Pro-lock, Valve lockout is a Universal system, that can complement or even replace, high priced security seals, padlocks and chains. Ideal for the isolation of most types of valves, industrial machinery, and many other items, Pro-lock is molded from Atofina PPC 9760, an impact copolymer polypropylene. It is UV stabilized and all internal parts are manufactured from stainless steel. Pro-lock  is used in conjunction with PVC coated, multi stranded, galvanised, steel wire, supplied, either cut to the required length, or left on the roll as required.

 Pro-Lock Cable Lockout System


Thread the cable through the valve handle. Pro-lock is designed to be locked on to this cable using the special tool provided. For added security, pro-lock can be used in conjunction with padlocks or
security seals

Gate Valve Isolation

Originally designed as a cost effective solution, to lock any type of valve in aggressive offshore environments, Pro-lock is tough and extremely versatile, Function testing has been carried out between -55degC and +55degC with no noticeable reduction in performance. Pro-lock offers a reliable, alternative to expensive or more difficult to use lockout products such as padlocks, chains and security seals.

Each Pro-lock is supplied with 1.5 meters of multi-stranded galvanized steel wire (optimum length for valve locking applications). This is PVC coated for added weather protection and increased visibility. This wire may be supplied cut to lengths of 1.5M, and looped at one end for added versatility, or left on roll  (50M) as required. (Note: Heavy duty Angular type cutters are required for cutting the wire.) If the cable is purchased on the roll, Aluminium or Copper ferrules can be supplied to fashion loops on customised lengths. These can be either be tapped in position using a small hammer or pressed into position using various means. (Note2: The loop is useful, but not essential).

How Pro-lock Works

No threading of wire is necessary. The wire is slotted in from the side. The top section of the lock is hand tightened to secure the cable on to the valve. The Pro-lock is then slid along to the optimum position, much like the knot of a neck tie, then locked onto the cable using the Pro-lock Operating Tool.

Ball valve locking pins can be supplied to prevent movement and to enable the secure locking of those ball valves, that don't have a drilled valve handle through which to secure the cable. See pic opposite.

 Wire Introduced from sides (No Threading)
