The D4PMO is designed specifically for the U.S. dairy market in line with the latest 3-A sanitary standard 85-02 for pasteurized milk ordinance (PMO). The new valve is part of the company’s D4 range, which offers reliable separation of dissimilar products during continuous processing with ensured separation of clean-in-place (CIP) fluids. The D4PMO is based on the design of the core D4 mix-proof range with additional features to meet PMO standards. These include maintaining zero pressure within the vent cavity and the impingement of CIP fluid during seat-lift operation. To manage seat-lift detection, the D4PMO valve includes the company’s CU4plus control unit as standard. This unit has integrated seat-lift detection with internal sensors, which eliminates external wiring to avoid damage during handling or washdown. For ease of installation and service, the valve uses a common seal kit across multiple size ranges.
