Line End Valve – Automatic Flush Valve
Automatic flush/drain valve for the end of drip lines: flushes dirt out when the system starts up and closes automatically; connection optionally male thread, lock type or barbed.
Description
The automatic line flush valve is installed at the end of the drip line. When the system is filled, it flushes deposits and dirt out of the line and closes automatically once operating pressure is reached (auto-off); when the system is shut down, it opens again and drains the line. This reduces dripper clogging and simplifies system maintenance without manually opening the line ends. Made of impact-resistant polypropylene.
