Product Details:

    • Anti-vacuum device ideal for purging air from hot and cold water distribution systems and glycol chillers
    • Allows separation & dispersal of air while the fluid is circulating in the system
    • High-temperature-resistant polyethylene float to actuate the valve plug, which further prevents water from escaping the system
    • Automatic air vent with silicone rubber seal
    • Resistant to impurity contamination since the maximum float line of water always remains lower than the valve seal
    • Vent Height: 3-1/8 inches
