Guidi Srl Guidi è unicità e passione
Produciamo accessori nautici dal 1968: ricerca, innovazione, creatività Nel corso degli anni l’azienda deposita 13 brevetti.

L’avventura della Guidi inizia nel 1968, quando Bruno Guidi fonda l’azienda e comincia a produrre articoli di raccorderia e valvole. Ben presto l’azienda approccia un settore che ne segnerà il percorso futuro in maniera determinante: la nautica, un mondo affascinante e ricco di prospettive.

È una storia di qualità, innovazione e passione per il proprio lavoro. Bruno Guidi inizia a produrre accessori nautici, che subito si contraddistinguono per la loro durata, la sicurezza e per l’alto livello di tecnologia impiegata. Nel 1982 presenzia per la prima volta al Salone Nautico Internazionale di Genova. Dagli inizi degli anni Novanta espone anche al METS di Amsterdam. Partecipa inoltre alle fiere di Singapore, Brisbane, Las Vegas, Miami e Fort Lauderdale. Gli anni 2000 vedono l’inserimento in azienda della seconda generazione, Daniele e Alessandro, figli del fondatore Bruno, ancora saldamente al timone con entusiasmo ed energia. Oggi la Guidi è un’impresa all’avanguardia, dinamica e attenta all’evoluzione del mercato, capace di rispondere con grande professionalità e competenza alle mutevoli necessità della propria clientela. I maggiori cantieri italiani ed esteri e i distributori nautici ripongono la propria fiducia nei prodotti Guidi. La coerenza con principi e valori tradizionali, ma sempre attuali, la gestione delle risorse umane come patrimonio fondamentale e i sistemi di produzione all’avanguardia fanno della Guidi una protagonista di prim’ordine nel panorama nautico internazionale. Dal 2007 l’azienda ha deciso di comunicare la propria immagine attraverso l’arte, avviandola verso un percorso di mecenatismo industriale. Ancora una volta, una scelta all’avanguardia, conforme ai principi di sviluppo e costante innovazione che da sempre differenziano la Guidi dai propri concorrenti.

When in doubt, check first

Through-hull fittings, valves, sea intakes, and hose fittings work in critical points of the boat.
Before choosing or installing a component, it is important to check:
– application
– position in relation to the waterline
– material
– accessibility
– hull requirements
– applicable standard

👉 If you have doubts, contact us before installation.
A technical discussion can prevent mistakes that are difficult to correct later.

Measure before the problem becomes obvious

Many circuit anomalies become visible only when they start producing consequences.
Being able to measure what is happening along the path changes the approach.
In the C-PIN version, pressure sensors upstream and downstream of the water strainer make it possible to compare two points in the circuit. Temperature monitoring and detection of trapped air are added to this.
Data does not replace maintenance. It does, however, make it possible to observe conditions that would otherwise remain hidden until a symptom appears.

👉 A connected system is not only about control. It is also about understanding what is happening.

Statement: a declaration for product groups

A Statement is a generic declaration. It is drawn up for homogeneous product groups and certifies compliance with specific guidelines or requirements.
It must not be confused with an individual certification or with testing on the single piece.

👉 Every technical document has a precise scope of validity.

The same number does not identify the same thread

3/8" BSP and 3/8" NPT carry the same nominal value.
They are not the same thread.
They belong to different standards and differ in key geometric parameters, including thread profile, pitch and taper.

For this reason, converting or comparing the nominal value is not enough to establish whether two components can be connected correctly.
This is why a 2300 with BSP connections and configurations intended for U.S. standards with NPT/NPS connections should not be considered interchangeable simply because they show an apparently equivalent size.

👉 The nominal size is one piece of information. The standard completes its meaning.

Non-stick valves: the problem often starts while the boat is sitting still

A valve may remain in the same position for weeks or months. Seawater, however, keeps acting on it.
Corrosion and deposits can affect exposed internal parts and progressively make the mechanism harder to move.
In Guidi non-stick valves, the construction principle is different: a neoprene membrane separates the internal mechanism from the water and from galvanic current.
This does not mean eliminating wear or maintenance. It means protecting the part that must still move when the valve needs to be operated.

👉 Designing against seizure means acting on the cause, not on its consequences.

Type approval: what it is

Type Approval, or type approval, is a procedure for approving the design of a product.
It includes the evaluation of:

• design
• technical drawing
• prototype
• testing

Once the design has been approved, the type approval applies to subsequent products with identical design.

👉 It does not only concern the finished product. It concerns the way that product is designed and validated.

Cavitation: material is not the first cause

When surfaces damaged by cavitation are observed, it is easy to focus on the material.
But the phenomenon starts earlier.
Cavitation is linked to local pressure variations in the fluid, which can be influenced by component geometry and by the way the flow is accelerated, diverted or disturbed.
Material comes into play afterward: it can influence how well a component resists erosion caused by bubble collapse, but it does not remove the hydrodynamic cause of the phenomenon.

👉 Before asking how well a material resists, it is necessary to understand why cavitation is occurring.

Accessible does not mean readily accessible

The standard distinguishes between two important concepts.
“Accessible” means that a component can be reached for inspection, removal, or maintenance without removing fixed hull structures.
“Readily accessible” means that it can be reached quickly and safely, even in an emergency, without tools.

👉 In a marine system, the position of the component is part of safety.
