Precautions for Rexroth pressure reducing valves

Create Date: 2024-8-30 12:03:23|Source: Rexroth/Rexroth

1. For easy operation and maintenance, the valve is generally installed upright on the horizontal pipeline.

2. The installation of the pressure reducing valve must be in strict accordance with the direction of the arrow on the valve body and keep it consistent with the direction of fluid flow. If the water quality is not clean and contains some impurities, a filter must be installed at the upstream inlet of the pressure reducing valve.

3. In order to prevent overpressure behind the valve, a pressure reducing valve should be installed at a distance of not less than 4M from the valve outlet.

4. The pressure reducing valve plays a certain role in the pipeline, in order to prevent the harm of water hammer, a small expansion tank can also be installed to prevent damage to the pipeline and valve, the filter must be installed in front of the inlet pipe of the pressure reducing valve, and the expansion tank must be installed behind the outlet pipe of the pressure reducing valve!

5. If you need to install a pressure reducing valve in a hot water system, you must install a check valve between the pressure reducing valve and the expansion tank. This not only allows the expansion tank to absorb the increased volume of water due to thermal expansion, but also prevents the influence of hot water backflow or pressure fluctuations on the pressure reducing valve, ensuring that the pressure reducing valve works normally for a long time.
