ABSTRACT:
A novel gate for use in a gate valve is provided with a cylindrical port which extends from the gate's upstream face to a downstream face. Sand grooves are provided on each face and passages extending in a radial direction from the port's cylindrical wall to the grooves are also provided. The passages are thus aligned with their longitudinal axes being generally perpendicular to the direction of fluid flow which enhances flushing of particles such as sand or scale from the grooves. A novel shell core and core box for making same are also disclosed.
