The ZSG 1 regulators are designed for set value pressure regulation in technological installation connected to the outlet of the regulation valve. Growing regulation pressure causes closing of the valve of 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 gases up to 80 °C.
for setting the reguired value of pressure, is situated outside the actuator.
the regulator valve remains opened when without energy supply.
