Abstract
A control valve for regulating flow of fluids passing through the valve. The control valve includes a body with an inlet, an outlet and a passageway through which the fluid passes from the inlet to the outlet. The control valve also includes a displaceable column provided with an internal and concentric bolt, the displaceable column is actuated by an actuator, the actuator positioned in a chamber that is connected to the body, a valve closure attached to the displaceable column. The displaceable column moves between a most retracted position, in which the inlet is fluidically communicating with the outlet, and a most pulled out position, in which the valve closure sealingly blocks the passage of fluid through the control valve.
