I have a pressurized CO2 setup which has been running well from the past 2 years. CO2 regulator is Eagle.
After every refill I used to setup the output pressure at 2kgs/cm2 by turning the regulator knob, and leave it at that until the next refill. Never touch the knob again until the next refill. I have a CO2 stop valve ( Ball Valve ) after the regulator, which I use to switch off the supply to the tank at night.
From the past few days , I see that the input pressure is dropping since the CO2 is getting over. I turn off the ball valve at night, and the output reading at that time reads 2kgs/cm2. Surprisingly, in the mornings when I see, the output pressure has shot up to 8-10 kgs/cm2. It slowly starts reducing after I let the CO2 into the tank by turning ON the ball valve.
I've been noticing the shoot up of the output pressure only from the past 4-5 days, since the time the input pressure started dropping.
Is this normal ?! Is a high input pressure required to restore the output pressure or pressure plates to it's normal value/position ?!
This morning I decided to experiment, and totally loosened the regulator knob ( i.e. Tried to shut down the output ). Then turned ON the ball valve. But the pressure only dropped from 8 kgs/cm2 to 2 kgs/cm2 and it's been at that value since morning. i.e. the CO2 supply never shut down even after removing the regulator knob.
Has the output pressure control plates in the regular got stuck or is it gone?!
Can anyone throw some light on this ?! ( Or the exact working of a CO2 regulator which can explain this phenomenon I am seeing ?! )
