Dig Corporation Polyethylene w/ Check Valve Dripline 17 mm x 500' 1 gph 18" Space Brown | A1-518P-CV

Key Features

• Inline emitter check valves prevent drainage from the dripline when water pressure drops below 2.5 psi, protecting the emitters against the siphoning of small sediment and soil particles into the drip emitter
• Two outlets per emitter, If one outlet becomes blocked, a second outlet on the opposing side of the dripline provides redundancy to the dripline performance
• Pressure compensating feature provides flow uniformity regardless of operating pressure and variation along the line
• Drip emitter and diaphragm are self-contained units molded to the interior wall of the tubing
• Flow path design supports superior clogging-resistance
• Turbulent flow through large labyrinth water passages leads water into the flow control chamber where a sensitive floating silicon diaphragm regulates and maintains a constant flow rate at variable inlet pressures
• Dripline includes one inlet and two outlets per each emitter
• Intake inlet has a number of raised grooves that act as a secondary filter
• Check valve and dual, oppositely oriented directional outlets act as a physical barrier to root and debris intrusion
• Resistant to chemicals and fertilizers commonly used in landscape applications
