Interlocking. In a fraction of the space

Fluid Interlocks compact design brings minimal installation height fitting easily into any project. Avoiding any possible interference with other valves or pipelines in the field.

Near seamless design

The most efficient way to protect systems from contamination in the harshest environments is by reducing seams and screws. That’s why we reduced over fifty percent of the number of screws and made the design almost seamless.

Secured Tagplates

We believe that text-plates used for key and interlock identification need to be fastened with screws so a small but essential part of the system is secured.

Revolutionary valve counting mechanism

Fluid Interlocks’ patented valve counting mechanism is engineered and constructed to ensure the “locked open” and “locked closed” position of the interlocked valve. The mechanism will never skip, slip or miss and is build to last. Set and forget.

Multidirectional lock-portions

We believe that user-friendliness of the Fluid Interlocking systems will improve process safety. Therefore we designed a multidirectional lock-portion. No matter which way the valve is orientated, the lock-portions can always be mounted in the user-friendliest way.

Easy Installation

Fluid Interlocking systems are designed to fit effortlessly without modification on any valve and can be installed on a live plant.


Smooth operation

Lockportion and key are modular designed to smoothly drive the locking and unlocking mechanisms in the different models of Fluid Interlocking systems. Setting the codings in both key and lock is a very efficient process and makes same day shipping possible.
