Bermad - Model K10 - Kinetic Air Valve

BERMAD K10 is a high quality kinetic air valve for a variety of irrigation networks and operating conditions. It evacuates air during pipeline filling and enables large volume air intake in the event of network draining. With its advanced aerodynamic design and kinetic orifice, this valve provides excellent protection against vacuum formation, With improved sealing under low-pressure conditions.

Features & Benefits

• Straight flow body with large diameter orifice – High flow rates
• Aerodynamic full-body kinetic shield – Prevents premature closing without disturbing air intake or discharge.
• Dynamic sealing – Prevents leakage during operation even under low pressure conditions (0.1 bar).
• The boss on the base can be tapped with a thread for pressure gauge connection, check point or test drain for air valve function.
• Compact, simple and reliable structure whose parts are fully corrosion, chemical and fertilizer resistant – Lower maintenance and increased life span
• Factory approval and Quality Control – Performance and specification tested and measured with specialized test bench, including vacuum pressure conditions.

Typical Applications

• Main Irrigation Networks – Air relief and vacuum prevention downstream of pumps, along supply lines and at elevations in main irrigation networks.
• Irrigation Control Heads – Air relief and vacuum prevention at filtration and fertilization stations.
• Infield Systems – Prevention of vacuum formation
• Landscape Irrigation – Prevention of vacuum formation
