The valves are used for smooth manual control of the coolant flow in water heating systems. MVI valves can be used on pipelines of drinking and domestic drinking systems, hot water supply, as well as on process pipelines transporting liquids that are not aggressive to valve materials. The presence of a half-grip ("American") allows you to mount and dismantle the valve without dismantling the pipeline. The main purpose of the valve is to regulate the flow of coolant through heating devices. Control valves are designed for custom flow control. Operating temperature - up to 110 ºС, pressure - up to 10 bar.
