PRODUCT DESCRIPTION
RAIN LING Plastic Quick-Coupling Valves Series provides a convenient and efficient way to draw water directly from your irrigation line. Designed for professional and residential irrigation systems alike, these valves offer instant access to water for hand watering, testing, or maintenance—without the need to cut or reconfigure the system.
Each valve features a spring-loaded internal seal that opens only when the key or coupler rod is inserted, ensuring safe and leak-free operation. The body is constructed from high-strength PP plastic, resistant to UV radiation, corrosion, and mechanical stress, guaranteeing reliable performance even in harsh outdoor environments.
Four-Piece Sets (RL-VQ75 / RL-VQ100)
- Includes valve body, key rod, elbow, and connector, providing a complete quick-access solution.
- Key-rod interlock mechanism prevents accidental water release.
- Ideal for turf and golf course maintenance, landscape irrigation, or cleaning equipment.
- Available in 3/4" (DN20) and 1" (DN25) connection sizes.
Three-Piece Sets (RL-VQ75A / RL-VQ100A)
- Includes valve body, water key, and fixing plate, ensuring simple installation and compact structure.
- Designed for smaller irrigation zones or garden applications.
- Valve remains securely closed until the key is inserted.
- Durable plastic ensures stability under pressure and easy replacement.
With working pressure from 2 to 8 kg (≈29–116 psi), this series ensures stable flow control and quick connection in all types of irrigation environments. Whether used in parks, golf courses, or home gardens, Rain Ling’s Quick-Coupling Valves combine efficiency, safety, and reliability—an essential component for any modern irrigation network.

Q
What materials are used to construct the valve body?
The body is constructed from high-strength PP plastic. This material is specifically selected for its durability, as well as its resistance to UV radiation, corrosion, and mechanical stress in harsh outdoor environments.
Q
What is the difference between the Three-Piece and Four-Piece sets?
The Four-Piece Set (RL-VQ75 / RL-VQ100) includes a valve body, key rod, elbow, and connector for comprehensive configurations. The Three-Piece Set (RL-VQ75A / RL-VQ100A) includes a valve body, water key, and a fixing plate, designed for simpler and more compact installations.
Q
What connection sizes are available?
Both the Three-Piece and Four-Piece valve sets are available in two standard connection sizes: 3/4" (DN20) and 1" (DN25).
Q
How does the valve prevent accidental water leakage?
Each valve features a spring-loaded internal seal and a key-rod interlock mechanism. The seal only opens when the corresponding key or coupler rod is fully inserted, preventing accidental water release and ensuring leak-free performance.
Q
Does the Quick-Coupling Valve series come with a warranty?
Yes, all models in this series (RL-VQ75, RL-VQ100, RL-VQ75A, and RL-VQ100A) come with a 3-year warranty covering material quality and manufacturing defects.
