Abstract
The present invention relates to an electrically controlled leakproof valve having a fluid feed channel and at least one channel for delivering said fluid, rotary displacement of a distributor plug in said valve being under the control of an actuator. The actuator comprises an axially pierced rotor through which the fluid from the feed channel flows without headloss, the actuator being connected to the valve body in leakproof manner without using dynamic sealing devices. The present leakproof valve is particularly suitable for use in corrosive environments, and in particular under cryogenic conditions.
