Note: For optimum service life of the fittings, it is recommended to set the PS control pressure based on the medium pressure
- see control pressure diagrams. The PS control pressure may vary depending on the nominal diameter DN, diaphragm material
and function of the actuator.
If different control pressures are used in the system, it is recommended to use a pressure regulating valve. For the specific
dimensioning, please contact your representative at Georg Fischer Piping Systems.
