Inta Zero Anti-Freeze Valve 1″ Male x 1″ Female Swivel – ZERO1SW

The Inta Zero Anti-Freeze Valve (ZERO1SW) is a high-quality, innovative solution designed to protect heat pump systems from freezing conditions. This valve features a 1″ male x 1″ female swivel connection, making it versatile and easy to install in a variety of setups.

Key Features:

• Automatic Temperature Sensing: Unlike traditional valves, the Inta Zero does not rely on ambient temperature. It directly monitors water temperature within the heat pump circuit, ensuring precise and timely operation.
• Effective Insulation Compatibility: The valve maintains full functionality even when insulated, conforming to Part L of building regulations, which requires all external fittings on Air Source Heat Pump Systems to be insulated to prevent heat loss.
• Safety Mechanisms: Equipped with a vacuum breaker and safety double o-rings, the valve ensures reliable performance while preventing system contamination from dirt and debris.
• Durability: Constructed from durable materials such as stainless steel and UNI EN 12165 CW617N brass, the valve is built to withstand harsh conditions. Internal seals are made of EPDM PEROX, ensuring longevity and resistance to wear.

Technical Specifications:

• Max Inlet Pressure: 10 Bar
• Opening Temperature: 3°C
• Closing Temperature: 4°C
• Working Temperature Range: 0 to 80°C
• Ambient Temperature Range: -30 to 60°C
• Max Discharge Flow Rate: 1.5 L/H at 3 Bar

Additional Information: The valve’s unique design includes a chamfered edge to prevent the formation and freezing of water droplets. For optimal performance, ensure that all external pipework and fittings are adequately insulated, and consider using the ZEROGUARD anti-vacuum cover for added protection.

This advanced anti-freeze valve is ideal for maintaining system efficiency and preventing freeze damage, making it an essential component for modern heat pump systems.
