What is the purpose of quick coupling valve?

• A. To seal against leakage at high pressure
• B. Quick connects lines quickly and without tools or product loss
• C. To regulate pressure in a circuit
• D. To measure flow rate

Answer: (B)

Quick coupling valves provide a fast, tool-free way to access the irrigation main for maintenance, temporary lines, or testing. With a special key, you open the valve to connect a hose or portable line and close it to stop flow, all without tools and with minimal water loss. This makes switching lines or performing maintenance quick and clean, since the valve is sealed when not engaged. They aren’t meant to regulate pressure or measure flow—that’s handled by separate components—so the main purpose is simply to offer a rapid, controlled connection point that minimizes product loss.
