Security interlocks

SMIT FLOW CONTROL is specialised in the manufacture of security interlocks.

In the security interlocks, a locking device will be mounted onto the valve that operates with a special key. The key can be kept, for example, in a control room of the production plant on a special key stand.

A valve fitted with a security interlock cannot be operated before the security mechanism has been released with an individualised key.

Also locking possibilities for systems

In addition to the operation of individual valves, the Interlock system is also suitable for the security locking of valve groups, when it is important to operate certain valves exactly in the predetermined order.

The Interlock security locking can be applied for all valve models and nominal sizes and it is also easy to install afterwards.
