CLAIMS

What is claimed is:

1 . A valve assembly (100) comprising:

an actuator (106) configured to move a modulating element (104) in one or more predefined directions within the valve assembly (100);

a braking assembly (108), wherein upon activation, the braking assembly (108) is configured to resist movement of the modulating element (104) in the one or more predefined directions;

a controller (1 10) communicatively coupled to the actuator (106) and the braking assembly (108), wherein the controller (1 10) is configured to control the movement of the modulating element (104) by communicating with the actuator (106) and the braking assembly (108).

2. The valve assembly (100) of claim 1 comprising a shaft, wherein the modulating element (104) is configured to move in the one or more predefined directions within the shaft.

3. The valve assembly (100) of claim 1 , wherein the braking assembly (108) comprises magnetic particles cooperating with at least a portion of the modulating element (104) to resist the movement of the modulating element (104) in the one or more predefined directions.

4. The valve assembly (100) of claim 3, wherein the magnetic particles are dispersed in one of a fluid form and a powder form.

5. The valve assembly (100) of claim 3, wherein upon activation of the braking assembly (108), the magnetic particles, under a magnetic field, bind themselves together, to thereby resist the movement of the modulating element (104) in the one or more predefined directions.

6. The valve assembly (100) of claim 5, wherein the controller (1 10) communicates with the braking assembly (108) to adjust the magnetic field to thereby control binding strength of the magnetic particles.

7. The valve assembly (100) of claim 1 , wherein the one or more predefined direction of the modulating element (104) comprise at least one of a linear direction and a rotational direction.

8. The valve assembly (100) of claim 1 , further comprising a sensor communicatively coupled to the controller (1 10), wherein the sensor is configured to:

sense a current position of the modulating element (104); and

generate a feedback signal indicating the current position of the modulating element (104).

9. The valve assembly (100) of claim 8, wherein the controller (1 10) is further configured to:

upon receiving the feedback signal, communicate with the actuator (106) and the braking assembly (108) to control the movement of the modulating element (104).

10. The valve assembly (100) of claim 1 , wherein the actuator (106) is a solenoid.

1 1 . The valve assembly (100) of claim 10, wherein the controller (1 10) communicates with the actuator (106) to adjust an input electrical supply to the actuator (106).

12. A braking arrangement for a valve assembly (100), the braking arrangement comprising:

a braking assembly (108), wherein upon activation, the braking assembly (108) is configured to resist movement of a modulating element (104) in one or more predefined directions, wherein the modulating element (104) is actuated to move in the one or more predefined directions by an actuator (106); and

a controller (1 10) communicatively coupled to the actuator (106) and the braking assembly (108), wherein the controller (1 10) is configured to control the movement of the modulating element (104) by communicating with the actuator (106) and the braking assembly (108).

13. The braking arrangement of claim 12, wherein the braking assembly (108) comprises magnetic particles cooperating with at least a portion of the modulating

element (104) to resist the movement of the modulating element (104) in the one or

more predefined directions.
