SUBJECT: Sudmo BAA S400FDV-IT Select Flow Diversion Valve, Equipped with Proximity Switches, Sizes DN 1", 1.5”, 2.0”, 2.5”, 3.0”, And 4"

In accordance with M-I-00-2, Milk and Milk Product Equipment-A Guideline for Evaluating Construction, FDA’s Central Region Milk Specialists and CFSAN’s Dairy and Egg Branch/Milk Safety Team have specifically evaluated the Sudmo BAA S400FDV-IT Select Flow Diversion Valve, Equipped with Proximity Switches, Sizes DN 1", 1.5”, 2.0”, 2.5”, 3.0”, and 4” and have validated and confirmed the technical information submitted by Sudmo North America, Inc.

The Sudmo Flow Diversion Device consists of two (2) Sudmo non-slamming compression-type divert valves (Type BAA S400) clamped together to form an assembly.  The assembly is used to enable the “Divert Flow”, “Leak Detect” or “Forward Flow” positions.  M-b-347 (Supplement 1) addresses the use of Sudmo BAA S400FDV-IT with an IntelliTop 2.0 Control Head that contains a proximity switch as the position detection device instead of a micro-switch as reviewed and referenced in M-b-347 (Sudmo BAA S400 Flow Diversion Device, Model 2000, DN 1"- 4" Inch). Adjustment procedures for the automatic setting of the proximity switch are outlined in the Manufacturer’s Operating Instructions BAA S400FDV-IT Select, Flow Diversion Valve, DN 1”-4”, Issue 5/13/2011/Version 2.01.

When constructed, installed, operated and maintained as described in this memorandum, the Sudmo BAA S400FDV-IT Select Flow Diversion Valve, Equipped with Proximity Switches, Sizes DN 1", 1.5”, 2.0”, 2.5”, 3.0”, and 4" has been found to meet the applicable provisions of Item 16p-Pasteurization and Aseptic Processing of the Grade “A” Pasteurized Milk Ordinance (PMO). Compliance with the PMO is based upon construction, installation, operation and maintenance as described in the Manufacturer’s Operating Instruction BAA S400FDV-IT Select Flow Diversion Valve, DN 1”-4”, Issue 5/13/2011/Version 2.01 and the IntelliTop 2.0 Control Head Operating Instructions, Issue 2010-2011, as well as the following provisions:

  1. The control system utilized with the FDD shall comply with Appendix H. of the PMO and shall be found acceptable to the State Regulatory Agency.

  2. The installation shall comply with all applicable tests cited in Appendix I. of the PMO.

  3. Appendix I., Test 5.4, Device Assembly, of the PMO, shall be conducted in accordance with the testing procedures cited in the Operations and Instructions Manual, provided by the manufacturer. 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.
