Interior Title: 
Bulletin # 3 of 2009
Title Type: 
Change To Product
Bulletin Date: 
Bulletin # 3 of 2009 June 9, 2009
Bulletin Type: 
Change to Product Bulletin
Bulletin Subject: 
P/N 220-050 Inlet Valve
Products Affected: 
220-050, 205-015, 505-561, 525-217 and 525-718

The original Inlet Valve, P/N 220-050, and the Inlet Valve Assembly, P/N 205-015, have been modified to include a co-molded stainless steel balance chamber. The new part numbers with the modification are, 220-050SS, for the valve, and 205-015SS for the valve assembly (includes the silicone seat).

This modification is very obvious, as the stainless steel balance chamber is easily visible at the end of the part, (assembly). The change creates a slightly longer balance chamber that will allow finer adjustment when using supply pressures at the low end of the supply tables.

The new Inlet Valve Assembly part number, 205-015 SS, and the individual Inlet Valve part number, 220-050 SS, will be used strictly on SuperFlow® 450 regulator assemblies and associated kits, P/N 505- 561, P/N 525-718 and P/N 525-217.

The original Inlet Valve, P/N 220-050, and the Inlet Valve Assembly, P/N 205-015 are available and the ONLY approved parts, at this time, to be used on the NATO switchover regulator and pod assembly, P/N 805-001 and P/N 805-050. The modified parts will fit with this regulator, and will be used at a future date when official military approval has been issued.
