Regulation range :
de 20 mbar to 6 barg

Aluminium / Laiton Inox

1/2″ VSF160 VSF3160

1″ 2VSS3 3VSS3

2″ VSF190 VSF3190

Connections : with flanges EN, ISO, ANSI ; DN15 to DN200 MODEL S1

Regulation range :de 20 mbar to 15 barg MODEL S2

Some other type of pressure excess valves (BSP, NPT, ISO or ANSI flanged, for liquid, gas, steam…) may reach your need, feel free to contact us.

Excess pressure valve S2

Accueil » Protection against pressure and vacuum » Excess flow valves, Relief valves

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 – 300

Materials : 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.
