One very important part of any piece of machinery is the solenoid valve.
Our company, Yuyao No.4 Instrument Factory is a market leader with more than 5 decades of experience in providing specialized production, research and development services for the solenoid valve sector in China.
Our company was first incepted in 1965.
We started producing a variety of solenoid valves for fluid control purposes in 1978.
Our extensive experience and expertise has enabled us to achieve a wide variety of national patents in the field of solenoid valves.
It is notable that our solenoid coil has been awarded both the utility model patent from Germany and the design patent from the European Union, because of exclusive advantages, like: low power consumption, considerable energy savings, built-in modules and one-piece construction.
In addition to this, we are proud to announce that the national safety standard for solenoid valves, GB 30439.6-2014 was drafted by our factory.
Our technical department consists of 10 skilled technicians, 2 electrical engineers and 5 mechanical engineers.
They all have more than 8 years of industry related experience.
The total value of our sales reached 80 million RMB in 2015, which included the value of our exports of nearly 6.2 million USD.
We currently own two registered trademarks.
The “Round Star” is considered an English language version of our trademark.
Yuyao No.4 Instrument Factory was formerly known as a state-owned enterprise, dating back to 1965. These past 5 decades have allowed us to become the leader in providing specialized production, research and development services for the solenoid valve sector in China.
International Sales Department
Backed by a dedicated international sales team, the total value of our sales reached 80 million RMB in 2015, which included the value of our exports of around 6.2 million USD. Our solenoid valves can be found in several dozen countries and regions, including Europe, America and Asia, etc.
Our technical department has deep expertise in the design, research and development of solenoid valves. It consists of 2 electrical engineers, 3 assistant engineers and 5 mechanical engineers. They all have more than 8 years of experience in helping customers design various products.
Our Chairman, Guanjun Liu
Our chairman, Guanjun Liu has researched the solenoid valves for over 3 decades. He started working as a technician as early as 1972. Currently, he is a member of the China Instrument Manufacturers Association and a member of the Solenoid Valve Manufacturers Association. In 2012 he was granted a design patent for the piston of the pilot-operated solenoid valve. This design has been applied in high-pressure solenoid valves and now holds an ultra-large upscale market share. Upholding the philosophy of making energy-efficient solenoid valves, he has developed a built-in integrated coil with the features of low power consumption, considerable energy savings and modular design. This has also enabled him to receive two design patents from China and the European Union.
Our chairman, Guanjun Liu is hosting a technical meeting to discuss the RSPS-25 steam solenoid valve’s structure, advantages as well as the safety precautions in production.
Each year we take an active part in presenting our products at various exhibitions around the world. These exhibitions are held in different places such as Shanghai, Frankfurt, Munich, etc. We look forward to collaborating with customers both at home and abroad.
