The Add-A-Stack® 4020 valve is a multifunction valve originally designed to control cylinders and motors on truck applications. The enclosure is a cost effective solution to protect the valve from typical corrosion problems of exposed valves. A simple rubber latched cover employs a gasketless weather resistant seal design that stops harmful salt spray.
