Pro-lock ball valve lockout
provides a secure method for isolating ball valves
and most other valve types.

- Gate Valve
- Butterfly Valve
- Needle Valve

Pro-lock ball valve lockouts secure the handles
of the valves and prevent them from being turn actuated, either
in the on or off position. Pro-lock valve lockouts are durable and
will not rust or corrode as they are molded from polypropylene and
contain only stainless steel internal parts.
Ideally a ball valve handle will be supplied pre-drilled. If not
pro-lock, only requires a 4mm hole to be drilled at a suitable point.
If this is not possible use Pro-lock ball valve locking pins
(supplied in three sizes) as in the picture below.
Pro-lock ball valve lockouts are available in red,
green, and yellow for easy identification of the employees using
the devices, the contents of the pipework being isolated, or whether
the valve is locked open, closed or part of a wider isolation.

Optional use of padlocks (maximum 6mm shackle
diameter) or seals for evidence of tamper.
