uPVC Valves
The uPVC valves, models 95 (threaded) and 96 (solvent
welded directly to the pipe) are made for high-flow irrigation
plots and flood tables. The direct- attachment to the PVC
pipelines and the optional underground installation, save
cost of valve configurations and reduce head losses. Unique
diaphragm design generates surge- free closure even at
high velocities.
Unique hydrodynamic design allows exceptionally low
pressure losses at high flow rates, stable regulation from
maximal to near zero flows, surge-free closure and simple,
minimal maintenance.
Features and Benefits
• Structural simplicity
• Superb hydraulic performance
• Reliable control of corrosive liquids
• Light-weight, cost-saving
• Minimum maintenance - maximum dependability
