Product Description:
The characteristics and advantages of proportional relief valves mainly include the following aspects:
High-precision control: The proportional relief valve uses advanced proportional solenoids as electrical-mechanical conversion elements, which can continuously and proportionally convert the input electrical signal into mechanical force and displacement output, and realize precise control of the pressure, flow and direction of the hydraulic system. Compared with traditional switch-type hydraulic valves, proportional valves have higher control accuracy and more stable performance.
Continuously adjustable: The valve core opening of the proportional relief valve can be continuously adjusted according to the input electrical signal, avoiding the impact phenomenon when the normally open switch-type gas valve is switched, and can realize stepless adjustment of pressure and speed.
Remote control and energy saving and environmental protection: The proportional relief valve can realize remote control and program control, simplify the system, reduce components, use less power, generate less heat, and have low noise. It will not cause fire and pollute the environment. It is less affected by temperature changes.
Multiple functions: The proportional relief valve has multiple functions in actual applications, such as constant pressure relief, pressure stabilization, system unloading and safety protection. It can maintain the stability of system pressure in the quantitative pump throttling regulation system to prevent system overload; generate back pressure on the return oil line to increase the stability of moving parts; control the unloading of the hydraulic pump through the remote control port; and perform overload protection when the system pressure exceeds the set pressure.
Precautions when using the proportional relief valve include:
Choose a suitable proportional solenoid: The thrust of the proportional solenoid is certain, and different pressure levels require changing the aperture of the valve seat to obtain, so it is very important to choose a suitable proportional solenoid and valve seat aperture.
Maintenance and care: Regularly check the working status of the proportional relief valve to ensure its normal operation. Pay attention to cleaning and maintenance to prevent impurities from entering the valve body and affecting its performance.
Prevent overload: During use, pay attention to the load changes of the system to prevent damage to the valve due to overload. Regularly check the pressure and flow of the system to ensure operation within a safe range.
Through the above introduction, you can better understand the characteristics, advantages and precautions of the proportional relief valve when using it to ensure its effective application in the hydraulic system.
