valve security: Mechanical Control and Interlock System to avoid Operating Errors at Valves

Valve interlocks and valve security 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.

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 (valve security). By using the Haake Safety Valve interlocks you can be sure the correct sequence of operating procedures will always be adhered to.

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

valve security Advantages for the User

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.
