Abstract
The present invention relates to a subsea control valve () for controlling the supply of hydraulic fluid to a subsea fluid-actuated device (). The valve comprises a housing () with an input fluid line bore () connectable to a input fluid system (), a return fluid line bore () connectable to a return fluid system () and an actuator fluid line bore () connectable to the fluid-actuated device (). A ball valve member () with a through bore () is pivotably connected within the housing () between the input fluid line bore (), the return fluid line bore () and the actuator fluid line bore (), the ball valve member () having a first and a second position. The actuator fluid line bore () and the return fluid line bore () are connected to each other via the through bore () when the ball valve member () is in its first position, thereby allowing fluid to be returned from the fluid-actuated device () to the return fluid system (). The input fluid line bore () and the actuator fluid line bore () are connected to each other via the through bore () when the ball valve member () is in its second position, thereby allowing fluid to flow from the input fluid system () to the fluid-actuated device ().
