    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.

    DETAIL DISPLAY

    FREQUENTLY ASKED QUESTIONS

    What materials are RAIN LING Quick-Coupling Valves made of?
    RAIN LING Quick-Coupling Valves are constructed from solid brass (copper alloy). This premium material ensures long-lasting, corrosion-resistant performance that easily withstands harsh outdoor and underground environment conditions.
    What connection sizes are available for this series?
    The series is available in two standard sizes: 3/4" (DN20) for Model RL-VQ75S and 1" (DN25) for Model RL-VQ100S, making them compatible with most major commercial and residential irrigation systems.
    How does the two-piece configuration prevent unauthorized water use?
    Each unit consists of a separate valve body and a matching key rod. Water only flows when the key rod is inserted and engaged into the valve body. Without the key, the valve remains closed, effectively preventing water theft and vandalism.
    What is the working pressure rating for these brass valves?
    The valves are rated for a working pressure of 2 to 8 bar, which makes them highly suitable for high-demand irrigation setups such as golf courses, athletic fields, and municipal landscaping.
    Do RAIN LING Quick-Coupling Valves come with a warranty?
    Yes, both models (RL-VQ75S and RL-VQ100S) come with a comprehensive 3-year warranty covering manufacturing defects and material reliability.
