Quick Coupling Valves (QCV)
Quick Coupling Valves, or Turf Valves, commonly known as QCVs are a tool used to tap into the mainline water pipe of your sprinkler system. They are installed at ground level on their own or in a valve box.
With an internal valve to avoid any leakage, simply activate the valve with the key and lock in place. The key has a 3/4" male thread where you can attach a sprinkler or hose. Remove the key to close off the valve and the access to water.
