A safety lock device for use in releasably locking the head of a butterfly valve. The two part safety lock device comprises first: a cross-sectionally U-shape elongated frame, having an anchoring part at one end and a lateral flange with a number of bores; the anchoring part releasably engages with the valve head for anchoring the U-frame to the valve head; the elongated channel is sized for full engagement by the valve handle; and second: a casing, with an inner passageway, sized for through engagement by the U-frame, and a lateral pocket extension with a number of bores, for engagement by the lateral flange. The casing is characterized by a wedge part, integrally depending therefrom and sized for engagement between the diverging distal end portions of the valve handle and lever. Padlocks releasably interlock the U-frame to the casing by engaging selected pairs of flange bores and pocket bores, thereby concurrently locking the valve lever in its divergent relation to the valve handle.
