The UV-Resistant PP Compression Union Valve is engineered to thrive in outdoor water systems where prolonged sunlight exposure threatens conventional plastic fittings. Built with UV-stabilized polypropylene (PP) and a three-layer construction, this valve combines compression-style convenience with long-term weather resistance, making it indispensable for above-ground installations. Unlike non-UV-treated valves that become brittle and crack after 1–2 years of sun exposure, this model retains structural integrity for at least 10 years under ultraviolet radiation exceeding 700 kly (kilolangleys)—equivalent to decades of tropical sunlight . Its compression design enables tool-free installation, while the UV protection ensures reliability in gardens, rooftops, and bridge drainage systems.
The valve’s outer layer incorporates UV inhibitors that absorb and dissipate harmful solar radiation, preventing photo-oxidation of the polypropylene matrix. This treatment meets EN 13476-2 Type A standards for UV resistance, ensuring the valve maintains flexibility and impact strength even after prolonged outdoor exposure. The middle layer features structured PP for enhanced ring stiffness, while the smooth inner layer minimizes flow resistance .
The compression union design uses a brass compression nut and EPDM gasket to create a watertight seal without welding or threading. This allows for quick installation and disassembly, with compatibility for pipe sizes from 20mm to 63mm OD. The mechanism maintains a secure connection under pressure up to 6 kg/cm², suitable for most residential and light commercial water systems.
Formulated to resist aggressive substances in water and soil (pH 2–12), the valve handles chlorinated water, rainwater, and mild agricultural chemicals without degradation. It operates reliably in temperatures ranging from -10°C to 80°C, making it suitable for both cold climates and sun-heated outdoor lines .
This valve excels in outdoor and exposed water systems:
Residential Gardens: Controls irrigation lines, sprinkler systems, and rainwater harvesting setups without sun-induced degradation.
Bridge and Overpass Drainage: Manages runoff in infrastructure applications where direct sunlight exposure is constant .
Agricultural Fields: Regulates water flow in open-air irrigation systems, resisting damage from sunlight and fertilizer exposure.
Rooftop Water Systems: Manages overflow and drainage in green roofs and rooftop gardens, withstanding daily UV exposure.
UV radiation breaks down the molecular structure of non-stabilized PP, causing brittleness and cracking. The valve’s UV-stabilized material prevents this degradation, extending service life from 1–2 years to 10+ years in outdoor environments .
Yes. The brass compression nut and EPDM gasket retain their sealing properties after multiple disconnections, making the valve ideal for temporary installations or systems requiring frequent maintenance.
Yes. The UV-stabilized PP and EPDM gaskets meet international standards for potable water contact, ensuring no harmful leaching or taste/odor contamination.
The valve is rated for continuous operating pressures up to 6 kg/cm², which is sufficient for most residential outdoor water systems, including irrigation and rainwater harvesting setups.
