Check valve:
1. ISO: 9001/2000, CE, RoHS, CQC
2. Check the backflow
3. Copper
DZ 4"/6" this model of solenoid valve achieves the check- valve effectiveness via the fluid pressure. It can avoid the drawback impacts of parts fatigue and impurity such as furring in traditional spring check valves and mechanical check valves. There is no pressure loss on the front side. The check-valve effectiveness is safe and reliable.
Operational pressure: 0--0.8Mpa
Media temperature: 1 ° C--130 ° C
Connection type: 15/20 external screw thread
Hangzhou Xiangjun Electronics Co., Ltd., with the predecessor of Xiangjun Electronic and Electrical Appliances Factory, is a domestic professional electric electromagnetic valve manufacturer with independent research and development capabilities. Our company currently has production lines including mould R&D and manufacture equipment, injection molding formating processing, electrically operated valve (EOV) assembling lines, and product testing equipment. At the same time, our company has a number of patented technologies of solenoid valves. Our products are widely used in the automation areas, such as automatic control systems for solar water heaters, automatic controlled scavenger systems, irrigation systems, and automatic fluid (volume) billing systems. We have been conducting effective cooperation with major enterprises in the above mentioned areas in terms of new product research and development.
We insist on the principle of "cherishing talented people, establishing brands and running business honestly", at the same time holding the idea of doing everything sicerely. We strictly conduct product quality control with the philosophy of "quality and detail oriented". In 2005, our major products were certified by China Quality Certification Center. In order to expand overseas markets, we attained RoHS European Environmental Protection Certification and the USA CE Electrical Appliance Performance Certification in November 2007. In the early of 2008, we obtained the ISO9001: 2000 Quality Management Certification. We have been continuously developing distinguished products with delicate appearance, remarkable quality and performance, in the basis of patented technologies (patent number: ZL03207284.8&ZL03263467.6). Our company has become one of the expert performers and industry leaders in the area, and has won tons of praises from our customers. With powerful technologies and proprietary intellectual property and patent technologies, we ensure the stability of our solar watering valves, and provide the necessary condition for the popularization of automatic watering monitors for solar water heaters.
Currently, it is the fact that our competitors are still quite unaware of the importance of proprietary brands and the intellectual properties in the domestic industry of solenoid valves. However, we will annually invest 5% of company revenue to our R&D department for solenoid valve product development. Now, although facing the international financial crisis, our company is marching to the international markets under the premise of excellent operation in domestic market. We are shooting for catching up with advanced international counterparts, in order to contribute our efforts to automation industry in both China and all over the world.
Our company has been recognized as a high-tech high-growth innovative enterprise in the city of Hangzhou (2010; Eagle Project) and the province of Zhejiang (2011).
It is our honor to introduce our company to you. We warmly welcome you to give us telegrams, mails, or calls for any cooperation discussion.
