    For maximum protection from system contamination, these valves have two integral check valves with a vent between them. If the primary check valve fails to close when flow stops or reverses, overflow is discharged through the vent and the secondary check valve prevents backflow.
    Chrome-Plated Brass Body—Chrome-plated brass valve is more corrosion resistant than plain brass valves.
    Unthreaded—Valve with an unthreaded vent is commonly used on laboratory faucets and other applications with intermittent flow. It discharges overflow directly and should not be installed in areas where spillage could cause water damage.
