Reliable Performance 

The D4PMO has the following features standard: 

  • 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 
  • Range of control units and bus communication for automated operation 
  • No compressed air needed for removal and servicing 

 

Cleanability: 

  • Designed to the latest 3-A Sanitary Stanard 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.
