The new Waukesha Cherry-Burrell D4PMO valve is designed specifically for the US dairy market in line with the latest 3-A sanitary standard 85-02 for Pasteurized Milk Ordinance (PMO).
The D4 Series valves, launched in 2018, are now used in the dairy, beverage, brewery, food, personal care, and other industries around the world. They offer separation of dissimilar products during continuous processing, with 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, such as 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 CU4plus control unit as standard. This unit has a fully integrated position and seat lift detection with internal sensors, which eliminates external wiring to avoid disruptive adjustments and potential damage during handling or washdown.
SPX FLOW said the D4PMO valve offers dairy businesses a budget-friendly solution to provide continuous and reliable processing, cleanability, and ease of maintenance.
The company said it also helps maximize plant uptime, allows flexibility in cleaning and dairy production schedules, and minimal CIP losses. It has a fully-balanced design for flexible flow direction without slamming and integrated flow channels for flushing the upper balancer during seat lift movement without the need for full actuation or additional external piping. It is further available in mixed sizes to fit complex installations with minimal piping rework.
The Waukesha Cherry-Burrell D4PMO is manufactured in the US at the SPX FLOW facility in Delavan, Wisconsin. It will replace the current WCB W75 Series within the SPX FLOW valve portfolio and is available with special body centerline dimensions to match existing W75 series valves for upgrade.
Accordingly, the W75 Series will no longer be available for sale after the end of 2020. Individual spare parts and service will continue to be provided to support existing installations.
