A failsafe valve system configured to bring the valve to a predefined state (e.g., fully opened, fully closed) if the actuator fails (e.g., loss of power). The failsafe system of the present disclosure is energy efficient and reliable.

Failsafe actuated valve

A refuel adapter, which may, among other things, be suitable for aircraft refueling includes a casing and a butterfly valve disposed within an interior of the casing. The butterfly valve includes a body defining an opening and a disc rotatable within the body about an axis of rotation to selectively close the opening. The disc includes at least one opening therethrough, and a first flap and a second flap are each rotatably attached to the disc to selectively cover a portion of the at least one opening. The butterfly valve may be movable between (i) a static position in which the disc and the first and second flaps are in a closed position, (ii) a refuel position in which the disc may be in a closed position and the flaps are in an open position, and (iii) a defuel position in which the disc may be in an open position.
