Multi Rotation Lock - MRL (trapped key interlock)
The Multi Rotation Lock (type MRL) is suitable for all hand wheel-operated valves like gate-, globe- and gearbox-operated valves.
The MRL can be mounted without any alteration to the host valve, and the characteristics of the valve remain unchanged. The lock is installed as an integral part of the valve, with the original hand-wheel removed and replaced with a new, same-sized Stainless Steel hand wheel.
