This motorized brass globe valve combines durable brass construction with automatic flow control for heating, cooling, and fluid distribution systems. It integrates a 2wire AC 220V actuator and is a twoway shutoff valve. Available in DN15, DN20, and DN25 sizes, including the DN25 model specified as 220VAC_2 WAY in the listing. Key benefits Precise automatic flow control: quickly modulates valve position to regulate temperature and flow in your system. Simple 2wire 220V installation: easy wiring to standard control circuits and building automation equipment. Durable brass body: robust construction designed for reliability and long service life in hydronic and process applications. Spacesaving twoway design: streamlined installation with straightforward shutoff and flow control. Reliable shutoff performance: ensures tight closure when the valve is closed to prevent unwanted leakage. Wide applicability: suitable for residential, commercial, and light industrial piping networks that use brass fittings. Key attributes Functionality: motorized globe valve with integrated actuator, twoway shutoff flow control. Material: brass valve body for durability and corrosion resistance. Size options: available in DN15, DN20, and DN25 to fit a range of piping systems. Actuator and wiring: 2wire AC 220V operation for simple electrical connection.
