An electric valve for pipe organs is adapted to be mounted within an air chest and is provided with a valve member on an armature adapted to cooperate with a valve seat surrounding an air passage in the chest leading to a pipe. The valve member is comprised of a base member, a resilient member and a valve seat engaging member adhesively secured together with sufficient slack in the valve seat engaging member or the base member and air passages which permit direct contact of the pressurized air within the air chest with the valve seal engaging member to allow bounce of the armature while maintaining the valve seat engaging member in engagement with the valve seat. The armature extends through and is pivoted on a bracket by means of two ball bearings press fitted into sockets on opposite sides of the armature. The sides of the bracket are then pressed toward each other against the ball bearings which will then be pressed into the bracket to form complimentary sockets.
An electric valve for pipe organs comprising a bracket adapted to be mounted within an air chest of an organ, a coil fixedly mounted on said bracket and an armature having a valve member thereon pivotally mounted on said bracket and resilient means connected between said bracket and said armature for normally biasing said valve member in the closing direction, said valve member being comprised of a base member secured to said armature, a resilient member connected to said base member and a valve seat engaging member secured to one of said base and resilient members with at least one of said valve engaging member and base member being flexible and at least partially unsecured relative to said resilient member to compensate for armature bouncing while maintaining said valve engaging member in sealing engagement with a valve seat on said chest.
