Heavy-Duty Brass Copper Quick-Coupling Valves - Reliable China Suppliers & Factory for Irrigation Solutions
PRODUCT DESCRIPTION
RAIN LING Cooper Quick-Coupling Valves Series is engineered for professionals who demand strength, reliability, and precision in every irrigation component. Constructed from solid brass, these valves provide durable, corrosion-resistant performance that withstands years of use in outdoor and underground environments.
Unlike plastic couplers, cooper quick-coupling valves deliver superior pressure resistance and long-term mechanical stability, making them ideal for high-demand applications such as golf course irrigation, sports fields, and landscape maintenance.
Each valve includes a secure two-piece configuration — a valve body and a key rod — ensuring controlled water access and safe operation. The valve cannot be opened without its corresponding key, preventing water loss and unauthorized use.
Available in both 3/4" (DN20) and 1" (DN25) sizes, these quick couplers are compatible with most major irrigation systems and accessories, providing a universal and efficient water access point for service, cleaning, or hand watering.
With working pressure rated up to 8 bar, the Cooper Quick-Coupling Valve Series combines industrial-grade durability with smooth operation, ensuring consistent performance in demanding irrigation environments.
Solid Brass Construction
Corrosion-resistant, solid brass body for underground and outdoor applications.
Two-Piece Security
Prevents unauthorized water access and tampering without the key rod.
High-Pressure Rated
Handles working pressure up to 8 bar for demanding commercial irrigation.
