temperature is 120°C). The valve meets the PN10 standard, confirming its safety and compliance with applicable standards.

• Individual regulation: Ability to shut off a single radiator without affecting the rest of the installation – ideal for servicing or replacing a radiator.
