Pre-Set Flow Controller – Overview The Pre-Set flow control valves provide a constant flow rate independent of line pressure changes. It is suitable for pure liquid applications. Operation is by means of a rubber orifice that reduces in size as the pressure increases, thus balancing the flow. Installation is possible on any plane to fit existing pipework. Available either screwed or as a wafer to fit between flanges. All materials are WRC-approved for use in drinking water systems.
