Valve locking systems

Fittings and valves play a key role across a range of industrial production lines and energy networks. In these areas, they perform important safety and process control functions. Therefore, their correct setting and operation is crucial for the functional safety of entire plants.

In this context, chains, padlocks and organizational measures such as Lockout-Tagout procedures (LOTO) do not provide sufficient protection against incorrect operation.

The key to system and process safety is the use of valve locking systems.

What is a valve locking system?

Valve locking systems provide a fail-safe system for controlled opening and closing of valves. They are used when a specific opening and closing sequence for multiple valves is involved for the purpose of preventing accidents, protecting materials or ensuring process safety.

A simple and secure interlock system guarantees the best possible protection against physical damage and/or damage to assets or the environment.
