Combination Air Valve

• Straight flow body with nominal (equal) inlet and outlet size: Higher than usual flow rates.
• Dynamic Sealing: Prevents leakage under low pressure conditions (1.5 psi; 0.1 bar).
• Threaded Side outlet (2"; DN50) for connection of Surge Protection (SP) or Inflow prevention (IP) devices.
• Cֺompact and simple structure, whose internal parts are fully corrosion, chemical and fertilizer resistant: Lower maintenance and increased life span.
• Field proven designed for use in irrigation applications with water quality such as river water, channel water, dam water or treated effluent with high reliability.
• Certified to functional standards: SAI AS4956 (Australia).
• Factory approval and Quality Control: Performance and specification tested and measured with specialized test bench, including vacuum pressure conditions.

การใช้งานทั่วไป

• Main irrigation networks: Protection against air accumulation and vacuum formation downstream of pumps, along supply lines and at elevations in main irrigation networks.
• Irrigation and landscape control heads: Protection against air accumulation and vacuum formation at filtration and fertilization stations and downstream of main control valves.
• Infield Systems: Protection against air accumulation and vacuum formation in proximity to water meters and automatic regulators.
