Drosselventil til genfyldning af en vandbrönd

摘要

A water well recharge throttle valve (1) is configured as a hydraulic actuated flow control device (5) that permits calibrated throttling of water used in Artificial Storage and Recovery (ASR), Salt Water Barrier, Dedicated Recharge and Injection Wells to prevent the free cascading of water and thereby eliminating the entrainment of air which may cause air fouling, bio-fouling, calcite formation with a resultant reduction in permeability of the aquifer.
