Vacuum Breakers
OPW Vacuum Breakers for high-pressure
applications permit quick, positive evacuation of the arm after the loading
operation is complete. A three-hole quill extends into the liquid passage,
forcing the flow pressure to hold the poppet closed while loading. This prevents
aeration of the product and leakage during loading. Liquid trapped in the
arm would add extra weight to the arm, causing it to move slowly. The 476SA
model is available in aluminum with stainless steel internal parts. The 489
model is stainless steel for severe applications and tough liquids.
