Hydraulic Central Manifolds
Hydraulic Central Manifold Housings was a hydraulic manifold block at the centre of small hydraulic power unit, it is a hydraulic manifold which connect motor and pump/tank .This central manifold suppose to give both a single and double acting hydraulic circuits.
Each central hydraulic manifold block is designed to contain cartridge hydraulic valve cavities which are an Industry Common Cavities (ICC) size 3/4″-16UNF, size 8.
The screw in hydraulic cartridge valves functions:-
Cartridge Relief valve: standard valve adjustable from 40 bar up to 315bar
Flow control valve: control hydraulic cylinder speed, only control cylinder down speed if the hydraulic system is single acting application.
Cartridge Check Valve: Hold pressure in P line, keep single acting hydraulic cylinder stay.
Lowering Valve Cavity: This cavity normally fitted with a solenoid valve which can be normally closed ,sometimes with a normally open solenoid cartridge valve . Alternatively a manual lowering valve can be fitted to control the lowering with a handle lever valve.
The central hydraulic manifold block is designed mounting faces with 2 * M10 – 82mm threads.
Pressure and return connections thread are normally 3/8″ BSPP Ports, either 1/4″BSPP available . Sometimes we can add modular CETOP 03 valves using stackable valve manifold block to connect central manifold.
All of central manifold material is 6061-T6,some of them are just machining ,some others are die-casting hydraulic manifold .You can click here download Hydraulic Central Manifold PDF information.
