Combines the best of Techline and adds a Check Valve (CV). The most important breakthrough in low-volume irrigation since the introduction of drip.

Techline CV is the next generation of dripperline in the Techline family, and the the most sophisticated dripperline in the world. Techline CV incorporates the best features of Techline and adds a Check Valve feature. Techline CV's Check Valve feature is the most important breakthrough in low volume technology since the introduction of dripperline, because water does not drain out of the dripperline after zone shut-down.
Applications:
At-grade windows
Subsurface or on-surface installations
Slopes
Curved, angular or narrow planting areas
High traffic/high liability areas
Areas subject to vandalism
High wind areas
Turf, shrubs, trees, flowers
Where sprinklers could cause a tripping hazard
Sports turf
Tennis courts
Specifications:
Broadest choice of dripper flow rates: 0.26, 0.4, 0.6 and 0.9 GPH
Dripper spacings: 12", 18" and 24"
Pressure compensation range: 14.7 to 70 psi (stainless steel clamps recommended above 50 psi)
Maximum system pressure: 50 psi
Diameter: 0.66" OD; 0.56" ID
100', 250' coil lengths
Recommended filtration: 120 mesh
Features and Benefits:
Each Dripper has a 2 psi Check Valve
o All drippers turn on and off at the same time
o Minimizes water loss: Techline CV dripperline contains 1.3 gallons of water per every 100'. This water does not drain out and get wasted after zone shut-down.
o Holds back up to 4 1/2' of water
o No low drainage, great on slopes
o More precise watering
Built-In Physical Root Barrier - drippers are protected from root intrusion without chemical reliance
Pressure compensation - all drippers deliver equal flow
Unique flow path - Turbonet technology allows more control of water flow and less chance for clogging
Continuous self-flushing dripper design - flushes debris as it is detected - throughout operation, not just at the beginning or end of a cycle and ensures uninterrupted dripper operation
Extremely large filter area - provides uninterrupted water flow
Single hole dripper outlet from tubing
o Better protection against root intrusion
o Allows the dripperline to be used in subsurface applications without chemical protection
Easy to design in slope and berm applications - water does not drain out of low drippers
No air/vacuum relief valves required - installations are faster and less expensive
Techline compatible
Techfilter compatible - provides a limited lifetime warranty against root intrusion
Dark Brown Color - visually identifies Techline CV, better blending into surrounding colors of landscapes
