Main advantages of GUICHON VALVES’s piloted relief valves :

• Good tightness : the tightness is maintained until 98 % of the set pressure
• Quick opening : the useful overpressure to obtain full opening is lower than 3%
• Modulating operation : opening proportional to the overflow, therefore no throttling or pumping
• Stable operation : no adjustment or setting required on site
• Easy maintenance : elastomere seals, removable seat and top entry design for easy and quick intervention, disassembly not required, no special tools
• Factory adjusted pilot : no adjustment or setting required on site.
