Design And Production of DN600 Ball Check Valve

Our company has successfully designed the mold for the DN600 spherical check valve, and the mold is being produced! This means that our company will be able to produce larger size ball check valves to meet market demand.




Application field of open rod elastic seat seal gate valve

Open rod elastic seat seal gate valve is the replacement product of traditional gate valve, using the elastic gate plate to produce micro deformation compensation, to achieve good sealing effect, the valve has the advantages of light switch, reliable seal, good elastic memory and long service life, and can be widely used in tap water, sewage, construction, food, electric power, medicine, metallurgy, light textile, etc.




German standard check valve manufacturer: for your brief introduction of German standard check valve

The standard check valve is a self-sealing valve that relies on the flow of media to automatically open and close the disc, thus effectively preventing media backflow. The product has reasonable structure, reliable sealing, excellent performance and beautiful appearance. The German standard check valve automatically opens and closes through the force generated by the medium itself flowing in the pipeline, which is an automatic valve.




Hebei Huahui Valve Co., LTD. : Introduce the information of German standard check valve

German standard check valve is suitable for nominal pressure of PN1.6-4.0MPa, working temperature of -20-℃-350℃, such as petroleum, chemical, pharmaceutical, chemical fertilizer, power industry and other occasions to cut off or connect the pipeline, German standard check valve main structural characteristics:




Hebei Huahui Valve Co., LTD. : To introduce the performance characteristics of German standard gate valve

Not easy to break. In the past, traditional cast iron soft seal German-standard gate valves were often damaged due to foreign body impact, collision or overlap. This has been greatly reduced by the use of ductile iron in soft seal German gate valves.




Ball check valve manufacturer: Take you to understand the ball check valve information

Ball check valve is a multi-ball, multi-channel, multi-cone backflow structure of the check valve. It is mainly composed of front and rear valve bodies, rubber balls and cones.




Soft seal gate valve manufacturer: What are the characteristics of soft seal gate valve

Soft seal gate valve can be used in chemical industry, petroleum, sewage treatment, urban water supply and drainage and many other fields. It is used in a strictly sealed environment under normal temperature and pressure.




Large caliber gate valve manufacturer: the working principle of large caliber gate valve

Large diameter gate valves are used to cut off or connect the medium in the pipeline through wedge gate valves and parallel gate valves. According to the sealing surface configuration, it can be divided into wedge gate valve and parallel gate valve. Wedge gate valve can be divided into: single gate, double gate and elastic gate. Parallel gate valves can be divided into single gate and double gate. There are two kinds according to the thread position of the stem: open gate valve and dark gate valve.




Underground gate valve manufacturer: For you to introduce the underground gate valve related information

Underground gate valve and small purpose valve using rubber integral package to produce deformation compensation, so as to achieve good sealing effect, overcome the ordinary gate valve seal poor, water leakage and rust problems, and more effectively save the installation space. It can be widely used as water, sewage, construction, petroleum, chemical, food, medicine, textile, electric power, Marine, metallurgical and energy systems on the flow control and interception device.
