Design & Structure:

• Body constructed from Polypropylene Random Copolymer (PPR), providing lightweight yet robust performance.

• Features an internal shut-off mechanism (typically a stem and sealing element) operated via a manual handwheel or lever.

• Ends are socket-type for fusion welding to PPR pipes, ensuring permanent, leak-free joints.

Material Properties:

• Made from PPR Type 3 (PP-R80/PP-R100) as per ISO 15874 standards.

• Excellent resistance to scaling, corrosion, and most chemicals.

• Non-toxic and physiologically safe, suitable for potable water applications.

• Thermal stability for both hot and cold water supply systems.

Performance Characteristics:

• Standards: Designed and tested according to ISO 15874 (Plastic piping systems for hot and cold water installations – Polypropylene).

• Operating Pressure: Typically rated up to PN16, depending on dimension and application.

• Temperature Range: Continuous operation from 0 °C up to 70 °C (short peaks up to 90 °C).

• Durability: Service life exceeding 50 years under normal operating conditions.

• Leak Tightness: Ensures bubble-tight shutoff when closed, preventing backflow or leakage.

Applications:

• Domestic and commercial hot/cold water networks.

• Heating and chilled water systems.

• Industrial fluid transport requiring safe and hygienic shutoff.

• Plumbing systems requiring section isolation for maintenance.

Installation:

• Connected to pipes by socket fusion welding or electrofusion.

• Designed for compatibility with other ISO 15874 PPR fittings.

• Maintenance-friendly—valve can be closed for repairs without draining the full pipeline.
