Safety must not be left to chance Valves play an important role in many industrial production lines and energy networks. Valves perform essential functions regarding safety and process control systems. The correct setting and operation of valves is crucial for ensuring the operational safety of entire installations. Chains and padlocks do not provide adequate protection against operational error, vandalism or theft. A simple and safe-to-use interlock system guarantees the best possible protection against physical injury and/or damage to assets or the environment. Valve interlock systems...

Application: simple valve interlock The valve is open. This can be seen by the vacant upper key slot B (blue) – tOPen. The valve cannot be operated; it is locked. The lower key A (red) is trapped in the key slot. An authorised person inserts key B (blue) into the vacant upper key slot. This overrides the locking action and the valve can now be operated. The authorised person closes the valve. During operation, keys A (red) and B (blue) are both trapped. As soon as the valve lever is in its nal position, key A (red) is released. The valve is closed. The lower key A (red) can be removed. Upon...

Application: using a valve interlock system to switch media This example shows the switch over from one media (right pipe) to another (left pipe). Any mixing of both media must be avoided. The media is owing in the right pipe, where the valve is open. This is shown by the free upper key shaft A (red). It is impossible to operate the valve; it is locked. The lower key B (blue) is trapped in the shaft. The valve of the left pipe is closed, so no media can ow in this pipe. An authorised person inserts the key A (red) into the right interlock. The lock is released and the operator can close the...

System components for all applications and scales The keys to the system The valve interlocks as well as the keys are made of stainless steel. Individual coding guarantees the highest level of safety. It is not possible to have copies made of the keys (as can be done with simple padlock keys) due to the unique design and coding of each key. The coded keys have been designed with ergonomics in mind and offer ease of use due to their shape, even when wearing heavy-duty safety gloves. There is no up or down position of the key. The coded keys can therefore be inserted into the lock from either...

HSV-R valve interlocks HSV-R valve interlocks are utilised for valves actuated by hand wheels such as slide valves, gate valves or gear box operated valves. The number of rotations required for opening or closing varies depending on the type of valve. For this reason, the HSV-R valve interlocks are equipped with a count-release mechanism that adapts the locking action to the number of rotations required for corresponding nal position. In this way, any valve position can be set as the locked open or closed position. The valve interlock assembly includes a replacement hand wheel which...
