Abstract

A multifunction hydraulic flow metering valve arrangement circuit comprises a main valve (14), a bleed flow orifice (18), and a servo valve (64) acting with the main valve provides for proportional speed control for lowering loads and as an anti-cavitation check valve. Control pressure applied to a control chamber (44) acts on a piston (66) to compress spring (68) and whereby lift servo valve (64) from its seat (62), whereby the bleed chamber (42) is communicated with return chamber (38) and load pressure in the chamber (40) lifts the main valve (14) from its seat (54) to an extend determined by the control pressure. A pilot valve (20) in the circuit acting with the main valve provides the circuit with a pressure limiting relief valve facility. <IMAGE>
