Directional Control Valve Locking Device

A locking device for securely locking a directional control valve in a desired operating position comprising:

• an adjustable locking plate comprising a planar plate member having a stem slot therein for receiving the existing valve stem and mounting the adjustable locking plate to said valve, a plurality of locking holes therein, and a plurality of ball detent holes and a travel stop hole to receive the corresponding components on the valve and be operably connected thereto;
• said adjustable locking plate moving coaxially with the stem of the valve to various operating positions;
• a fixed locking bracket comprising a mounting portion and a locking portion, said mounting portion having at least two mounting holes therein for receiving the existing valve bolts such that the fixed locking bracket is mounted to the valve, said locking portion having a plurality of locking holes, said locking holes of adjustable locking plate adapted to be aligned with said locking holes of the fixed locking bracket at the various operating positions so that a locking means can be passed therethrough, securely locking the valve in the desired operating position;

A locking device for securely locking a directional control valve in a desired operating position comprising:

• an adjustable locking plate comprising a planar plate member having a stem slot therein for receiving the existing valve stem and mounting the adjustable locking plate to said valve, at least three locking holes therein, at least 3 ball detent holes and a travel stop hole to receive the corresponding components on the valve and be operably connected thereto;
• said adjustable locking plate moving coaxially with the stem of the valve to a plurality of operating positions;
• a fixed locking bracket comprising a mounting portion and a locking portion, said mounting portion having at least two mounting holes therein for receiving the existing valve bolts such that the fixed locking bracket is mounted to the valve, said locking portion having at least three locking holes, said locking holes of adjustable locking plate adapted to be aligned with said locking holes of the fixed locking bracket at the various operating positions so that a locking means can be passed therethrough, securely locking the valve in the desired operating position, thereby preventing the unauthorized, inadvertent or otherwise undesired manipulation of the valve from the desired operating position.
