• 2 x Heat Pump Anti-freeze Valve 28mm x 28mm Compression
• 2 x Insulation jacket for Anti-Freeze Valve

Anti-freeze Valve 28mm connections

This anti-freeze valve designed and engineered to protect heat pump systems that are operating with water. Designed to discharge when the system water temperature drops to 3°C, preventing ice from forming in the heat pump circuit that could cause breakdown or costly damage to the system.

• Connections: 28mm Compression
• Max Inlet Pressure (static): 10 Bar
• Medium: Water
• Sensitivity: +/-1°C
• Opening Temperature: 3°C
• Closing Temperature: 4°C
• Working Temperature Range: 0 – 65°C
• Ambient Temperature Range: -30 – 60°C
• Kv: 64m³/h
• Max Discharge Flow Rate @ 3 Bar: 1.5 L/H

Insulating

The valves have been specifically designed to quickly and accurately react to the water temperature in the heat pump circuit and do not need the influence of the ambient temperature to operate.

Building regulations Part L states that all external fittings on an Air Source Heat Pump System must be fully insulated to reduce heat loss and maintain system efficiency. Anti-Freeze Valves will still maintain correct operation and discharge the water at the same temperature even when a system is correctly insulated.

If the valves are insulated, then due care must be taken to ensure that all external pipework and fittings are fully and appropriately insulated and sealed. Failure to do so could prevent the proper operation of the valve resulting in colder areas of a system being damaged by freezing. The Anti-vacuum valve must be kept clear at all times (inspected on annual service).
