By pushing or pulling the handle, the operator releases air from the suspension air bags to lower the trailer deck—useful when loading/unloading or to prevent trailer walk at a dock. Built with an anodized aluminum body and stainless steel shaft, it resists corrosion and operates in extreme temperatures. You would replace this valve if your existing dump valve is stuck, leaking, or no longer holding air.
