Dual Double non return valve (DDNRV)
Dual‘s Double Non-Return valve operates on the discharge side of two pumps in parallel. Both pumps can run simultaneously or independently. When one pump is switched off, the ball will automatically drop back stopping the back flow to the other pump.
- Flush ports.
- As the elastomer covered ball moves, 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.
- Replaceable ball and seats.
