ARI-PREDU® pressure reducer
available in the Hagelschuer online shop
Our Partner for fittings, the company AARI-Armaturen Albert Richter GmbH & Co. KG, we have already presented in detail in our column “Hagelschuer and its partners”. Today we would like to go into more detail about the ARI-PREDU® pressure reducing valves. Pressure reducers are special valves, whose task and function therein, automatically and without auxiliary power to ensure that the pressure in the downstream pipelines never rises above the preset value. Basically, a distinction is made between the upstream pressure that prevails in the pipeline system upstream of the valve and the downstream pressure that prevails in the pipeline system downstream of the valve. With the help of a diaphragm that reacts to the downstream pressure, the valve opens and closes to allow either more or less steam to flow through. The pressure reducers from ARI impress with their compact design. The exact set point can be achieved simply by adjusting the spring plate, which then changes the preload of the spring. Hagelschuer offers all nominal sizes as well as various pressure ranges in its online store.
