  • Fluid control valve systems, fluid systems equipped therewith, and methods of using
    Patent number: 9200648
    Abstract: A fluid control valve system suitable for use in fluid systems. The valve system includes at least one check valve assembly that has a controllable bidirectional flow capability. The valve system and its check valve assembly can be installed in a fluid system that contains a pump/motor to enable the displacement output of the pump/motor to be controlled. The valve system further includes a pilot valve assembly and a device for controlling the check and pilot valve assemblies. The controlling device is adapted to control the pressure of at least one pilot fluid delivered to the pilot valve assembly, which enables the check valve assembly to selectively check flow of a working fluid flowing therethrough in either of two directions.
