Valve interlocks are used everywhere where a sequence of valves
helps protect personnel and machinery.
These are mainly:
◦offshore applications,
◦chemical plants and refineries,
◦or the gas industry
◦as well as electricity and water suppliers.
Valves have a very important safety function in many industrial
processes.
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.
By using the Haake Safety Valve interlocks you can be sure
the correct sequence of operating procedures will always be adhered
to.
Haake products can be installed at every lever-operated or
hand-wheel valve, without damaging the mounting. The interlocks are
robust, easily handled and clearly show every position of the valve
(tOPen).
Before the installation of Haake Safety Valve interlock systems,
the requirements and conditions of the operation are established in
co-operation with our users / customers.
Valve interlocks can only be used when both keys are inserted in
the interlock. Both keys are individually coded. A key with the
wrong coding cannot be inserted in the interlock respectively
cannot open this. Each key can only be removed when the valve is in
a certain position. Once one key has been removed, the other one is
trapped in the interlock.
Interlocking systems for lever-operated valves are distinguished by
the fact that the position of the removed keys corresponds with the
final position. This guarantees the removal of one key only when
the valve is fully open and the removal of the other key only when
the valve is fully closed. Interlocking systems for hand-wheel
operated valves are used for different applications. With these
systems the final position can generally be adjusted. Often the
final position is selected as “Valve fully open” and “Valve fully
closed”. But other valve positions are also possible. For this,
there is one key/lock for every final position. A key can only be
removed from the defined final position.

◦Existing hand wheel can be re-used in most applications
◦„Anti tamper“ fixings available to avoid unauthorized operation of
valves
◦No padlocks which could be removed easily
◦Safety coded keys, which cannot be copied readily
