Valve control for several users actuated in parallel - has arrangement of control edges to give symmetrical layout

The valve arrangement is for the control of several hydraulic users actuated in parallel. The speed determining piston section is arranged between housing chambers (11a,11b) which combine into a common inlet and outlet channel (P,P'). The housing chambers (11a, 11b) have control edges (13a, 13b...

More Information
Summary:The valve arrangement is for the control of several hydraulic users actuated in parallel. The speed determining piston section is arranged between housing chambers (11a,11b) which combine into a common inlet and outlet channel (P,P'). The housing chambers (11a, 11b) have control edges (13a, 13b) which work in conjunction with the corresponding control edges (12a, 12b) for the control piston section (21a). USE/ADVANTAGE - Valve arrangement which allows a symmetrical layout for the position control valve, and avoids the danger of a pressure drop to the user.
