1. The context
One challenge in the field of chemistry, petrochemical or polymers is maintaining the fluid produced in the industrial lines at a specific temperature so that its properties can be conserved throughout the manufacturing process.

The valves are therefore subject to the same constraints : having a heating or cooling jacket that ensures the required temperature.

2. The operation

The jacket is supplied with a heat transfer fluid that can be either gaseous (steam) or liquid (oil such as Therminol 66 for example, which has a powerful capacity to produce heat). The supply of the heat transfer fluid can be done in several ways: via an injection port, directly to the flange, through welded ends, by a three piece connection, etc.

3. The Guichon know-how

Responding to customer-specific needs by custom made fabrication :

• Possibility of separate heating or cooling compartments on a same valve so that sections can be individually controlled = gain of operation

• Possibility of limiting the number of connections (piping, space and cost constraints) to heating jacket through guiding the fluid by a system of internal walls = easy installation

• Possibility to retro-fit existing valves with heating jacket = saving time and money

• Possibility to jacket the flange = better productivity

• Good management of volume and flow in the jacket thanks to 90 years of valve manufacturing experience : more than 7,000 jacketed valves designed and manufactured.

Provide a quality product in its design and manufacturing with a vigilance point welding : welding a jacket is a delicate operation that we harness perfectly = better tightness, maintenance and improved cost !

How Guichon Valves comes to the rescue of a Japanese customer!

It is the story of a plant shut down at an industrial site on the other side of the world (Japan). A line of production stopped by a damaged part and Guichon Valves who, in the interest of helping its Japanese customer, has no other solution than to manufacture the part and send someone to Tokyo for extreme emergency delivery.

It is the story of the die Master II (International marketing manager) from the University of Savoy (France), who seeks to fund her education seminar in Morocco.

What is the connection between these events, might you ask? Quite simply, the relationship between Guichon and the University of Savoy!

This is how Elodie Lesourd (student pf Master II) came to experience an out of ordinary adventure and bring her fellow classmates a long-awaited funding!

The piece of one meter in diameter, manufactured by Guichon in 48 hours, was entrusted to Elodie Lesourd one Friday evening for flight in direction Tokyo. The student therein delivered the part to our Japanese partner who installed it on the production line on Sunday. The plant was able to resume its activities first thing Monday. As for Elodie, she had the opportunity to enjoy a week-end in the Japanese megalopolis. As for Guichon valves, we were congratulated for their reactivity and the quality of the customer service provided. A completely successful operation!

Afterwards, students from the University of Savoy had the opportunity to visit Guichon Valves and receive an additional donation for the funding of the seminar by Managing Director Thierry Perrier.

“In addition to the standard applications for thermal and fluid analysis, SC Tetra can simulate a wide variety of phenomena such as chemical reactions, acoustic phenomena, … ” says SC Tetra on its site.

With this new software, GUICHON takes one more step in the fluid analysis and  thermal phenomena. We are now able to, study applications such as “fluidized bed” (gas+powder),and optimize our flush valves.

Experience combined with a technical expertise in fluid mechanics, in addition to conventional valve design, our R&D offers innovative solutions to the most diverse and complex valve problems through a personalised approach, regardless of the technology.

Our engineers rely on efficient design tools : 3D CAD software, FEA software, fluid mechanic and thermal simulation (bi-phase).

Two new employeed Bo-Shiun and Benedict have joined our team to strenghten our purchasing department :

T.Tedde & F.Manning promote the Guichon Valves brand on their site by valve types and industrial applications : Globe valves, Spray rinse valves, Cryogenic valves, Diverter valves, …

We relay the action of our Belgian agent Geert Thomas who highlights, via emailing, the sampling valve 655m of Guichon Valves:

Geert Thomas: “This is the new Guichon Valves sampling piston valve 655m (see the page). This sampling valve, which is used in many application areas (chemical, petrochemical, pharmaceutical, etc …) is available with body and internals in stainless steel A351 CF8M / 316. It is also available with a flush closing piston, a crust breaking position and an adjustable piston extension. Guichon Valves is able to perform most of the existing designs of sampling valves for removal of tank, reactor or online. “
