The valves are used for smooth automatic control of the coolant flow in water heating systems. To perform the automatic control function and to achieve maximum efficiency, heating systems are used in tandem with a thermostatic head. Thermostatic 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 dismountable connection 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.
