A multi-way valve suitable for use with large particle abrasive slurries. The valve has a housing and a seat piece affixed to the housing that defines a chamber. The seat piece has a conical valve seat. A rotor defines a conical base end that is received in the conical valve seat. A spring member biases the conical base end of the rotor against the conical valve seat to center the rotor and to allow the rotor to glide over large particles and for compensating for wear of the rotor over the lifetime of said rotor. The rotor has a first fluid path that is over a top of the rotor and a second fluid path that is through a bridge passageway in the rotor, thereby pressure balancing said rotor. The first fluid path provides continual flushing of particles from the chamber.
