Since  1967 Nencini Co. manufactures valves for water under proper design and under main international standard.

 With our analytical method and with finite elements computation software (ANSYS) , Nencini Co achieved high level on the design so,  with experience of forty years, product manufactured  have high standard of quality and a very good reliability for the construction and performances.

 First aim of Nencini was and is to have a product completely Italian for basic materials and castings and manpower.

 Our workshop is the center of all constructions, but some components designed from Nencini are manufactured outside around of Nencini, every in Italy, as hydraulic pistons, hydraulic power unit, electric board panel, flanges, castings, rolled sheets.

Electrical actuators are made in UK or in Germany.

 Our policy  in the construction of every our product is to have a grade of safety very high, so our guarantee could be extended up to 12/24 months  without any problem.

 Nencini Co is a world leader for Flow Control Valves, Johnson type, with internal gearbox located in a dry chamber and for Butterfly Valves with counterweight as on-off valve for hydraulic power plant.

Nencini  be archived with experience and design the possibility to manufacture Discharge valve with capability to have a very high headloss and by way to destroy energy only as some valve, without consultation.

These valves, as submerged sleeve assembled an steel basin or double flanged sleeve assembled on line, have the capability to destroy energy up to 20/25 MW.

Other product is our main production is Air valves, a Air vacuum, Air Rlease and all valves connected with is air problems.

Our production has been every interested  to special valves, like largest sizes, high pressure range, particular performances.

 Our collaboration with main  Consultant Companies to resolve some particular hydraulic  problems is our  main pride.

 Some particular models of our valves has been tested on Hydraulic Laboratories of main  important Italian Universities and after manufactured.
