Pressure Control Bubbler - 1.9l/min product_valve box lids - 150mm lid protecting pumps from back-spin andHunter pressure compensating bubbler nozzles deliver a controlled, low velocity flow of water directly to the root zone of trees, shrubs and raised planters, eliminating the soil erosion and water waste associated with conventional flood bubblers at variable pressures. The pressure compensating diaphragm maintains a consistent output from 1. 4 to 4. 1 bar, ensuring each tree or shrub receives the same volume regardless of its position on the zone.
