Thanks to this type of valves, it’s possible to regulate flow passage inside an hydraulic circuit. The flow restriction brings about a non-compensated load loss which depends on the loads themselves.These valves allow to obtain compensated flow regulators, when coupled with pressure compensators.

These valves regulate flow passage only in one direction, keeping the flow passage free in the opposite direction. Flow restriction brings about a non-compensated load loss which depends on the loads themselves. These valves act as compensated flow regulators, when coupled with pressure compensators.

These valves regulate oil flow inside an hydraulic line, independently from the feeding pressure.They are composed by an adjusting device for flow setting and a pressure compensator connected to it in series which keeps a constant pressure drop across the adjusting device flow area. 2-way compensated flow regulators are usually installed in parallel to the main line: 1) to reduce feeding on secondary circuits, which work at lower pressures compared to the main feeding line pressure; 2) to reduce inertial/dragged maximum speed. In the first case, it’s important to provide draining of oil in excess in comparison with set flow, installing a pressure relief valve.

These valves regulate oil flow inside an hydraulic line, draining excess flow through a third line which makes the regulated flow independent from the working pressure.

There are different types of 3-way regulators:

Cartridge type: this type is very compact and enable a constant regulated flow, independently from pressure on both lines. The excess flow line can be pressurized even at higher values than the regulated line. Regulated flow has priority over any line connected to the excess port.

Integrated circuit type: these valves are flow regulators designed using cartridges installed in a manifold. Their main characteristic is that they’re able to manage higher flows than the cartridge type. Main components are: (1) flow control device; (2) 2-way normally closed compensator.For an optimal functionality, pressure on third line (T) must be lower than pressure on regulated line (A).

3-WAY COMPENSATED FLOW REGULATORS

These valves enable the division of the inlet oil flow(3) in equal parts or with a predetermined ratio on ports (2) e (4), so that flow onto the actuators is pressure compensated. This function is guaranteed also in the opposite direction, where the flows from the hydraulic actuators are reunified in port (3).

2-way N/O pressure compensators are cartridges designed for 3-way cavities, which allow to obtain 2-way compensated flow regulator, since they are series connected to a flow restrictor or to a 2/2 proportional valve.

2-WAY N/O PRESSURE COMPENSATORS

16.04 79

2-way N/C pressure compensators are cartridges designed for 3-way cavities, which act as a 3-way compensated flow regulator, since they are connected in parallel to a flow restrictor or to a 2/2 proportional valve. For an optimal functionality, pressure on port (2-T) must be lower than pressure on regulated line (3-A).

3-way post-regulated pressure compensators are cartridges designed for 4-way cavities.If connected to a flow restrictor or to 2/2 proportional valve, they act as a 3-way compensated flow regulator, which enables a constant regulated flow independently from the pressure on ports (4) and (2). As its main characteristic, this type of compensator is able to feel the pressures to be balanced on line (4-A), i.e. it’s able to work on regulated line pressure. So that it’s possible to regulate pressure or even to intercept regulated flow, by adding the necessary components. Feeding circuits for accumulators (braking systems) are interesting applications of these type of compensators.

4-way pressure compensators are cartridges designed for 4-way cavities. Connected to a flow restrictor or to a 2/2 proportional valve, they act as a 3-way compensated flow regulator which is able to keep a constant regulated flow independently from pressure on ports (2) and (3). As its main characteristic, this type of compensator is able to feel pressures to be balanced on line (4-IN), i.e. It is able to work on pressure picked up-stream the compensator. Only flow regulations can be done with this type of compensator.
