    Condition: New
    Direct replacement for Sealco 110139 relay valves
    Ratio Feature
    Do not use this valve on converter dollies, trailer turntable axles or lift axles
    4 Delivery ports
    Auxiliary supply port = 3/8" pipe thread
    Control port size = 3/8" pipe thread

    Delivery port size = 3/8" pipe thread
    Nominal crack pressure = 4.5 psi

    The Ratio Feature is considered a benefit in hard stop situations and refers to the relationship between the control air pressure to the valve and the delivered air pressure from the valve to the service brake chambers. During normal stopping, a 1:1 ratio exists between the control and delivered air pressures. In a hard stop, the ratio momentarily changes to 1:1.5 until valve lap-off occurs and the ratio is restored. This change takes place in less than 1/100th of a second.
