Valve Interlock

Valves have a prime safety function in many process industries. 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.

The HAAKE TECHNIK range of valve interlocks not only control the opening and closing sequence of process valves but also prevent their unauthorised operation. The interlocks are manufactured from stainless steel, maintenance free, tamper proof, robust, reliable, resistant to sand, dirt, snow, ice and moisture ingress, easy to operate, show clearly the condition of the valve and can be fitted to every type and size of valve in service without breaking the pressure seal.
