Coltri Pressure Maintaining valve Silver | Diveinn I exchanged all the o-rings on this PMV, now it works more or less.
Compressor produces 0 to 150 bar, PMV has a very small blow-by, nearly zero.
Compressor produces 150+ bar, filling hose has the same pressure.
When I stop compressor, we still have this small blow by. Within 10 min compressor has nearly zero bar.
I do not know if this is correct. I expected a hysteresis of perhaps 50 bar, compressor pressure goes down from 150 bar to 100 bar, then PMV closes compeltely.
Does anyone use this Coltri PMV and can tell me if this heaviour is normal? Thanks.
