Bubbler Type Check Valve, High Capacity, 28/15, 150mm OAH, each

Bubbler Type Check Valve, High Capacity, 28/15, 150mm OAH. High capacity check valve bubbler keeps oil and air from being drawn into a reaction system when negative pressure is developed. Bubbler has two 1/2" Swagelock type fittings on top permitting one side to be connected to the nitrogen source and one side to the reaction system. The bubbler is filled with oil (mineral or silicone) to a level slightly above the top socket joint. Under negative pressure, the float is drawn up to seal the outlet and prevent back flow. When exposed to positive pressure, the float is pushed down opening the seal between the spherical ball float and socket joint providing for a high capacity outlet. Made in the United States.
