Low-noise models with improved noise characteristics. Achieves stable pressure control over a wide range of flow rates and also works as a safety valve. The main circuit pressure can be controlled remotely by connecting a relief valve for remote control to the vent port. High-vent type options are available.
Use for a lower pressure setting in some circuits than in the main circuit. SGB valve maintains a constant pressure at the secondary side even when the pressure in the primary side main circuit changes. The branch circuit pressure can be controlled remotely by connecting a relief valve for remote control to the vent port.
