Valves have a prime safety function in many process industries. However the opening and closing of valves in the wrong sequence can have disastrous consequences - Causing serious or fatal injury to operating personnel, loss of product, damage to plant and equipment and pollution of the environment.

Ensuring the safe operation of valves is essential, in industries ranging from water and food
production to chemical manufacture and oil refining.
