FAILURE TYPE PROBABLE CAUSE SOLUTION
Regulator does not work as
required The pressure intended to be adjusted may be outside the
installed broadcast range. Change springs.
The flow capacity of the line may exceed the product
capacity: Change product.
Signal lines may be clogged or in the turbulence area. Change the signal line.
The ventilation hole may be clogged or constrained. Clean the ventilation hole and take measures.
Regulator does not close
completely The diaphragms may be defected. Change the diaphragms.
A worn out, damaged, contaminated or carved flap. Clean the flap.
The O-ring may be worn out. Change the o-ring.
The o-ring nozzle may be worn out. Change the o-ring nozzle.
No gas in regulator Gas may not flow to the product. Check the gas installation before the regulator.
The SSD may be off. Unlock SSD.
Inlet pressure may not be available. Check the inlet pressure.
Regulator provides wrong
output pressure. Regulatory spring may be wrong. Replace with appropriate spring.
The required output pressure may be outside the output
pressure range of the product. Change the regulator model.
Inlet pressure may be low. Check the gas installation
The output pressure is equal to
the input pressure without any
flow rate in the regulator.
And
The output pressure in the
regulator is equal to the input
pressure in the operation
(while flowrate is present).
And
There's gas release from the
air-inlet connection in the
regulator. The signal line may be shut down. Check the signal line.
The signal line could be leaking. Seal the signal line.
The control plate may be damaged. Change the control plate.
The control plate slot may be damaged. Replace the control plate slot.
The operation diaphragm may be damaged. Change the operation diaphragm.
The balancing diaphragm may be damaged. Change the balancing diaphragm.
The lever is damaged. Change the regulator.
The o-rings of the regulator may have been damaged. Replace the regulator's o-rings.
The o-rings of the SSD may have been damaged. Change the o-rings of the SSD.
The balancing unit may be damaged Replace the regulator plate.
The o-rings of the balancing axis may be leaking. Change the regulator.
When the flowrate is increased
in the regulator, the output
pressure decreases.
And
Low output pressure outside of
tolerances is observed in the
regulator The intended volume flow may exceed the regulator's
performance. Check that the wrong product is not selected in terms of flow
rate and output pressure, change the regulator model.
The dimensions of the gas line may be incorrect. Increase the nominal width of the pipeline.
The gas filter before the regulator may be contaminated. Carry out maintenance on the gas filter, replace the filter.
The lever may be damaged. Change the regulator.
The signal line may be shut down. Check the signal line.
The SSD may be damaged. Check the SSD.
The input pressure may be incorrect. Check input pressure
The output adjustment pressure may be set incorrectly. Measure the output adjustment pressure, correct if incorrect
Filter may be contaminated Change the filter.
The problem may not have been detected. Replace with a new product.
Gas discharge from the air inlet
connection of the regulator. The operation diaphragm may be damaged. Change the operation diaphragm.
The balancing unit may be damaged. Replace the regulator plate.
The o-rings of the balancing axis may be leaking. Change the regulator.
The SSD cannot be
opened/activated.
The signal line may not have been installed or operated
correctly. Assemble the signal line.
The signal line may be clogged. Clear the signal line.
The signal line could be leaking. Seal the signal line.
The signal line may have been bent. Change the signal line.
The signal pressure may be out of the adjustment range. Adjust the shut-off pressure or output pressure of the SSD.
Adjustment springs may not be appropriate. Replace the adjustment spring.
The adjustment range of the SSD is outside the output
pressure. Change the SSD.
The SSD does not activate or
does not operate.
The signal line may not have been installed or operated
correctly. Connect/mount the signal line.
The signal line may be clogged. Clear the signal line.
The signal line could be leaking. Seal the signal line.
The signal line may have been bent. Change the signal line.
The signal pressure may be out of the adjustment range. Set the shut-off pressure of the SSD.
Adjustment springs may not be appropriate. Change the adjustment springs.
Failure can be caused by jams in the mechanism. Change the SSD.
The SSD shuts down but
doesn't seal.
The valve disc may have been damaged or worn out. Replace the valve disc and the flap or contact the
manufacturer for repairing.
The valve slot may be damaged. Replace the valve slot.
Moving parts may be contaminated by foreign
substances. Clean moving parts or replace the valve disc and flap.
The trigger mechanism may be damaged. Change the SSD.
That o-ring may be damaged. Change the o-rings.
SSD is leaking.
The operation diaphragm may be damaged. Change the operation diaphragm.
The SSD enclosure may be damaged. Replace the SSD enclosure.
Orifis-flap may have been worn out. Replace orifis-flap.
The flap o-ring may have been damaged. Change the o-ring.
