ABSTRACT:
A safety device especially for use with a relief valve having a disk which is controlled by a pilot valve. The safety device is connected between the pilot valve and the relief valve and provides means for closing the relief valve if the pilot valve should fail. The safety device includes a body mounted between the pilot valve and the disk of the relief valve. A spring biased cage mounted inside the body is kept in a locked position away from the disk until the pilot valve fails. Upon failure of the pilot valve the cage is unlocked and the spring presses the cage against the disk to close the relief valve.
