The height of the adjusted auxiliary pressure influences the regulating procedure of the device.
To obtain a high precision of regulation, which is connected to a smaller closing pressure, an auxiliary pressure should be
adjusted as high as possible in the stabilization of the gas pressure regulation device.
According to the application the following advised values must be appplicated:
