Rex Air Valve Special

Rex Air Valve Special

This is a manually operated 3-way toggle air valve, commonly known as the 'Rex Air Valve Special', used in the air system of a rear discharge concrete mixer. Its primary function is to control the pressurization of the onboard water tank, allowing the operator to send air to the tank to dispense water for cleaning and slump adjustment. This valve is a critical component for daily operations and is a common replacement part due to wear and tear from constant use in harsh environments. The valve body is typically cast aluminum with brass fittings for the cylinder ports.
