Two stage decompression units EN20 and EN50 series have their application in food, oenological and chemical field and industry. The main use is for the separation of the stored product from the atmospheric air. That avoid the oxidation of the product and, in case of polluting materials, the atmospheric dispersion due to evaporation or during the charging operations. Inlet pressure :

Excess pressure valve S2
S2 model is a self-operated fully balanced excess pressure relief valve. It’s used to maintain the pressure upstream of the valve to an adjusted set point. This excess pressure valve can not replace a safety valve. When upstream pressure rises above a set point, the valve opens proportionally pressure rising.
Application :
This model of regulator is suitable for steam, compressed air, no hazardous gases and liquids.
Regulation range :
20 mbar to 8 barg. with different actuators.
Diameters : DN15 to DN100
Flanges :
DIN PN16 – PN25 – PN40
ANSI 150 – 300Materials : Trim Stainless steel AISI 304, body in ductile iron, carbon steel or stainless steel 1.4408.
ATEX
Several models of excess pressire valves / dischargers exist (threaded, ISO, ANSI, liquid, gas, steam …), do not hesitate to contact us to discuss your needs.

Outlet flanged relief valve H810
Le modèle H810 est une soupape de décharge (déverseur) canalisée qui peut être utilisée sur les réseaux d‘eau potable. Application :
La soupape de décharge H810 est en général placée à l’aval immédiat des pompes sur une dérivation. Elle sert à éviter le “barbotage” des pompes à débit nul, lorsque la vanne ou l’appareil en aval est fermé totalement.
Sa fonction n’est pas de remplacer une soupape de sécurité.Plage de réglage :
1 à 25 bar eff. avec différents ressortsDiamètres : DN50 à DN150
(autres diamètres, nous consulter)Brides :
Bride d’entrée suivant norme 29203 : PN16 ou PN25
Bride de sortie : PN10Matières : Corps en acier, détails des matières sur la fiche PDF.
Attestation de Conformité Sanitaire (ACS), qui rend son utilisation possible sur les réseaux d’eau potable.
Plusieurs modèles de soupapes de décharge / déverseurs existent (filetée-taraudée, à brides ISO, ANSI, pour liquides, gaz, vapeur…), n’hésitez pas à nous contacter pour nous exposer votre besoin.

Changeover Valve – Model 5400
Changeover valves are a switchover valve, switching flow from one pipeline to another. They are sometimes referred to as “selector” valves. Changeover valves are well suited to applications where mandatory pressure relief devices (bursting discs and relief valves) are installed as dual devices. The design of the changeover valve 5400 ensure that at least one of the two pressure relief devices is always in service and full relief flow is guaranteed during changeover.
They are also widely used in Plastic and Polymer, Offshore, and Refining industries to handle process media
