3 MONOBLOCK DIRECTIONAL CONTROL VALVE TYPE RM0 GENERAL DESCRIPTION Document: MDCV-1-Sept 015 Hydraulic valve RM0 provides change of fluid flow direction, hydro-systems pressure restriction, pump unloading in neutral position of the spools. The valve RM0 is designed to be integrated in hydraulic systems of Mobile and Industrial Machines. The valve assembly consists of: A body with integrated relief and check valve, spool, control and spring-centering group of the spool. The valve RM0 provides direct passing of the flow from the pump line to the tank at neutral position (open center). Options closed centre and carry over are possible with additional adapters. There are different control options: spring centering in neutral position, detent, automatic kick-out, hydraulic and electro-hydraulic control.

20 MONOBLOCK DIRECTIONAL CONTROL VALVE TYPE MRP70 GENERAL DESCRIPTION 1. The valve type MRP 70 incorporates the features of a 4-way directional control valve, an adjustable full range pressure compensated by-pass type flow control valve and a pilot operated pressure relief valve all in one compact package.. Less fittings and plumbing, eliminates leakage points.. Fine positive metering is possible in either direction with one manually adjustable, infinitely variable lever controlling both direction and amount of flow. Amount of flow is proportional to movement of the lever. 4. Flow is constant regardless of pressure variations, thus flow out the work port remains smooth and constant regardless of changes in load conditions. 5. An externally adjustable pilot relief is standard. 6. Friction detent (Friction positioner kit).
