Two-ball air valves
APPLICATION
Most often, in practice, the place of installation of air valves with large and small openings coincides, so, naturally, the design of an air valve with two balls was performed, which executes the functions of an air valve with both large and small openings.
Two-ball air valves remove air from the pipeline before commissioning, remove air that is released from the water during operation, and also prevent the occurrence of underpressure when emptying the pipeline or a breakdown in the pipeline system.
