In this video i explained construction , working and symbol of proportional directional control Valve A proportional directional control valve enhances hydraulic system precision by modulating fluid flow in proportion to input signals. It offers variable control over direction and flow rates, enabling smooth, proportional movements in machinery. Utilizing advanced electromechanical or electrohydraulic principles, it adjusts flow output with high accuracy, crucial for applications requiring precise speed, force, or position control. This valve type optimizes energy efficiency, reduces heat generation, and prolongs component lifespan. Its versatility in industrial automation and mobile equipment makes it indispensable for tasks demanding fine-tuned operational control and reliable performance across dynamic operating conditions.

very nice video
Nice
Nice vedio
Sir plunger pump and vane pump in high and low pressure pump per vedio bano please
Thank you for your comments.
Pump ke upar bhi video banayenge
Nice vedo in ahydraulic knowledge
Plz ak hydraulic calculation pr bhi vedo banaaiye plz sir
Sir aap ka pH no kya plz send me
Thank you brother aap meri video ko itna pasand krte ho lekin brother mobile no. Dena thoda muskil he 🙏 kya he log fir paresan krne lgte he aap ko jo bhi Queries hai aap muze mail kro muz se jitna ho skega me solve krne ki koshish krunga. Or brother ek bar fir thank you video ko like share and comment ke liye.

Thoda time lagega lekin bnaenge hydraulic calculation ke upar bhi video
Hello sir please make a informative video about borewell drilling machine
Ok brother
Hydraulic Slip ring pe ak video bano ji
Ok brother
@@JPhydrauliccircuit video bana kar link mere ko send kar kar dena comment me
Ap se behtar koi v muje hydraulic nahi samja paya bhai very good 👍💥😊
Bhai apse ak question hai
Hydraulic system me yadi ak propesanl valve lagaye to baki pressure control, follow control ho jayega ....iske liye koi other follow control valves lagane ki jarurat nahi hai n ?????
2. Cylinder me ap bole ak sensor rahta hai and sensor proportional valves ke amplifier ko camand deta hai o kon sa sensor hai or o cylinder me kaha kaha laga hota please bataye bhai ............
# hum Wind Turbine Mechanical Engineer hai 😊
Thank you brother for your comments 🙏
Proportional directional valve cylinder ya motor ka pressure , or flow Control kr lega lekin pure system ka nhi esa nhi he ki aap pressure relief valve hi na lagao thik hai pressure relief valve lgana pdega system ka pressure released krne ke liye.
Wese me bhi vestas wind systems india ke sath kam kr Chuka hu
Proportional directional control Valve jyadatar Bina feedback ke kam krte he jesa ki mene video me btaya bhi he sirf kuch hi jo closed loop yani feedback pe kam krte he
In a hydraulic closed -loop system, the sensor used to identify cylinder movement is typically a position sensor, specifically designed to measure the linear displacement or position of the hydraulic cylinder's piston or rod. This sensor is crucial because it provides feedback to the servo valve controller, allowing it to precisely regulate the flow of hydraulic fluid and thereby control the position or movement of the cylinder.
Installation of the Position Sensor:
The position sensor is usually installed in one of the following ways:
Directly on the Cylinder (External Mounting):
Rod-End Mounting: The sensor can be mounted on the rod end of the hydraulic cylinder. It moves with the rod as the cylinder extends and retracts.
Cap-End Mounting: Alternatively, it can be mounted on the cap end of the cylinder, typically in applications where rod-end mounting is not feasible or practical.
Internal Mounting:
In some hydraulic cylinders, especially those used in high-precision applications or where external mounting is not desirable, the position sensor may be installed inside the cylinder itself. This can involve integrating the sensor into the cylinder's construction or using specialized designs where the sensor is protected from the hydraulic fluid environment.
Functionality and Importance:
The position sensor continuously measures the displacement of the cylinder's piston or rod and sends this information back to the servo valve controller. The controller uses this feedback to adjust the flow of hydraulic fluid to the cylinder, ensuring that it moves to the desired position accurately and precisely. This closed-loop control mechanism is essential for maintaining position accuracy, achieving smooth operation, and responding to dynamic changes in the system.
Types of Position Sensors:
As mentioned earlier, common types of position sensors used in hydraulic servo systems include potentiometers, LVDTs (Linear Variable Differential Transformers), magnetostrictive sensors, and encoders. The specific type chosen depends on factors such as required accuracy, environmental conditions, durability, and the specific requirements of the application.
