Operation
The operation of the valve is controlled by the insertion or retraction of coded keys specific to that valve. Insertion of a key will allow the rotation of the wrench to the desired position. The key will remain trapped whilst the valve is in this position or allow the removal of a second key to lock the valve in position.
Typical Application
The CBV is designed to operate as part of an integrated safety system, controlling the operation of quarter turn valves in safety critical applications. A typical example of where the CBV can be used is shown below.
