Description
The Bard HVAC 8603-006 is a 1-inch normally closed (N/C) 24-volt zone valve engineered specifically for geothermal HVAC applications. Designed as a genuine OEM replacement part, this valve ensures precise, dependable fluid flow control within geothermal heating and cooling systems, maintaining system efficiency and protecting equipment integrity.
As a normally closed valve, the 8603-006 remains shut in its de-energized state, preventing unintended flow and providing a built-in fail-safe for your geothermal loop. When energized at 24V, the valve opens to allow controlled fluid circulation through the system, making it ideal for zone control and loop isolation duties common in geothermal installations.
