• Manufacturer: Nelsen Corp
• Part number: CL-DLFC-200-75 (alternate V3158-04)
• Outlet: 3/4" MPT (male pipe thread)
• For: 2" control valves
• Configuration: without silencer
• Function: drain line flow control (DLFC) fitting

The drain line flow control governs how fast water leaves the valve to the drain during backwash and fast rinse, which in turn sets the bed expansion that lifts, tumbles, and cleans the filter media. Using the flow control matched to the valve size, tank diameter, and media keeps backwash effective without wasting water or under-lifting the bed, which would leave trapped iron, sediment, or fines behind. This assembly threads onto the drain port of a 2-inch valve with a 3/4-inch MPT connection and ships in the no-silencer configuration for installations that do not require noise damping. Confirm the required flow-control button rating for your tank diameter and media before installing, and match the 2-inch valve fitment. A direct service part for large residential and commercial systems.
