D4PMO Series - Double Seat Mixproof Valves

Used for the reliable separation and continuous processing of dissimilar fluids in Grade A dairy, the D4PMO Series helps fulfill today’s customer demands.

Features & Benefits

D4PMO Series Mixproof Valve Technology

The next generation of mixproof valve technology is the result of continued development from both APV™ and Waukesha Cherry-Burrell™ process technologies. Used for the reliable separation and continuous processing of dissimilar fluids in Grade A dairy, the D4PMO Series helps fulfill today’s customer demands for production flexibility, high productivity, rapid return on investment (ROI), and enhanced product quality across various applications in the fluid milk, cheese, cream, whey, and yogurt industries.

High Value, Low Life Cycle Costs

Newest generation continuous process PMO valve helps maximize plant uptime and allows flexibility in cleaning and dairy production schedules
“All In” standard features provide exceptional value and help to increase ROI to align with customer budgets
Reduced inventory costs with same seal kit used on multiple size ranges such as one kit for 1.5" - 3.0" sizes
Minimal CIP losses improve cost savings
Low air consumption and air supply requirements
Long housing ports ease manifold building
Integrated shaft seal flush reduces need for external piping
Mixed sizes and legacy centerline dimensions available to fit complex or existing installations with minimal piping rework

Reliable Performance

Innovative control unit design for fully integrated position and seat lift detection without external sensors
Fully balanced design helps to prevent hydraulic blocking, withstand pressure spikes, and enables flexible flow direction without slamming
Light overall weight helps support handling without lifting tools
Slim stainless actuator is fully enclosed to prevent fluid ingress
No compressed air needed for removal and servicing

Cleanability

Designed to the latest 3-A Sanitary Standard 85-02 for PMO compliance
Demonstrated ability to clean product-contact surfaces without full actuation of the valve
Integrated flow channels clean product-contact portions of the upper balancer during seat lift movement so no cumbersome adapters or external piping are required
