Pressure Reducing Valve
In contrast to pressure relief valves, which affect the level of input pressure (i.e. pump pressure) fed into the hydraulic system, pressure reducing valves are used to influence the output pressure of the hydraulic system to a subsystem (e.g. actuator pressure).
Reducing the input pressure (primary pressure) or maintaining a particular output pressure (secondary pressure) is achieved at a set value which is below the varying pressure occurring in the main hydraulic circuit. It is thus possible to reduce the pressure in one part of the circuit to a lower level than the system pressure.
Note: the pressure control valve is normally open.
Flow Control Valves
Flow control valves manage the flow by decreasing or increasing the opening at the throttling point. This helps to determine speed of movement for the actuators. The simplest design for a flow control valve is a needle or longitudinal slot mounted in the pipeline and connected to a screw that adjusts the opening at the throttling point.
These are called throttle valves and they are regularly used in combination with a check valve, i.e. the throttle check valve for speed control in one direction of flow. A disadvantage of throttle valves is that at varying loads a change in pressure drop will change the flow; thus, the speed of the moving actuator will also be affected. Flow control valves are divided into two types:
Throttle valves (flow depends on Δp)
- Viscosity dependent
- Viscosity independent
Flow control valves (independent of Δp)
- 2-way flow control valves
- 3-way flow control valves
The difference in pressure before and after the throttling point, i.e. the pressure drop (Δp), determines the rate of flow through the throttle valve at a particular setting. If the pressure drop over the throttling point remains the same, the flow of oil that passes the throttling point remains the same as well. This allows operation at constant speeds, regardless of the load.
Flow control valves are used to influence the speed of movement of actuators by changing the opening for the flow (decreasing or increasing it) at the throttling point. In fact, these are two flow control valves placed in series and built together. The throttling point operates at a fixed setting, but the throttle opening before the throttling point varies with pilot pressure of the load.
Note that flow dividers have a certain special standing: they divide an oncoming flow into two or more flows. Usually it is used to distribute the flow of a single pump to two or more sub-systems that have different operating pressures.
Throttle Valve
Throttle valves come in piston and needle-valve structures, but we also know them as turn plugs with axial or radial grooves. The smothering of grooves is more accurate but provides more variability than those with piston structures. The needle throttle has one disadvantage: a great deal of power is required to move the needle only a slight amount.
The pressure difference (Δp) determines the amount of flow that passes the throttle. In systems with varying loads (and therefore varying pressures), the flow passing the throttle will always be different.
You can find non-adjustable (fixed) smothering in situations where it is needed to gauge against excessive pressure surges. Also, one can find non-adjustable throttles in control systems.
Flow Control Valve
A pressure-compensated flow control valve has a fixed throttling flow at all pressures. The two-way pressure-compensated flow control valve is also called a series valve. The pressure reducing valve and the smothering of this valve are placed in series with each other. At a three-way pressure control valve, the pressure relief valve and the throttle in this valve are parallel to each other.
The two-way and three-way pressure compensated flow control valves are quite similar. The only difference is that in the latter type, the excess oil flow is not drained through the pump s safety valve but through the flow control valve itself. The pump pressure for a three-way pressure compensated flow control valve is always equal to the pressure exerted by the actuator plus the spring pressure.
Note that using three-way flow control valves increases efficiency because the system pressure will never be higher than as required for moving the load. With two-way flow control valves, this is not the case because the pump keeps feeding the system with oil until the preset pressure of the pump's safety - pressure relief - valve has been reached.
Electro Hydraulic Valves
When your hydraulic application requires a very accurate control of the flow, hydraulic valves may be equipped with advanced control electronics. This allows the use of inductive path measuring devices that monitor the position of the spool continuously to ensure optimum position of the spool.
Proportional hydraulic valves are able to control the opening to flow proportionally instead of gradually, as is the case for most standard hydraulic valves. The simplest type of proportional hydraulic valve is a variable throttle controlled by a manual lever, as illustrated below:
Proportional and servo hydraulic valves are usually classified as high-performance valves. This distinction gives an expected indication of performance, which tends to generalise the true differences between various types of servo and proportional hydraulic valves. Each type has its own unique performance characteristics either in controlling pressure or controlling flow.
Servo hydraulic valves use closed-loop control to monitor and feed back the main-stage spool position to a pilot stage (hydraulic/pneumatic) or driver (electronic). Proportional hydraulic valves, on the other hand, move the main-stage spool in direct proportion to an external piloted control signal and do not have any means of feedback within the valve.
Servo Hydraulic Valve
The main stage spool of a servo hydraulic valve is equipped with a path measuring system for accurate adjustment. This system measures the exact position of the main-stage spool and feeds its position directly to the electronic control unit. If sworn position is not consistent, the control signal corrects the position of the main-stage spool.
Servo hydraulic valves are widely used in aerospace and industrial applications.
Proportional Hydraulic Valve
The most common proportional hydraulic valves are directional control valves, pressure relief valves, flow controllers and adjustable throttling. Proportional hydraulic valves convert an incoming mechanical or electrical signal directly proportional to a shear mode. The movement follows a continuously incoming signal. Different types of available proportional hydraulic valves are:
- Various directional control valves
- Flow control valves
- Pressure relief valves
- Pressure reducing valves
- Counter balance valves
Typical applications of proportional hydraulic valves include cranes and industrial applications such as injection moulding.
