They are used for preventing the lines, which are closed by locking method used for closing the lines controlled by the valves, from opening by unauthorized staff. It is a locking system covering the valve’s handle’s housing and preventing the ball from turning in which the lock is screwed to thread of turning spindle of the ball of the valve through its key after the handle of the ball valve is removed. The valve lock body is made of a single part. Handle of the ball valve is unscrewed and removed. Channel existing on the lock’s body is run through the handle bearing of the valve. Also, opening-closing spindle of the valve is run through the channel on the fixing washer and then, connected to the connection bolt. The connection bolt may be manufactured in various sizes according to the thread of the spindle of the valve. Thus, the lock can be used for different make valves. Thus, the lock embraces the opening-closing spindle of the valve and is mounted to the valve’s body. As a result, the valve is locked because it is prevented from moving. The valve locks are manufactured separately for the ball valves with various diameters used in practice. The lock is made of steel completely. This increases resistance of the lock against external impacts and challenges. We supply most of our products to natural gas distribution companies.
