Abstract: 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).

Abstract: Network management bandwidth is estimated. Customer requirements are mapped to device type categories. Bandwidth requirements for each device type category are calculated using unit fault requirements and unit performance requirements that are derived from fault attributes and performance attributes, respectively. Overhead bandwidth, polling equipment bandwidth, and web portal bandwidth are also calculated using the customer requirements. A network management bandwidth requirement is calculated using the device type bandwidth requirements, the overhead bandwidth requirement, the polling equipment bandwidth, and the web portal bandwidth requirement. The network management bandwidth requirement is used to select a suitable communications link to monitor and manage a customer's network.
