Nelsen WS3 DLFC Assembly NPT$371.26
描述
Nelsen WS3 DLFC Assembly with NPT connection is the drain-line flow control group that meters backwash and rinse flow on 3-inch WS3 commercial control valves.
- Drain Line Flow Control (DLFC) assembly for the Nelsen WS3 3" valve platform
- NPT (National Pipe Thread) drain outlet for threaded pipe or fitting connection
- Holds backwash flow to a fixed rate so the media bed lifts and rinses correctly
- Part of the valve's drain circuit during regeneration and backwash cycles
- Shipping weight roughly 2.8 kg, reflecting the larger commercial-scale body
- Genuine Nelsen replacement part matched to the WS3 valve series
Use this assembly when servicing a large-diameter WS3 system and the existing drain-line flow control is worn, cracked, or fouled, or when converting the drain to an NPT-threaded connection. Correct DLFC sizing is what keeps a commercial media bed backwashing at the flow it was designed for, so match the assembly to your original valve build before installing.
