Anti-freeze Valve Manufacturers _ How Tap Water Anti-freeze Valves Work

2022-08-03

Anti-freeze valve manufacturer—The municipal water anti-freeze valve features a built-in temperature-sensitive element that directly interacts with ambient temperatures, controlling the opening and closing mechanism between the piston and valve seat. When the ambient temperature drops below the set threshold, the thermal element contracts, pulling the piston downward to open the drain passage, allowing a small trickle of water to escape continuously. This steady flow prevents pipes from freezing. The municipal water anti-freeze valve operates autonomously via a temperature-sensing bulb, enabling self-powered opening and closing without the need for external energy, thus ensuring the stable operation of the water system.
