Parker FM2 DDV Flow Control Valve

Double-throttle check valves from the Parker Manapak series FM are sandwich plate valves designed for stacking beneath a directional valve with a standard mounting pattern. Throttle and check valves are arranged in ports A and B. By altering the mounting position (FM2 and FM3) or internal compenents (FM4), meter-in or meter-out flow control functions can be selected. The throttle check valve can also be used to influence the switching time of pilot operated directional valves. In this case, the valve is positioned between the pilot stage (CETOP03, NG6) and the main stage (CETOP05, NG10 up to CETOP10, NG32). The FM6 valve is only available as meter-out.
