Advantages of Target Hydraulic’s Hydraulic Control Valves
Target Hydraulic’s hydraulic control valve can reduce energy loss by precisely adjusting the flow and pressure of the hydraulic system.
Target Hydraulic’s hydraulic control valve can adjust flow, pressure, and direction with high precision. Its control accuracy can reach the micron level.
Target Hydraulic’s hydraulic control valve can generate system pressure up to 500 bar, and the output torque is 3-5 times higher than that of electric valves.
Target Hydraulic’s hydraulic control valve has a response time as low as 50 milliseconds, more than ten times faster than traditional mechanical valves. This ensures that the system can complete the action in time in an emergency.
Target Hydraulic’s hydraulic control valve adopts an integrated design, which reduces the valve volume by 40%, and uses hardened steel sealing surfaces, greatly prolonging the service life.
Target Hydraulic’s hydraulic control valve has a built-in overflow valve and pressure compensator, which can automatically cut off the oil circuit when overloaded to prevent the system pressure from exceeding the set value.
The modular design of Target Hydraulic’s hydraulic control valve makes it easier to replace the valve core components, shortening the maintenance time by 70%.
Target Hydraulic’s hydraulic control valve uses a special high-temperature resistant coating, allowing it to operate stably in a temperature range of -40℃ to 120℃.
Precise Control Capability
Target Hydraulic’s hydraulic control valve adopts a zero-cover valve core design and high-linear-torque motor, as well as a high-precision displacement sensor, to adjust the valve core position in real time, with a repeatability accuracy of ±0.05%. In addition, its flow resolution is ≤0.01 mL/min, the response time is between 10-15 ms, and the pressure control accuracy is ±0.2 bar, which can be quickly and accurately controlled in a short time.
High Power Density
Target Hydraulic’s hydraulic control valve has made innovations in structure, integrating the multi-way valve into a single piece of forged steel, and the power density can reach 50kW/kg. At the same time, we also use a multi-layer sealing structure, and the working pressure exceeds 700 bar. In addition, its torque output efficiency can reach 98%, which can achieve high power and heavy loads in space-constrained scenarios.

How does a hydraulic control valve work？
The working modes of hydraulic control valves are mainly direction control, pressure control, and flow control.
Direction control: You can change the flow direction of the liquid by controlling the movement direction of the mechanical parts. When the valve core moves to the left, the high-pressure liquid enters the left chamber of the hydraulic cylinder and pushes the piston to the right; when the valve core moves to the right, the liquid flows in the opposite direction and the piston retracts.
Pressure control: To prevent the system pressure from being too high and damaging the equipment, or to maintain a specific pressure, you can set a maximum pressure value. When the pressure exceeds the set value, the valve automatically opens to release the pressure, just like the exhaust valve of a pressure cooker.
Flow control: You can adjust the movement speed of mechanical parts by controlling the oil flow. Limit the flow by enlarging or shrinking the liquid channel. The wider the channel, the faster the flow rate.The narrower the channel, the slower the flow rate.
The main functions of directional control valve in a hydraulic system are: switching the direction of the oil circuit, starting or stopping fluid flow, and coordinating the joint operation between multiple oil circuits.
To adjust the hydraulic flow control valve, you first need to turn off the power supply of the hydraulic pump, release the residual pressure, confirm that the pressure gauge shows 0 bar, find the adjustment mechanism of the flow valve, and confirm the adjustment direction mark. Then use an open-end wrench to loosen the lock nut counterclockwise so that the adjustment knob can rotate freely. If you need to increase the flow, slowly turn the adjustment knob counterclockwise. If you need to reduce the flow, slowly turn the adjustment knob clockwise. Do not turn more than 15° each time to finely control the flow rate. After completing the adjustment, keep the knob in position and tighten the lock nut clockwise to 40-50 N·m torque. Finally, restart the system and observe the operating speed of the actuator. If it is too fast, reduce the flow again. If it is too slow, increase the flow.
First, you need to relieve the hydraulic pump to release the residual pressure. For hydraulic valves with dedicated exhaust valves, you can use an Allen wrench to loosen the exhaust screw 1-2 turns counterclockwise, then briefly start the hydraulic pump to allow the oil to seep out from the exhaust port. When there are no bubbles in the oil seepage, immediately turn off the pump and tighten the exhaust screw to the specified torque. For hydraulic valves without dedicated exhaust devices, you can manually operate the hydraulic cylinder to reciprocate 5-10 times through the full stroke to force the air back into the tank. Then loosen the joint at the highest point of the pipeline, slowly start the pump until the oil flows out continuously without bubbles, and then lock it.
