SUBJECT: Waukesha Cherry-Burrell W75RS PMO Double Seat Mix-Proof Valve 1"-4" inch (Spill-Free Design)

In accordance with M-I-00-2, Milk and Milk Product Equipment-A Guideline for Evaluating Construction, the Food and Drug Administration's (FDA) Central Region Milk Specialists and CFSAN's Milk Safety Team have evaluated this Mix-Proof Valve and have validated the technical information reviewed and submitted by the Atlantic-Midwest Dairy Equipment Review Committee (AMDERC) addressing the Waukesha Cherry-Burrell W75RS PMO Double Seat Mix-Proof Valve 1"- 4" inch (Spill-Free Design). When constructed, installed and operated as described in this memorandum, this Mix-Proof Valve has been found to meet the applicable provisions of the Grade "A" Pasteurized Milk Ordinance (PMO), when used to separate cleaning product solution and milk and milk products.

Waukesha Cherry-Burrell W75RS PMO Double Seat Mix-Proof Valve 1"- 4" inch (Spill-Free Design) is a single-bodied double seat valve designed to comply with Item 15p. PROTECTION FROM CONTAMINATION, 15p(B) of the PMO. The valve may be used as part of a fail-safe system to separate milk and milk products from tanks or circuits containing cleaning and/or sanitizing solution.

Compliance with the PMO is based upon construction, installation, and operation as described in the manufacturer's Operation and Maintenance Manual, October 2004, publication #95-03076.
