What Nencini does

Nencini (legal name F. Nencini S.r.l.) is an Italian manufacturer founded in 1967 that designs and produces custom-engineered waterworks valves for hydraulic applications. Its 11-product portfolio serves regulation, dissipation, discharge, emergency, and security functions in water utility systems, hydroelectric power plants, dams, water treatment facilities, and desalination plants. Product lines include air valves, needle and axial flow control valves, butterfly valves, fixed cone (hollow jet) valves, sleeve valves, ball and spherical valves, check valves, gate valves, penstocks and stoplogs, multijet rotative valves, and dismantling joints. The company is headquartered in Cenate Sotto with a second site in Colle di Val d'Elsa, and operates with a headcount in the 11–50 range.

Nencini's engineering capability rests on traditional computer-aided engineering tools: Finite Element Method (FEM) analysis applied to ASME code standards, Computational Fluid Dynamics (CFD) for cavitation and hydraulic performance evaluation, and acoustic simulation software aligned with EN 60534-8-4. Each valve is engineered to project-specific requirements using a broad materials portfolio that includes ductile cast iron, cast carbon steel, aluminum bronze, stainless steels, structural steel, and special alloys such as Inconel and Monel.

The business model is private, project-based, and entirely direct enterprise field sales. Revenue is generated through one-time sales of custom valves plus aftermarket professional services spanning design support, commissioning, on-site inspection, training, maintenance, and spare parts. Customers are large engineering firms and infrastructure owners across Africa, Europe, the Middle East, South Asia, Oceania, and South America. Since 2022, Nencini has operated as a member of the OMB Valves Group, an international conglomerate that provides commercial and technical synergies for further development.

Functional benefit

Products and services

• Air Valves Air valves for raw, potable, sea, and sewage water, available in three types: air release valves, vacuum breakers, and combination air valves. They draw out air when the main pipe is filling, allow air into the pipe while emptying, release trapped air during operation, and avoid damaging surges with anti-slam devices.
• Needle Valve (Axial Flow Control Valves / Plunger Valves) Axial flow control valves/needle valves engineered for pressure and flow control, featuring significant reduction in turbulence, vibration, and noise, fine regulation of flow via customized trim, high precision control, and high rangeability.
• Butterfly Valves Butterfly valves designed and customized for hydroelectric power plants, available in concentric, double offset, and triple offset types. Suitable for raw, potable, sea, and sewage water, used as isolating devices with tight seal when closed and minimal pressure loss when open.
• Fixed Cone Valves (Hollow Jet Valves) Fixed cone valves that discharge water in free air, chamber, or underwater level, controlling flow with valve sleeve movement. Suitable for dissipating very high energy without cavitation when discharging in free air, customizable on demand.
• Sleeve Valves Sleeve valves used as by-passes for turbines or to draw water from dams, reducing excess head of inflow and discharging tamed outflow into stilling basin. Available in submerged vertical sleeve valves and double flanged sleeve valves.
• Ball and Spherical Valves Ball and spherical valves for hydroelectric power plants with high flow rates and/or pressures. Feature two movable sealing rings (upstream and downstream) ensuring perfect valve tightness, with the upstream ring serving as maintenance tool for the downstream ring.
• Check Valves / Non-return Valves One-way valves preventing backflow, available as axial check valves and flap non-return valves. Provide aerodynamic flow optimisation, low pressure losses, and highly responsive, surge-free operation.
• Gate Valves High-pressure dam outlet protection valves operating in maximum open or maximum closed positions, suitable for on/off applications. Nencini designs and manufactures slide, ring, or radial hydraulic sluice gates.
• Penstocks and Stoplogs Low pressure intake devices for canals, reservoirs, and basins, usually wall mounted. Stoplogs consist of several units lifted by a lifting beam. Available in structural steel (carbon or stainless steel) with various guide materials.
• Multijet Rotative Valves Multijet rotative valves consisting of a multi-hole plate assembled between two helix-shaped plates (fixed and rotating), providing downstream flow in evenly distributed jets. Controls flow between fully open and fully closed positions.
• Dismantling Joints Essential pipeline components offering ease of installation and maintenance, accommodating axial movements and slight angular deflections. Ideal for water distribution networks, desalination plants, dams, and hydroelectric power plants.
• Aftermarket Valve Services Comprehensive lifecycle services covering customer support design, project support, commissioning, on-site inspection, training, maintenance, and spare parts for installed valves.
