Abstract of the Disclosure A unitary pilot-operated bi-directional cylinder lock valve and pressure-compensated flow control valve arrangement, having a common housing with internal porting connecting a pair of oppositely acting normally closed check valves operated to open by fluid pressure in one direction thereagainst on the inlet side and by a common free-floating inlet-pressure-responsive pilot piston therebetween. Also in the common housing and ported in line with each of the check valves are two pressure- compensated flow control valves which restrict fluid flow through the check valves as a function of flow pressure. The pressure-compensated flow control valves are also oppositely acting and each senses and acts to reduce fluid flow in response to pressure build-up in and opposite direction from that of the other. The unitary lock valve and pressure- compensated flow control valve is connected in line with one or more hydraulic cylinders of an operating table or other hydraulic cylinder- operated apparatus, with the exit/entrance ports from the pressure- compensated flow control valves connected to the opposite ends of the hydraulic cylinder or cylinders.
