GL VALVE INTERLOCKS FOR HAND OPERATED VALVES

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.

They are also available with ‘tailor made’ concentric mounted bespoke valve attachments.  The interlocks can be fitted to the valve during live process without the need to shut-down the system nor does it compromise the certified pressure envelope of the system.  The lock body is permanently marked with the desired plant identifiers or ‘tag’ numbers.

When used with other SFC interlocks, operators are compelled to follow the correct sequence of operation of all valves within the interlock sequence. The lock incorporates a counting mechanism, which is commissioned after installation to trap and release keys at the desired position.
