New Rules for Safety Valves in China This Year

The year 2025 is experiencing significant transformations in Safety Valve in China. Regulations have shifted. Manufacturers, auditors and consumers have to change. This blog will overview the new regulations, their meaning, and ways of complying. It will assist any stakeholder interested in safety valves in China to be up to date. These modifications impact on design, certification, installation, inspection and recall.

Why the New Rules Came

A number of accidents with pressure equipment sounded alarm.

Increasing anxiety regarding defective valves and threat to human and civilian lives.

Old standards had loopholes in their regulations that admitted inferior or unsafe safety valves.

China needs greater trustworthiness and reduced breakdowns.

The state is seeking to have a firmer grip on the manufacture and use of safety valves. It also desires to have recall and responsibility in case of failure.

Major Regulatory Changes on Safety Valve in China.

These are the key areas that the new rules address:

Certification Requirements

All safety valves should be able to meet revised national standards (GB standards).

Compulsory certifications which are imposed by the Ministry of Industry or other relevant authorities.

Valves imported should be in accordance or they will be detained.

Design and Manufacturing Standards.

Materials needed to be stronger and to be able to withstand increased pressure and temperatures.

Better mechanisms of sealing to minimize leakages.

Increasing service in negative conditions.

Installation and Maintenance Rules.

Definite instructions of installation written in new standards.

Receiving periodic checks is obligatory.

Maintaining logs and performance testing that would be needed during service.

Recall and Defect Rules

In case a batch of valves has defects that are potentially hazardous, the manufacturers should recall it.

Defect definition is more general: entails design, production, installation or repair defects.

The responsibility lies with the suppliers, importers, installers.

Enforcement and Penalties

The fines, suspension, and market bans became stricter in case of non-compliance.

Production lines can be closed by authorities on the basis of repeat or grave violations.

It will require increased accounting of related accessories and parts.

Effects to Manufacturers and Users.

There are numerous stakeholders who are influenced by these regulatory changes.

The producers will have the need to restructuring testing processes. They should be able to assure that every supplier is up to the new standards. Unnecessary expense and investment in test laboratories probably.

There is a need to enforce longer lead time of certification by the importers. More paperwork required.

The maintenance staff and installers have to observe more rigid inspection timelines. It becomes crucial in terms of record keeping.

The users (industries, plants, construction sites) will be required to ensure that all of the safety valves that are installed are within the new standards. Dispose of old/ non-compliant valves.

The Chinese safety valve compliance steps of Safety Valve.

In order to comply with the new rules, do the following:

Inventory safety valve audit. Determine valves that do not meet new standards.

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.
