How to Maintain and Maintain Screw-in Cartridge Valves

Screw-in cartridge valves are common control valves in hydraulic and pneumatic systems, and their proper operation is critical to overall system performance and efficiency. Therefore, regular maintenance and maintenance is very necessary. Let's introduce some maintenance and maintenance methods of threaded cartridge valves.

Regular cleaning and lubrication

Regular cleaning and lubrication of screw-in cartridge valves is the basis for maintenance and maintenance. During use, screw-in cartridge valves are subject to deposits, dirt and oxides which can interfere with proper valve operation. Therefore, it is necessary to clean and lubricate the threaded cartridge valve regularly. During the cleaning process, use a special cleaning agent to thoroughly clean the internal and external surfaces of the valve. For lubrication, use suitable lubricating oil to prevent the valve from being damaged due to excessive friction.

Check for tightness

Sealing is the key to the normal operation of screw-in cartridge valves. Therefore, it is very important to check the tightness of the valve regularly. During the inspection process, pay attention to check whether the gasket of the valve is intact, and check whether the sealing surface of the valve is flat and whether there are scratches and damages. If the inspection finds a problem, it is necessary to replace the gasket or repair the sealing surface in time.

Check springs and shrapnel

The spring and shrapnel of the screw-in cartridge valve are the key components to control the valve switch. Therefore, it is also very important to regularly check the condition of these components. During the inspection process, pay attention to check whether the spring and shrapnel are deformed or damaged. If there is a problem, these components need to be replaced in time.

Check valve solenoid

If the screw-in cartridge valve has an electromagnet, it is also necessary to check the condition of the electromagnet regularly. During the inspection process, pay attention to check whether the circuit of the electromagnet is normal, whether there is an open circuit or short circuit, and also check whether the magnet of the electromagnet is strong enough, whether there is damage and wear. If there is a problem, the electromagnet needs to be replaced in time.
