Abstract

Refinements introduced into a sliding or slide gate valve to control the flow of a molten metal, in which the valve slide plate is connected for position control to a hydraulic or pneumatic actuator unit, characterized in that the actuator unit comprises a pair of pistons arranged in-line, and WHY the actuator unit has one end thereof connected to the slide plate and the other end of the actuator unit is immovably arranged, the first piston being, in normal use, idle and serving to define a reference position, and the second piston being operable to move the slide plate going back and forth relative to the reference position, to open and close the valve.
