Designed to prevent the back-siphonage of contaminated water into the potable water supply. Features a lightweight, durable "disc float" suitable for temperatures up to 180 DEG F (82 DEG C) which closes the atmospheric vent to prevent spilling under all rates of flow. Upon downstream demand, the vent disc assembly rises, sealing the atmospheric vent, allowing water to flow. A loss of supply pressure or the creation of a negative supply pressure causes the vent disc assembly to drop, opening the atmospheric vent and closing the supply side orifice. This prevents backflow by allowing atmospheric pressure to satisfy a vacuum condition on the supply side of the valve. Recommended for low flow installations such as laboratory equipment which use small amounts of water. Contains a durable silicone disc which has high heat and water hammer shock-resistance and ensures tight seating with the lightest of seating contacts.
