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
During the filling process of a pipeline, high air flow is forced out through the kinetic orifice of the air valve. Once water enters the valve’s chamber, the float buoyed upwards causes the kinetic orifice to close. The unique aerodynamic structure of the valve body and float ensures that the float cannot be closed before water reaches the valve.
During pressurized operation the kinetic orifice remains closed.
When a pipeline is drained, a negative differential pressure is created causing atmospheric air to push the float down. The kinetic orifice stays open and air enters the valve chamber, preventing vacuum formation in the pipe.
