Abstract
A purge drain valve including a spool spliced in a fluid line includes a control valve and an actuator coupled to the control valve for regulating fluid flow. During a washing operation, fluid flows between a supply end and a delivery end of the spool, and during a purging operation, the control valve diverts fluid entering the supply end from the delivery end towards a drain leg. A washing system includes a fluid supply coupled to an input of a wash delivery system and a delivery line coupled to an output of the wash delivery system. The purge drain may be spliced into the delivery line to permit fluid to reach a wash apparatus during a washing operation and to prevent fluid from reaching the wash apparatus during a purging operation. A rinse cycle sensor apparatus may be employed to indicate to an operator if a washing operation is complete based upon a conductivity of fluid exiting from a device being washed.
