Back pressure regulators

A back pressure regulator or excess pressure valve is used to regulate a upstream pressure or discharge an excess pressure in the facility.

An excess pressure valve can not replace a safety valve.

Connections :
BSP / NPT
1/2″, 1″, 2″

Regulation range :
de 20 mbar to 6 barg

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 – 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.
