Specialized Butterfly Valve Manufacturing Supplier

EATHU to higher than the international and domestic standards and customer requirements, the establishment of internal quality assurance system, the implementation of a comprehensive, the whole process of quality control, EATHU's quality control centre, can independently and independently from the product prototype testing and certification to the final factory inspection of all the inspection, testing; these inspections, inspections, including: ray flaw detection, colouring flaw detection, magnetic particle testing, ultrasonic flaw detection, spectral analysis, Material identification (PMI), metallurgical organisation testing, a variety of mechanical properties test, fire test, ultra-low temperature test, high temperature test, vacuum test, low leakage test, high-pressure gas test, hydrodynamic test, product life test, as well as a series of valve experiments, such as conventional hydraulic pressure. In order to ensure the quality of blanks EATHU has its own casting factory, from raw material production to the finished product out of the warehouse to effectively control each process, to achieve continuous improvement in process control and management capabilities.

In order to ensure the quality of butterfly valve, butterfly valve products need to meet the appropriate standards and requirements. The following are EATHU quality control standards.

1. Appearance inspection: valve surface finish, no obvious defects, clear signs, etc..

2. Size and tolerance test: valve connection size, sealing surface clearance, etc..

3. Pressure test: Butterfly valve pressure test to ensure that it can withstand normal working pressure.

4. Sealing performance test: the butterfly valve sealing performance test, such as leakage test, sealing ring corrosion resistance test.

EATHU has established a perfect product traceability system, with detailed production records and inspection reports for each batch of products for verification and traceability.

EATHU has a perfect customer feedback management system, regularly analyses and collates customer feedback and takes timely measures to solve problems in order to improve product quality and customer satisfaction.

Butterfly valve is the most widely used kind of valve at present.

Butterfly valve valve plate in the opening and closing movement, the butterfly plate and the valve seat with wiping between, so the butterfly valve can be used in the flow medium pipeline with suspended solid particles, according to the strength of the seals. Can also be used in powder and granular flow media pipeline.

Butterfly valve structure length and overall height are not large, opening and closing speed is very fast, when the butterfly valve in the fully open, the valve body is only the butterfly plate is the only resistance to the flow of media, so the butterfly valve fluid resistance is also very small, when the butterfly plate opens to about 15 ° to 70 °, and can be sensitive flow control, so based on the structural principle of the butterfly valve, butterfly valve is the most suitable for the production of large calibre valves.

Specifically, the butterfly valve is suitable for the following occasions.

1. Requirements for throttling, regulating and controlling the flow of the pipeline.

2. Slurry media and solid particles in the working environment of the media.

3. Requirements of the valve structure of short length of the occasion.

3. Requirements for fast opening and closing speed of the occasion.

3. The occasion of small pressure difference.

When there are the following working conditions, can also choose butterfly valve.

1. In the two-position adjustment, shrink the channel, low noise, cavitation and cavitation phenomenon, a small amount of leakage to the atmosphere, abrasive media, you can choose butterfly valve.

2. In special working conditions, throttling adjustment or strict sealing requirements, or severe wear and tear, low temperature and other working conditions require the use of metal sealing band three eccentric or double eccentric special butterfly valves.

The above is the butterfly valve applicable occasions and the application of working conditions, I hope to be able to help you in the use of butterfly valves above.
