As the plug is rotated from its closed position on the cooperating seat by the rotation of a shaft fixed to one of the plug supports the wing member lies in the fluid flowing through the valve. This fluid flow causes the wing member to exert a rotative force on the shaft in the direction to move the plug in its valveopening direction.
