Product Description:
The advantages and features of SUN cartridge valves include:
Large flow and low pressure loss: SUN cartridge valves have large flow capacity and low pressure loss, and are suitable for large flow hydraulic systems.
Sensitive action: The main valve core has a short stroke, sensitive action, fast response, and small impact.
Strong oil resistance: There is no strict requirement for oil filtration accuracy, and it has strong oil resistance.
Simple structure: The valve core has a simple structure, good sealing, and a single but reliable function.
Easy to install and maintain: The floating design reduces the sensitivity to installation torque, avoids the possibility of internal moving components getting stuck, and is easy to install and maintain.
High pressure regulation accuracy: High pressure regulation accuracy, small pressure fluctuations with flow, smooth regulation, and low noise.
High cost-effectiveness: Mass production has significant benefits for users, reducing manufacturing hours and the generation of system pollutants.
Precautions for use include:
Preparation before installation: Check the size and roughness of the socket, remove the edges and burrs, and ensure concentricity; check the model and sealing ring of each component, disassemble and clean, replace and perform performance tests if necessary; clean the components of the valve block.
Installation method: Apply grease or engine oil to the socket and the outer ring of the plug assembly, knock it in with a rubber hammer or press it into the socket with the cover screw, fix the control cover with the hexagon socket screw, and then install the pilot control valve.
Common problems and solutions:
Air leakage: Check whether the valve body, valve core and seal are damaged or worn, replace damaged parts and ensure that the connection is tight.
Valve core stuck: Spray lubricating oil on the valve core to make it slide freely; if the problem persists, you may need to replace a new valve core.
Valve cannot be closed or opened: Check whether there is debris blocking the inside of the valve, clean and remove the debris; if the problem persists, you may need to replace parts or the entire cartridge valve.
Excessive temperature problem: Choose valves made of high temperature resistant materials and ensure the appropriate temperature range for the medium.
Noise problem: Choose valves with noise reduction design or install sound-absorbing materials around the valve to reduce noise.
