Dual Dashley Valve (DDV)

Dual Dashley Valve (DDV)

Dual’s Dashley valve operates on the discharge side of two pumps in parallel. Both pumps can run simultaneously or independently. When both or one pump is switched off, the ball will automatically drop back stopping the back flow to the pump.

DASHLEY Features

As the elastomer covered ball rises or falls it rotates with the flow.

This ensures that the valve self cleans and permits it to open and close reliably even under severe conditions of slurry build up.

Minimal pressure drop.

Optional handwheel for isolation.
