Kromschroeder 03089065 spring 120-220 mbar for JSAV50-JSAV100

Adjusting spring (upper limit response) Kromschroder 03089065 for SSV JSAV 50-100 (range 120–220 mbar). This is an original replacement spring from Kromschroder, designed for readjustment of the upper pressure limit trip threshold (pdo) of safety shut-off valves (SSV) of the JSAV 50, 80 and 100 series. Unlike pressure regulators where the spring sets the working pressure, in JSAV valves this spring determines the emergency threshold. When gas pressure exceeds the set limit (from 120 to 220 mbar), the valve trips and automatically shuts off the fuel supply, protecting downstream equipment (burner, regulator) from damage. If the valve trips too early (false lockouts), does not trip at dangerous pressure, or if protection needs to be adjusted to other gas network parameters — replacement with original spring 03089065 is necessary.
