PURPOSE: Provided is a valve structure for a double-acting jacquard weaving machine which principally excludes the miss-operation thereof due to the remnant magnetic field, and correctly makes the valve operation, thereby lowering the defective proportion and speeding the weaving operation. CONSTITUTION: A valve structure for a multiple driving jacquard weaving machine comprises: upper and lower cords(6a); two hooks(5) connected to the upper cord; a knife(8) for elevating the hooks; latches(3) coupled to the hooks; and a solenoid(1) for attracting or repelling the latches. Grooves are formed at the front end portions of the latches, and permanent magnets(2) are provided at the grooves. The solenoid has no core. The solenoid only has a plastic bobbin(1a) with a through-hole, and a coil(1b) wound on the bobbin. The permanent magnets of the latches are inserted into or detached from the end portions of the through-hole.
