The ZSG 7 regulators are designed for set value differential pressure regulation in technological installation connected to the input of the valve regulator.This type of regulator can be applied in central heating systems and in indrustrial processes, for regulation of the flow of cold or hot water up to 150 °C, or of incombustible gasses up to 80 °C.

• pressure difference control in installation that is connected in parallel to the controller.
• the regulator valve remains opened when without energy supply
• high control accuracy,
• single ported with the pressure balanced plug,
• large diversity of connectors; easy mounting
