The invention relates to a device () for cooling heat-sensitive control members () of a pneumatic or electropneumatic valve (), comprising a containment casing () designed to contain said control members (): a fresh air inlet () in said containment casing (); an air outlet () of said containment casing, provided with a ventilation air tube () that comprises: an air acceleration column () which puts into fluidic communication said containment casing () and the air outlet (); a primary supply () for supplying the acceleration column () with primary air; a secondary supply () for supplying the acceleration column () with secondary air, provided in said containment casing () such that the primary air can drive and accelerate the secondary air in the direction of the air outlet so as to produce forced air ventilation in said containment casing () between the air inlet () and the air outlet ().

Device for cooling heat-sensitive control members of a pneumatic or electropneumatic valve, and valve equipped with such a cooling device

A fluid flow control valve includes a valve body, a closing member arranged in the valve body and configured so that it can have at least one first position, called the open position, in which it allows the flow of fluid to flow freely in the valve body, and at least one second position, called the closed position, in which it prevents the fluid flow from flowing in the valve body between the fluid inlet and the fluid outlet, an electric actuator of the closing member that is suitable for being able to control the position of the closing member in the valve body, characterized in that the electric actuator is arranged in the valve body so that it can be cooled by the flow of fluid flowing in the valve body.
