PARTS IN BODY FLOW CONTROL VALVES
The main characteristic of Flow control valves described in this chapter is that compensator and flow regulator are mounted directly inside the manifold, so that this type of valve is directly installed in the hydraulic circuit. There are 2 different types of flow control valves, according to the type of adjuster: • Electro-proportional flow regulators • Manual flow regulators
3 WAYS IN LINE MOUNTED FLOW REGULATORS Whatever working pressure is, 3-way flow regulators grant a constant adjustment of oil flow inside an hydraulic line (A), draining excess flow through a third line (T). Main components are: an flow regulator device and a 2-way NC compensator. To have an efficient functionality, pressure on third line (T) must be lower than pressure on regulated line (A). P

FLOW REGULATORS FOR EARTH MOVING MACHINES Flow regulators for Earth movement machines are hydraulic valves designed to allow the installation of hydraulic hammers, trenchers and/or other hydraulic tools on excavators, backhoes and/or other machines. Flow regulators for earth moving machines are designed in two different types: 2 way or 3 way valves. They are equipped with: (1) relief valves, to reduce pressure on regulated line; (2) dump electric valves. OUT

PARTS IN BODY FLOW CONTROL VALVES
To have an efficient functionality, when flow control valve is not operating, it is necessary to assure at least 7.5 bar pressure on the regulated port (OUT or P). For applications linked to hydraulic motors or open-centre direct control valves, the installation of a 7.5 bar-pre-loaded uni-directional valve is required.

- Flow (OUT) can be regulated at the required value, acting on adjustable screw (pos. 3); flow increases when the screw is turned clockwise. - Max leakage in T: 3l/min. - Max backpressure in T: 1,5 bar. - For optimal functionality of the compensator, when the electric valve (CT2) is open, it’s important to make sure that regulated line OUT is pressurized at 7,5 bar at least. If not, a unidirectional valve must be installed, to supply the required backpressure (see pag. 182-183). - Check valve on port LS requires dumping of Load Sensing line, through a compensated draining, when electric valve is open (CT2). - For applications which need Post-Compensated directional control valves, refer to schemes 2 and 3, in which there is an LS check valve. - For applications which need Pre-Compensated directional control valves and direct connections to variable piston pumps, refer to schemes 4 and 5.
