Non-return Valves

Non-return axial valves : one-way valves allowing the fluid to flow in only one direction and preventing the backflow.

Main features

■ optimization of the aerodynamic flow
■ path through the valve, which allows
■ little pressure losses
■ highly responsive non-slam operation.

Nencini valves work perfectly in very demanding operating condition.

Applications 

■ prevention of reverse flow
■ prevention of water-hammer
■ pump protection.

Customization on demand.

Technical Data

Size DN 100 <> 1500
DN 4“ <> 60“
Pressure range PN  10 <> 100
ASME/ANSI  150 <> 600
Actuation It remains in open position during normal flow.
A drop in the flow rate causes the spring to move, thereby closing the valve.
