The Sudmo BAA S400 Flow Diversion Device, Model 2000 when constructed, installed and operated as described in this memorandum; has been found to meet the applicable provisions of the Grade "A" Pasteurized Milk Ordinance (PMO).

This piece of equipment is a dual stem Flow Diversion Device (FDD), which has been designed to comply with Item 16p (B) of the PMO. The technical designs submitted to FDA for review were for 1"- 4" inch FDDs.

The manufacturer shall provide a spacer (0.059 inches/1.5mm wide) to facilitate conducting this test in the required manner.
  4. Upon proper installation and the determination of compliance through appropriate PMO testing, regulatory seals shall be applied through the handle of the manual air shut-off valves and around the valve body. The seal shall be sufficiently tight to assure that the manual shut-off valve cannot be closed without breaking the seal.
