B. DURING
The spring used in products is designed to provide desired output pressure intervals. For output pressures outside the specified range, a
spring change will be required. These springs must be supplied from the manufacturer.
- If required for various reasons, the output pressure of the product and safety closure pressure settings, if any, should be made as
follows:
1- The settings shall not be changed at a rate more than ± 10% and/or outside the limits specified on the label.
2- Seals on the related sections of the product, if any, shall be removed.
3- While adjusting the pressure, the adjustment mechanisms and springs should not be compressed, bent and forced excessively.
4- To see the values of the settings, connect the pressure gauge or manometer to a suitable test valve located between the product
and the output pipe and monitor the pressure by consuming gas within the appropriate capacity range.
5- For all adjustments to be made, pressure increase is achieved in clockwise rotations and pressure decrease in reverse rotations.
6- If there is an SSD, an increase in safety pressures should be ensured when adjusted output pressures are increased and a decrease in
safety pressures should be ensured when reduced.
- OUTLET PRESSURE SETTING:
1- Remove the relevant seal, if any,
2- Remove the "SR TOP COVER PLUG No. 1" by manually rotating it counterclockwise,
3- Turn the "SR REGULATION ADJUSTMENT SCREW No. 2" in the appropriate direction with the appropriate hexagonal wrench, (turning
counter clockwise reduces the outlet pressure; turning clockwise increases the output pressure.),
4- Mark the adjustment pressure being set,
5- After the procedures; Manually replace "SR TOP COVER PLUG No. 1" to its initial position.

- RELIEF (Regulation) PRESSURE SETTING
1- Remove the relevant seal, if any,
2- Remove the "SR TOP COVER PLUG No. 1" by manually rotating it counterclockwise,
3- Turn it in the appropriate direction with the hexagonal wrench suitable for "H1 TEMPER NUT No. 9",
4- Mark the adjustment pressure being set,
5- After the procedures; manually replace the "SR TOP COVER PLUG No. 1" to its initial position.
