Syntesi® pressure regulator is based on the rolling diaphragm principle, which offers numerous advantages compared to systems using a flat diaphragm:
The regulator includes a compensation system that keeps the pressure setting virtually constant, even when the upstream pressure changes.
This is achieved mainly by the the pneumatically balanced valve.
If the downstream pressure rises above the threshold value, the air is discharged (relief valve) until it drops below the maximum value.
A special device relieves downstream pressure rapidly when the upstream pressure drops to zero. This means the regulator can be positioned between a valve and a cylinder because the air can flow in
both directions, towards the cylinder with regulated pressure, or return towards the valve during relief.
