1. Regular Inspection of Appearance and Internal Components  

Regularly inspect the valve body for cracks, corrosion, or leakage. Check whether the fastening bolts are loose and whether the pressure gauge is functioning properly. After shutting down and relieving pressure, disassemble the valve and inspect components such as the valve core, valve seat, diaphragm, and spring for wear or aging. If any issues are found, replace with original parts or send for repair promptly. Do not operate the valve with existing faults.The main pressure reducing valve product names of China Pressure Reducing Valve Network include:Internal Thread Bigger diaphragm-Type HighSensitivity Reducing Valve,Internal Thread Pressure Reducing And Maintaining Valve For WaterInternal Thread Corrugated Pipe Reducing Valve,Lever-Type Steam Reducing Valve,Piston Adjustable Reducing And Stabilized Valve,Self-regulative ValveTunable Pressure-reducing-and-maintaining Valve

2. Internal Cleaning and Lubrication   Pressure relief valve Suppliers

After disassembly, thoroughly clean the interior of the valve body to remove dirt, rust, and debris. Pay special attention to cleaning the valve port, diaphragm chamber, and strainer. Use a cleaning agent compatible with the medium to avoid damaging the sealing components. After cleaning, apply an appropriate amount of specialized lubricating grease to moving parts such as the adjusting screw and valve stem to ensure smooth and reliable operation.

3. Strict Adherence to Maintenance Intervals   Pressure relief valveStandard

Follow the maintenance intervals specified by the manufacturer, typically every 3 to 6 months. Avoid both long-term neglect, which can lead to debris accumulation and seal aging, and excessive disassembly, which may cause thread wear or assembly errors that affect service life. Keep maintenance records after each service.

4. System-Level Inspection and Protection  

Inspect the piping and vessel surfaces for rust, weld slag, or other contaminants that could enter and damage the valve. It is recommended to install a strainer upstream of the pressure reducing valve and clean it regularly. Additionally, check the system for abnormal conditions such as vibration or water hammer to ensure the valve operates in a stable environment.
