LoTo – safe maintenance and commissioning

The Lock out, Tag out (LoTo) device is used to ensure a safe maintenance and commissioning of process plants. Energy sources will be locked and visually marked to prevent the unintentional movement of the valve.

By applying slight pressure to the hood of the valve, a positive connection to the handwheel can be established, so that this enables the valve to be closed and opened. A complete locking takes place in the closed state. There are two executions for the nominal sizes DN 40 to DN 100, which is tailored to the manually actuated VESTA® valves with stainless steel or plastic lantern. The valves can be locked in any position.
