Pressure control valve

The KNF diaphragm pressure valve can be used to keep the system pressure constant, as a pressure relief valve to reduce pressure peaks or to prevent the media from being sucked directly through the pump. This accessory can be used in combination with a KNF diaphragm pump or as a standalone product.
