Inta Zero Anti Freeze Valve

The patent pending Inta Zero anti freeze valve has been developed specifically for heat pump installations where protection against freezing temperatures is essential. Unlike conventional frost protection devices that rely on ambient air temperature, the Inta Zero valve reacts directly to the water temperature within the system. This allows the valve to provide fast, accurate protection while maintaining overall system efficiency.

The valve can be fully insulated in line with Building Regulations Part L requirements without affecting its performance. Independent testing has demonstrated that the valve continues to operate correctly even when installed within insulated external pipework. For guidance on insulation requirements, refer to the UK Government Building Regulations Part L.

Suitable for both domestic and commercial applications, the Inta Zero Anti Freeze Valve is available in a range of connection sizes to suit modern heat pump systems. By reacting directly to water temperature rather than ambient conditions, the valve provides reliable frost protection while helping to maintain overall system efficiency. Features such as double o-ring sealing, a protective debris ring, and reduced-friction internal components help ensure reliable long-term operation.

The Inta Zero range can also be paired with the Zero Guard protective cover and dedicated insulation accessories for enhanced installation protection.
