The schematic arrangements of these two actions are shown in fig. These directional valves consist of a housing 1, control spool 2, control mechanism 3, and return spring 4. Directional control valve 9 spool controls code type aside bside type code 9 9m 10 10m 9s s1 s7 s2 s5m s6 spring centered. On the other hand, if the valve is handling cooling water to a reactor, the flow should be maximum in case of emergency. Usually one 43 directional control valve is used in the system, by which the necessary direction of the motion is determined. Directional control valves perform only three functions. Directional control valves can be classified in a number of ways. Directional valves type kv with direct mechanical operation by means of a lever control the direction of the hydraulic fluid medium flow. Detent in position 1, 2 and 3 marine version spring centered with straight through spool. As in digital electronics, binary valves operate either on or off. Directional control valves are probably the most common of all hydraulic components and are used to control the starting, stopping and reversal of flow in a system.
These three functions usually operate in combination. For example, if the valve is used to control steam or fuel flow, the valve should be shut off completely in case of air failure. Directional control valves all world machinery supply. Goto product focused delivery times are available only for the quantities and if applicable, the preferred options listed for the product. Even more basic than the discrete directionalcontrol valve is the binary valve.
