Common Problems with China’s Safety Valves and How to Fix Them

The safety valves are very important in the integrity and safety of pressure system of industries like oil & gas, manufacturing as well as the power generation facilities. They may, however, like any other mechanical part, have problems. It is important to learn about some of the frequent issues and the solution to such issues- particularly in sourcing a Safety Valve in China.

This blog will discuss some of the common problems that are associated with safety valves and how to either troubleshoot or avoid them.

Why Quality Matters in Safety Valves

Safety valves are pressure-relieving devices that are used when there is an overload of pressure that causes pressure release automatically. Failure to install good quality valves or install the valves properly may cause it to break, which may endanger the equipment and people. Choosing a manufacturer of Safety Valve in China is important to make sure it is highly precise in engineering and certifies the international safety standards.

1. Leakage at the Valve Seat

Problem:

Leakage between the valve seat is one of the most widespread problems and it typically occurs due to the dirt, corrosion, and misuse of the closing pressure.

Solution:

Take the valve apart and clean it. When the seat is damaged it may have to be lapped or replaced. After installation, always make sure that valve is in a clean atmosphere and it is also closed using proper torque settings.

2. Valve Fails to Open at Set Pressure

Problem:

What will happen is that when a safety valve fails to open at its assigned operating set pressure then it destroys its own purpose. This may occur during the wrong calibration, spring breakage or mechanical jamming.

Solution:

The valve should be tested on a regular basis and adjusted to manufacturer recommendations. Correct defective springs, to lubricate moving parts to prevent jamming. Reliable suppliers of the Safety Valve in China also provide recalibration services and maintenance suggestions.

3. Chattering or Vibrations

Problem:

Chattering occurs when a valve opens and closes very fast which is noisy and the risk of damage. Most of the time it is caused because of extra large valves, or pressure change.

Solution:

Check that the size of valve must be same with the flow rate of the system. A vibration and noise can be reduced by installing dampeners or pulsation absorbers. Such mismatches can be avoided by consulting an authority supplier of Safety Valve in China in the process of selection.

4. Corrosion and Material Failure

Problem:

Corrosion may occur due to exposure to violent media or hostile surroundings resulting in leakage and structural collapse.

Solution:

Make valves of corrosion resistant materials such as stainless steel. Most manufactures of high quality Safety Valve in China also offer ranges that are applicable in cases involving corrosion and also certifications of the material utilized.

Final Thoughts

Plant and personnel safety where safety valves play a major role cannot be left without attention as even slight cases can result in serious effects. Systems should be kept efficient and safe through regular inspection, proper mounting of systems and high quality components used.

When you are using a Safety Valve found in China, it will be best to choose a good manufacturer and this time it is PV Valve, who will provide you the high-performance, complete compliance and excellent support.
