mechanical interlock: Mechanical Control and Interlock System to avoid Operating Errors at Valves

Valve interlocks and mechanical interlock are used everywhere where a sequence of valves helps protect personnel and machinery.
These are mainly:

• oil boring islands,
• chemical plants and refineries,
• or the gas industry
• as well as electricity and water suppliers.

An operating error at a valve can have dramatic consequences – personal injuries, damages to the plant, or even contamination of the environment can be a result. Thus, the safe operation of valves must be guaranteed (mechanical interlock). By using the Haake Safety Valve interlocks you can be sure the correct sequence of operating procedures will always be adhered to.

Haake mechanical interlock products can be installed at every lever-operated or hand-wheel valve, without damaging the mounting. The interlocks / mechanical interlock are robust, easily handled and clearly show every position of the valve (tOPen). Before the installation of Haake Safety Valve interlock systems (mechanical interlock), the requirements and conditions of the operation are established in co-operation with our users / customers.
