摘要

A valve group subassembly for use in a vehicle having hydraulically operable mechanisms. The subassembly includes the main valve and actuators, interconnecting duct structures, and a mounting bracket permitting the complete subassembly of the control elements. A pilot valve manifold is mounted to the bracket for hydraulic connection thereto of the pilot valves. The bracket may be resiliently mounted. The valves may be provided with removable valve stems, permitting the valve bodies to be maintained mounted to the bracket in servicing the individual valves. The subassembly is arranged to permit a bench testing thereof prior to the installation in the vehicle.
