Product Description

This valve is a key actuator in the regional control system. In the event of a power outage, the valve remains permanently closed by relying on its internal spring mechanism, blocking the flow of water and thus closing the corresponding area. When the control system issues an opening command, the 24V AC power is connected, and the internal synchronous motor rotates slowly, driving the waxy material inside the thermal element to expand, gradually and smoothly pushing open the valve core, thus opening the valve and allowing the medium to flow to heat or cool the corresponding area.

Its ** welded NC** feature means that the valve body adopts a welded design, which is structurally robust and suitable for installation scenarios that require higher sealing and durability, effectively reducing the leakage risk that may occur in threaded connections. The brass valve body ensures excellent corrosion resistance and a long service life. The 1-inch interface size makes it suitable for mainstream medium-flow pipeline systems.

The V8043E1079/U24V model integrates reliable thermal power technology and quiet motor drive, achieving silent and smooth switching actions and avoiding water hammer impact. It is often used in conjunction with Resideo or other compatible thermostats and zone controllers, and is a key component for enhancing building energy efficiency and achieving personalized comfort control. Its design focuses on the degree of integration with the system
