Introduction

Flanged Ball Check Valves also known as check valves, its role is to prevent the flow of media in the pipeline. Open and close parts rely on the flow of media and force to open or close, in order to prevent the backflow of media valves called check valves.


Applications    

Pumping stations for clean, sewage water and loaded or viscous fluids.    


Technical performance    

Full bore ensured    

Self cleaning ball    

Low pressure drop    

Silent    

Removeable bonnet for cleaning or changing the ball with out disassembly out of the pipeline    

Horizontal and vertical installation in the pipeline  

  

Test    

Seat: 1.1x normal pressure    

Body: 1.5x normal pressure
