Cutting-Edge Technical Expertise
Over the years, Guichon has developed sharp and unique technical expertise. We are thus able to model the behavior of single-phase or multi-phase fluids, simulate and verify material resistance to pressure and forces induced by installations (piping, etc.), and determine the best solutions to limit erosion caused by fluid velocity and/or composition. We also have a database of over 40,000 drawings at our disposal.
Expertise and Know-How
“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.

Among our recently completed, notable products are:
- “Double block and bleed” valve with parallel seats for large diameter Decoking applications in the petrochemical industry. (Label of Innovation “Oséo ANVAR”-2004)
- “Rigid” slide gate safety valve with less than 0.1mm deformation of sealing surfaces during service
- Piloted safety valve “anti-water hammer” for a line of unloading ammoniac at -32°C
- High pressure check valves with a low pressure drop.
- 4-way piston valve for fluid with high particle content (+20% abrasive particles).
- Multi-port selector sampling valve (12-way) on a primary circuit for nuclear application.
- High temperature ball valve (700°C) for abrasive powder.
- Ultra Compact double gate valve (2 valves in the space of 1).
- …
The expertise of the team (over 80 years of accumulated valve experience) is complemented with the use of high-performance computer tools for design: 3D CAD software, finite element analysis software and fluid mechanic and thermal simulation/ calculation software.”
