The ZSG 6 regulators are designed for set value differential pressure regulation and flow limiting. When installed, its input is connected to the return of technological installation.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 gases up to 80 °C.

• pressure difference control with flow limitation in installation that is connected in series to the controller.(housing on the return side)
• 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,
