Radiator cranes with polypropylene casing are used for smooth control of coolant flow in devices for heating water heating networks. Cranes can be used on pipelines of drinking and domestic purposes, hot water supply, as well as on technological pipelines transporting liquids that are not aggressive to the materials of the crane. The presence of a polusgon allows you to mount and dismantle the valve without dismantling the pipeline. The main purpose of the crane is to control the flow of coolant through the heating
appliances. The crane is equipped with a special rubber insert, thanks to which, when mounting, the use of additional means of packing (tow, teflon, etc.) is no longer required.
