Abstract
Method and apparatus for isolating hydraulic devices in a stacked hydraulic circuit of modular design employing an isolator valve module which enables partial and/or complete isolation of components in a hydraulic system to be isolated for inspection, testing, maintenance or replacement, by selective operation of the isolator valves in the isolator valve module. The isolator valve module may be a sub-plate module supporting other modules or a plurality of stacks of modules or may be a 'sandwich' type module sandwiched between a sub-plate and another module or between two sandwich-type modules.
