Check valve RLV-S 15 straight for individual radiator shut-off during operation or renovation 003L0124

Radiator return valve – reliable regulation and user comfort

The RLV-S 15 return valve is a simple yet effective solution for individually shutting off radiators in central heating systems. It is suitable for both operation and renovation work, allowing for precise control of the temperature in individual rooms. It is a key element for optimizing the operation of the heating system and reducing operating costs.

This valve is designed for use in radiators supplied from the side or from below. Its solid construction of nickel-plated brass guarantees long-lasting and trouble-free operation, even in difficult conditions. Nickel plating provides corrosion resistance and an aesthetic appearance.

Functionality and application

RLV-S 15 allows you to easily cut off the supply of hot water to a specific radiator without having to shut down the entire system. This is an ideal solution during repairs, radiator replacement or temperature regulation in individual zones of the building. The ability to set/adjust allows you to adapt the flow of the heating medium to individual needs. The reversed flow direction ensures correct valve operation in standard installations.

• Individual regulation: Precise temperature control in each room.
• Easy installation: Standard 1/2 inch thread facilitates integration with the existing installation.
• Durability: Made of high-quality nickel-plated brass, resistant to corrosion and mechanical damage.
• Versatility: Compatible with radiators supplied from the side and from below.
• Safety: Provides effective cut-off of heat supply if necessary, minimizing the risk of failure or leaks.

The RLV-S 15 valve is characterized by appropriate flow parameters – the Kv value range is from 0.2 to 1.8, and the Kvs value is 2.2, which ensures optimal temperature regulation while maintaining an efficient flow of the heating medium. Its compact dimensions (height 30 mm) allow for discreet installation even in tight spaces. The lack of a drain function eliminates the risk of accidental emptying of the installation during servicing or maintenance of the valve.
