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 design of the valve, which is pneumatically balanced.
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.
The knob is push-lock type – once the pressure has been set, press it and it locks in position. In this position you can pull out the plate and attach one or two padlocks to prevent manipulation.
There are two 1/8 ” ports, one on the front and one on the back, for use with pressure gauges or pressure switches or, considering the high flow rate, as additional regulated air take-off.
