2 6/2 DIRECTIONL RS.. The solenoid directional control valves of the RS type are used to control the motion of one or more consumers. Usually one 4/3 directional control valve is used in the system, by which the necessary direction of the motion is determined. The flow from it is fed to a directional control valve of the RS type, which specifies which one of the consumers will function. In case of more than two consumers, one additional RS directional control valve is added for every following consumer.the stacking of the directional control valves (up to 10 units) is realized by pins and nuts, and the sealing between them is fulfilled by frontal O-rings. This pattern provides an economy of one solenoid per each consumer and an improved compactness. Three types of solenoids are manufactured, which differ by the nominal flow RS04 (10 L/min), RS06 (30 L/min) and RS10 (50 L/min),as the maximum pressure for all of them is 250 bar. RS06..T and RS10..T for maximum pressure of 350 bar are offered out of the options RS06 and RS10. They have one additional port T, which leads the leakages out of the chamber of the directional control valve and has to be connected to the tank. The maximum allowed pressure at port T is 200 bar. If a hydraulic lock for the consumer is needed, there is an opportunity for direct assembly of a hydraulic lock type VBD-R-38 (only for a RS06..V directional control valve). 4/3DV P T BV99 RS06 RS06 VBD R 38 Page 1.1

When a flow is fed to the port P of the block, the cylinder makes one full cycle of retraction and extension and keeps hydraulically locked, despite the fact that there is pressure at the input port. It is necessary to wait for 3-4 seconds after the feed of the flow stops, till the next action, in order to restore the position of the switching spool in the directional control valve. On the next flow feed the cycle repeats itself.

18 ELECTRO-HYDRULIC OPERTING UNIT EHO..-.. The electro-hydraulic operating unit EHO is designed for coupling to manually operated, hydraulic directional control valves of the P40 and P80 types, which are produced by the Bulgarian company BDESHTNOST D, as an additional option for electric operation. It can be mounted on a monoblock or sectional implementation, with no limit to the number of the sections. It is fixed by two screws M6 at the place of the decorative cap, closing the spring package of the section. The existing screw, which holds the spring, is removed and the connector of the unit is screwed on its place. The hydraulic inlets and outlets of all the sections are joined together by a strip, which is fixed by two screws to each section. The oil supply can be realized in two ways: - from external source with pressure between 10 to 20 bar; -from the flow which supplies the directional control valve. For that purpose, some flow is directed from one of the inlets P, by a pipe and a nipple to a reducing valve, mounted on the collector and providing the necessary supply pressure. The outlet line is connected to the free outlet T of the directional control valve by a special transient nipple. The connections are made by ø8 steel tubes. To provide minimum pressure of 10 bar in the case of non-operating (unloaded) directional control valve, a back pressure valve VR4 is mounted in the seat N, designed to maintain the minimum pressure during the running of the flow. The electro-hydraulic operating unit is shown below, mounted on a double monoblock directional control valve P80 with own supply. 1. Directional control valve 2R80 2. Reducing valve 3. Collector 4.
