General :Nencini Co. since 45 years is a private manufacturer of special valves for hydraulic purposes, as drinking waterplants, irrigation, discharge of dams, hydraulic power plants, sea water plants and oil plants only for controlvalves.Nencini has proper design and technical department, quality control dept, production dept, Ansyscalculation dept, and a workshop with a big size of tools machines.
Experience:The experience of Nencini Co. since 40 years is supported from historical record of hydraulic tests carried outon site of works, in our workshop and with samples from Hydraulic University Laboratories, or hydraulicinternational laboratories ( as DELFT).
Special valves:Our valves are designed to resolve properly specific problems involved in the plants for every plant.These valves are special for type, size and working performances.
Technology:A lot of valves are supplied with control units for flow, pressure, level.These control units can have local electrical board with PLC and suitable for BUS connection fordistance control panel.The Engineering of HPU (Hydraulic Power Unit) and Electric Control Panel is made from ourCompany.
Machine Tools:The workshop of Nencini has big size of machine tools as vertical late, boring machine and weldingmachine with submerged arc with a rotating plate up to 5000 mm, in our workshop we are able to machine valvesup to 4500 mm of size.Two sister companies with bigger machine tools and a crane of 250 Tons are working with ourcompany under our design, our purchasing dept and our quality control dept, and are able to manifacture valvesup to 5500/6000 mm.
Workshop test.Our Company carries out workshop test of all valves manufactured from smaller sizes up to biggest.
Quality Control Dept:Nencini is qualified ISO 9001 : 2000 by DNV.
Materials and components:The materials used for the manufacture of valves are as follows:Ductile Cast Iron with proper wooden modelGrey Cast Iron with proper wooden modelCast Carbon Steel with proper wooden modelAluminium bronze with proper wooden modelStainless Steel with proper wooden modelStructural steel by welding systemStainless Steel by welding systemElectric Actuators Rotork - AumaHydraulic hoists Best International productionHPU Italian qualified suppliersElectronics CGE - FANUC - OTHERS
