Maxiflame LK 556 G1 antifreeze safety valve – for heat pumps
The LK 556 AntiFreeze is a safety valve designed to protect heating systems from the risk of frost, particularly those with air/water heat pumps or external circuits.
The valve automatically intervenes when the fluid temperature drops below +3°C , draining water from the system to prevent damage to pipes and components. Operation is completely automatic and maintenance-free , and does not require resetting after intervention: the system can simply be refilled once circulation is restored.
The G1” model (male thread) is ideal for installations on medium flow hydronic circuits, guaranteeing safety and reliability even in critical climatic conditions.
Main technical features
- Connections: G 1” male
- Operating temperature: +3°C
- Max pressure: 6 bar
- Operating temperature: 0°C ÷ 75°C
- Body material: CW617N brass
- Gaskets: EPDM
- Automatic operation without power supply
Strengths
- Effective protection against frost
- Automatic intervention without electricity
- No maintenance required
- Simple system restoration
- Insulation available as an accessory for greater efficiency
