Valve Interlocks are used everywhere 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 catastrophical 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.

The HSV-Q is designed to operate as part of an integrated safety system- Controlling the operation of valves in safety and process critical applications.  The operation of the valve is controlled by the insertion or retraction of coded card keys specific to that valve.  Insertion of the change key will allow the rotation of the lever to open or close the valve.  After operation the change key will remain trapped.  The second key is now released and transferred to the next valve interlock in the sequence.
