QL quarter turn locks are a smart option for securing your quarter turn manual valves. Suitable for all types of lever valves, such as ball, butterfly and flap valves, they ensure that your operators follow the process steps correctly. Available in single or double key versions, they can lock the valve in the open, closed, or both positions.

Integrating actuators into valve locking procedures is often necessary. MOV interlocks provide a solution by regulating actuator components, mechanically blocking the power switch, manual override function and position indicator. These interlocks are designed to fit electric, pneumatic and hydraulic actuators.

Safely opening a scraper station door is essential to avoid potential dangers. By locking the aeration and drain valves with the closing door, you guarantee the absence of residual pressure in the tank, thus ensuring total insulation. Interlocks also allow other functions such as purging and flushing to be integrated, providing safe access for operators.

The Sequence Control Unit (SCU) is an essential mechanical device for carrying out complex operational processes. Placed locally on valve systems, it guides operators through non-linear sequences, ensuring safe operations.

The Key Exchange Box (KEB) is an essential device for safe operations. Used in various contexts, it allows one key on a switch to release several other keys, thus ensuring secure access to several hatches or devices.
