Two new valves by Guidi Srl: a non-stick and a ball valve, developed in collaboration with the DITEN of the University of Genoa

Guidi Srl is the Italian leader specialized in the production of bronze, brass, chrome-plated, nickel-plated and aluminium nautical accessories. Founded in 1986 by Bruno Guidi, it manufactures non-stick valves, seacocks, thru-hulls, water strainers and fittings.

At the Mets Trade 2019, the company presented two world premieres: two innovative valves which are distinguished by remarkable seafaring quality and excellent characteristics of encrustation- and corrosion- resistance.

The new valves – a non-stick flanged and a full bore ball one – are in bronze and are specially designed to be used in the cooling systems of yacht engines.

Non-stick valve of the Alex series, flanged

Size: DN80, Art :2275new Guidi non-stick valves

Same technical features as the 2260 threaded series

This new valve features a body and cover made of CC491K bronze as well as a neoprene membrane to protect the mechanism.

Even the metal shutter is protected by a neoprene membrane to make this non-stick valve of the Alex series longer-lasting. The valve is suitable and highly recommended for use in marine environments

Full bore ball valve

new Guidi ball valveSize: from 1/4” to 2”

This full bore ball valve by Guidi features a body and a body end made of CC499K bronze as well as a ball in PPS, a semi-crystalline thermoplastic with excellent mechanical and chemical resistance properties that are retained at high temperatures. This valve, currently under production, is subject to a special surface treatment of the ball, to improve its encrustation-resistant properties.

The lever of this new product is in 304 stainless steel and the valve is equipped with an anti-blowout stem. The latter guarantees excellent encrustation- and corrosion-resistant results, as showed by the laboratory tests conducted at the DITEN of the Univeristy of Genoa. The product, in fact, proved to be extremely reliable in marine environments, also thanks to the functionality of the valve which allows the closure, opening and reduction of the flow.

The growth of Guidi

During the first ten months of 2019, Guidi has recorded 10% growth in turnover compared to the.same period of last year, with a balanced division between the Italian and foreign markets: particularly positive signals come from France, Spain, Poland, Middle and Far East.

In this respect, new Guidi valves, factorywe had the opportunity to interview Alessandro Guidi, Design Manager of the Italian company, who told us about the products and one of the future plans of the brand.

The Guidi 2400 valve is the first valve we entirely made in home. It features a body in CC499K bronze which can be used for drinking water. The main feature of the product is the material of the ball, a PPS base, a plastic material specially used to undergo alteration of the saline water. “

The manager also told us about the second valve presented at the METS: ” The Guidi 2275 valve, in the DN80 size, has the same features as the 2260 but with a flanged body. We started from this size following a request from one of our customers, and from here we will get to the DN65 size. Then, we will certainly move on to DN50 and DN40, for which we will use the same mechanisms of the Alex valve and therefore just create the body. Moreover, a larger valve is in the pipeline but we are still studying the type. “
