A valve member cooling arrangement for a valve having at least one housing with sets of working fluid inlet/outlet ports and coolant supply/return ports. A valve member movably disposed within a valve chamber has a valve head configured to control flow between the working fluid ports. The valve member has valve member inlet/outlet openings and defines an internal valve member cooling passage uniting the valve openings. At least one coolant sleeve is disposed about the valve member. The coolant sleeve(s) have inflow and outflow ports separated inflow from outflow by at least one seal. During static and dynamic positioning of the valve member, the valve member inlet(s) are in communication with inflow port(s) of the coolant sleeve, and the valve member outlet(s) are in communication with outflow port(s) of the coolant sleeve(s).
