Lance valve for efficient drinking water circulation in long water pipes

LK 551 lance valve for drinking water circulation

Product overview

The LK 551 lance valve was specially developed for efficient drinking water circulation. It ensures that the water temperature in the pipe system remains constant and minimizes the waiting time for hot water at the tap.

How it works

By installing it in the circulation line, hot water is continuously returned to the point of use. This prevents cooling in the pipes and ensures instant hot water supply at all times.

The robust design made of high-quality materials guarantees long-term pressure and temperature resistance, even under the high demands of building operation.

Advantages at a glance

Installing the lance valve optimizes comfort in properties with long pipes, such as apartment buildings or large office buildings. You save time and water, as cold water doesn't run down the drain unused.

The consistent temperature throughout the system also protects pumps and fittings by minimizing temperature fluctuations. This contributes to a longer service life of the entire drinking water installation.

Installation and operation

It is installed directly in the circulation line before the return to the hot water tank. Thanks to its compact design and standardized connection dimensions, the lance valve can be easily integrated into existing systems.

Regular maintenance is not costly and can be carried out as part of the annual inspection of the drinking water system.

Important NOTE

The mixing valve is not included. If you are interested, you can find the matching LK 511 HydroKit HWC in our online shop.
