Product Description Line Flushing Valve 1/2″ Optimize System Performance. Helps reduce maintenance and increase dripper line performance. Applications; Drip irrigation systems Clean or dirty water Specifications; Flushing water volume: approx. 1 gallon per cycle Maximum zone flow rate per Flush Valve: 15 GPM As irrigation starts, valve flushes out dirt particles Minimum pressure required: 1.5 psi in the open position. Maximum pressure: 57 psi Features/Benefits; Flushing reduces sediment build-up Automatic cleaning operation at start of each irrigation cycle Unique design reacts to flow, not pressure, allowing operation even at full line pressure Can be disassembled to allow for winterization “blowout” Normally open – full opening at the beginning of irrigation cycle. Flushing- while pressure builds up in lateral, water velocity flushes the debris out through opening. Closing – small quantity of water flows into upper chamber, causing diaphragm to seal openings. It remains sealed until irrigation cycle ends, then the diaphragm gradually opens again. **You will need a Female Compression Tee 16mm-1/2″-16mm per valve** Click for Product Brochure
