QL valve interlocks suit all types of lever operated quarter turn valves, including ball, butterfly, and plug valves. Available in single key (QL1) or double key (QL2) versions, locking the valve in either the open or closed position, or if the QL2 version is specified, the valve can be locked in both the open and closed position, forming part of a comprehensive range of process interlock safety systems. Available with ‘tailor made’ concentric mounted bespoke valve attachments.

GL valve interlocks suit all types of handwheel operated valves, including gate, globe, and gear-operated valves. Available in single key (GL1) or double key (GL2) versions, locking the valve in either the open or closed position, or if the GL2 version is specified, the valve can be locked in both the open and closed position, forming part of a comprehensive range of process interlock safety systems.

The most common requirement for key interlocking of power-actuated valves occurs in Pig Launcher/Receiver systems, Scraper Traps and Sand Filter systems etc, where power actuated valves need to be interlocked with manually-operated valves and vessel closures.

SFC’s ‘Visual Alert’ Key Cabinets provide an effective and infallible management control system against unauthorized or inadvertent operation of interlocked valves or associated process equipment by keeping the coded keys, which initiate the operation of critical valves, under secure supervisory control. For storage, ease of access and issue, SFC’s key cabinets, provide all that is required.  Typically, a key cabinet will be found in a secure place; e.g. a control room whereby initiating keys are issued by the Shift Supervisor, Offshore Installation Manager or another person in authority. Cabinets vary in size and can accommodate from 1 – 280 system initiating (or spare) keys. Keys can be stored on hooks or holsters (The holster design provides increased capacity).

Where security lock-off devices are required to provide mechanical locking of manual operators, SFC offer a full complement of security and commissioning tools. If sequential control is unnecessary but a secure lock is required, the SFC range of security products can provide the solution you need.
