ANTIFREEZE VALVE LK 556 ANTIFREEZE VALVE G32UK
Product code
3946721
LK 556 AntiFreeze protects your heating system, typically an air-to-water heat pump, by draining the system if the heating water temperature drops below +3 °C, thereby preventing the risk of freezing.
If the valve opens at too low a temperature and drains the system, the valve does not need to be reset; the system can be refilled immediately once normal circulation in the heating system is restored.
An insulation accessory is available for maximum energy savings; see spare parts and accessories.
