Low temperature antifreeze compression valve (-15°) for PE / PPR tubes

The PP antifreeze ball valve is a state-of-the-art shut-off solution, specifically developed to meet the demands of environments subject to extreme climatic conditions. Thanks to its innovative design, it offers increased resistance to repeated freezing and defrosting cycles, guaranteeing continuity of service where standard valves might fail. This high-performance compression fitting enables easy, fast and secure connection of polyethylene (PE) and random polypropylene (PPR) pipes.

Exceptional thermal resistance: -15°C to +80°C

Designed for maximum thermal versatility, this valve withstands a wide temperature range from -15°C to +80°C. Its body and compression nuts are injected in high-grade polypropylene, treated against UV rays and frost, preventing premature structural degradation outdoors. This thermal robustness means that the device can be used both in geothermal installations and in water supply networks exposed to harsh winters.

Frost-proof design and multi-material sealing

The major innovation of this valve lies in its ability to drastically limit water stagnation between the sphere and the body, thus reducing the risk of breakage due to ice expansion. Watertightness and smooth operation are ensured by an assembly of premium components:

• Chrome-plated brass sphere housed in a PTFE shell and seats for minimum friction.
• Double O-ring seal in EPDM around the shaft for long-lasting tightness when handled.
• NBR O-ring specifically designed to seal around the tube.

PN 16 bar performance and versatile applications

With a pressure rating of PN 16 bar, this ball valve can handle highly stressed flows, including compressed air and wastewater. Its ergonomic, glass-filled polyamide (PA) handle ensures optimum mechanical strength and UV protection. It is ideal for securing watering or irrigation networks in mountainous areas, where night frosts are frequent and intense.

Simplified installation for PE and PPR networks

The compression connection system allows installation without the need for special tools, guaranteeing considerable time savings on construction or maintenance sites. Thanks to its brass shaft and inert structure, the valve is perfectly suited to geothermal and drinking water supply configurations. When you choose this model, you're opting for maximum safety and a reduction in maintenance operations related to frost damage to outdoor hydraulic infrastructures.
