RTG 411 regulators are of indirect action type and are used for reducing and regulating the pressure of non-corrosive gases (natural gases, LPG, etc.). The regulators ensure constant maintenance of outlet pressure within the limits of the regulation class, irrespective of the fluctuations of inlet pressure and flow rate. They are designed for natural gas transportation and distribution networks. RTG 411 regulators can be used for all installations with rapid variations of the flow rate. The highly special performance of the pilot system ensures pressure accurate regulation and regulator rapid response.
