The Bosch Rexroth FESE63CA-3X/1800LK0G1V (R901276354) is a sophisticated pilot-operated way proportional throttle valve designed for block installation, offering precise flow control in hydraulic systems. This valve is engineered to regulate flow continuously by controlling the position of its orifice spool through command value-dependent feedback. The FESE63CA-3X/1800LK0G1V features integrated electronics with a position transducer that ensures accurate spool positioning by comparing actual and command values, making real-time adjustments via the proportional solenoid. The valve's construction includes a cover with pilot oil connections, a main valve with an orifice spool, a pilot control valve with a proportional solenoid, and integrated electronics. Its area ratio allows for efficient flow control in various sizes (NG6 to NG25), and it offers the flexibility of external pilot oil supply via port X. In case of an enable signal disconnect, the orifice spool moves to block the flow direction from A to B without leakage. This model is capable of operating in both flow directions A to B and B to A, ensuring versatility in application. It can be paired with a pressure compensator for load-compensated flow control, enhancing its capability in closed-loop systems. The unit comes fully adjusted with onboard electronics (OBE), and it offers options for voltage or current interface connections. In terms of safety features, Bosch Rexroth has incorporated fail-safe measures that de-energize the solenoid during supply voltage failure or cable breakage in the position transducer, causing the spool to block the flow automatically. However, users should note that sudden stoppage due to voltage failure may result in machine damage due to acceleration forces. Designed according to DIN ISO standards for installation dimensions, this model boasts maximum operating pressures up to 350 bar and is available in various sizes denoted by its component series X designation.

Pilot-operated 2-way proportional throttle valve in block installation technology Installation dimensions according to DIN ISO 7368 Orifice spool electrically position-controlled Flow in both directions In case of power failure, cable break or disconnection of enable, the orifice spool will automatically move into seat position and block the flow in both directions Can be used for pressure-compensated closed-loop flow control in conjunction with a pressure compensator Completely adjusted unit with integrated electronics (OBE), optionally available with voltage or current interface

Valves of type FESE are pilot-operated 2-way proportional throttle valves for block installation for the continuous control of flows.

Technical set-up:

The valve consists of four main assemblies:

Cover (1) with connection surface for pilot oil connections Main valve (2) with orifice spool (3) Pilot control valve (4) with proportional solenoid (5) Integrated electronics (6) with position transducer (7)

General function:

Command value-dependent position control of the orifice spool (3) and thus defined opening of the orifice (8). The flow depends on the Δp across the orifice (8) and the position of the orifice spool (3). Actual value recording of the orifice spool (3) position by the position transducer (7); command/actual value comparison in the electronics (6); variations are prepared and forwarded as control output for correction of the orifice spool (3) position to the proportional solenoid (5) to the pilot control valve (4). Area ratio of area (14) to area (15) = 2 : 1 for NG25; 32; 40 and 1.6 : 1 for NG50; 63. Flow direction A → B (connect X to A); Flow direction B → A (connect X to B); External pilot oil supply possible via X. When the enable is disconnected, the orifice spool (3) will move onto the valve seat (9) and block the flow direction A → B in a leakage oil-free manner. The spool seal (11) seals port B to the control chamber (12) in a leakage oil-free manner; with internal pilot oil supply observe leakage oil from X via the pilot control valve to Y! Orifice spool position at command value 0 V or 4 mA already regulated, whereas the orifice (8) is still located in the positive overlap.

Open orifice spool function:

(Assumption flow A → B and A connected to X)

The proportional solenoid (5) moves the pilot spool (4.1) against the spring (13) and opens the connection from control chamber (12) to Y; pressure reduction in the control chamber (12) and movement of orifice spool (3) in opening direction by the pressure in A on the area (15) plus the pressure n B on the annulus area (16).

Close orifice spool function:

(Assumption flow A → B and A connected to X)

Flow reduction in the proportional solenoid (5); the spring (13) moves the pilot spool (4.1) against the proportional solenoid and opens the connection from X to the control chamber (12); pressure build-up in the control chamber (12); pressure on the areas (14) plus spring force (10) move the orifice spool (3) in closing direction

Flow control function:

Can be used in connection with a pressure compensator for the load-compensated control of a flow

Supply voltage failure:

The integrated electronics de-energize the solenoid in case of supply voltage failure or cable break in the position transducer (7) The pressure applied to control port X plus the spring force (10) move the spool onto the valve seat (9) where it blocks the flow A → B.

Notice;

Failure of the supply voltage will lead to an abrupt standstill of the control axis. The acceleration forces occurring in this connection may cause machine damage!

1)	Measuring conditions: pressure in A = 50 bar; actuator in B closed (pA = pB = 50 bar); pressure in A < 50 bar → actuating time increases; pressure in A > 50 bar → actuating time decreases; changes in the actuating time are influenced by the area ratio of the orifice spool as follows:→ command value 0 → 100 %: The actuating time decreases the higher the inlet pressure and the smaller the Δp across the valve is. → Command value 100 → 0 %: The actuating time decreases the higher the inlet pressure and the larger the Δp across the valve is.

Function

1. Switch-on procedure/Fault behavior:

After applying the supply voltage of 24 V, the electronics are ready for operation provided that the following conditions are met:

The operating voltage UB > 18 VDC The internal supply voltage ± 7.5 V is symmetric The connection to the position transducer is not interrupted. The command value line is not interrupted (only with 4 mA ... 20 mA interface)

If one of the conditions is not satisfied, the controller and the output stage are blocked and the ready for operation signal is set to < 8 V.

2. Normal operation

With inactive enable (< 8 V) and any command value presetting (0 ... 10 V or 4 ... 20 mA), the orifice spool rests against the stop and blocks the flow from A to B.

By applying a voltage > 10 V at the enable, the position controller for the orifice spool and the output stage for the pilot control valve are activated. Simultaneously, the actual value from the orifice spool position is compared to the applied command value in the position controller (PID) and a control output is sent to the output stage which changes the solenoid current until the orifice spool position corresponds to the command value.

The actual value of the orifice spool position is recorded by an inductive position transducer. Its signal is rectified by the demodulator and fed back to the PID controller.

The following are available as output signals at the connector:
