IW series antifreeze valves are designed for installation in systems using monobloc heat pumps to protect them against thickening of the fluid and freezing. The three-piece design simplifies servicing—the foot valve is installed between the valve body and the insert.
Features
- Brass body and thermal element,
- Operation within a narrow temperature range,
- The foot valve ensures reliable, tight shutoff,
- Operates only in response to temperature changes,
- No impact from pressure changes,
- Easy installation using a pipe wrench • Removes the minimum amount of water required to prevent damage caused by freezing.
