Abstract
A traction valve is provided for use in combination with a relay valve. The traction valve includes a body configured for connection to a housing of the relay valve and defining inlet, outlet and traction supply ports. A first fluid control valve used for traction control is supported on the body and includes a valve member that alternately permits and prevents fluid communication between the traction supply and outlet ports in the body. The body and the first fluid control valve are configured to receive any of a plurality of interchangeable second fluid control valves between the inlet port in the body and the first fluid control valve. Each of the plurality of interchangeable second fluid control valves is configured to perform a different function such that the traction valve assumes different configurations upon assembly of the various second fluid control valves with the body and the first fluid control valve.
