Description
Kromschroder adjusting spring (response spring) 03089071 is a spare part for safety shut-off valves JSAV 25 and JSAV 40. It is used to set the trip threshold for the upper pressure limit, with an adjustment range of 100–210 mbar. The factory setting is 120 mbar. Made of spring steel, it weighs approximately 0. 02 kg (20 g) and is dark green in color. This spring protects downstream equipment from damage by triggering valve shut-off when gas pressure exceeds the set limit.
Further details
| Application | natural gas, liquefied gas (propane-butane), biogas, air |
|---|---|
| Calibration | guarantee consistent calibration and safe burner operation |
| Compatible valves | JSAV 25 (1"), JSAV 40 (1½") |
| Fatigue effect | can cause drifting outlet pressure, leading to unstable firing or lockout |
| Function | sets the emergency threshold in safety shut-off valves |
| Inspection | check for corrosion, deformation, or loss of temper |
| Installation procedure | set the preload according to the valve manufacturer's adjustment procedure |
| Replacement reason | false lockouts, dangerous pressure, adjustment to other gas network parameters |
| Service part | used to restore or adjust the gas valve's regulation performance |
| Spring function | presses against the diaphragm to maintain stable downstream pressure |
| Spring selection | stiffer spring shifts range upward, weaker downward |
Choosing and fitting
Parts of this type are selected by matching the valve model and the required pressure range. Before ordering, verify the valve connection size (1" for JSAV 25, 1½" for JSAV 40) and the desired trip threshold. Installation involves replacing the old spring and adjusting the preload according to the manufacturer's procedure.
Signs of failure
A fatigued or corroded spring can cause the valve to trip too early (false lockouts) or fail to trip at dangerous pressures. This may result in unstable operation or lack of protection. Check the spring for corrosion, deformation, or loss of temper during service.
