New excellent valve product – Semi-ball valve

Semi ball valves have the characteristics of small opening force, good sealing performance, etc. Hemispherical valves are widely used in two-phase media such as water, steam, sewage, petrochemical industry, natural gas, solution and slurry, as well as ideal transmission equipment for dust and gas, because of their wear-resistant and corrosion-resistant materials.


When storing semi ball valves for a long time, regular inspection should be carried out to keep the surface area runner clean, remove dirt, and coat with preservatives to keep them in a semi-open state. Continue reading “New excellent valve product – Semi-ball valve”

Promoting Green Casting is the Development Trend of Valve Casting Industry in the Future

At present, people have very high quality requirements for precision valve steel castings, so during the process , valve manufacturers also pay great attention to the selection of process methods and production processes, so as to ensure that the production of steel castings can reach higher application standards. First of all, we should be more cautious when choosing raw materials. Although many steel castings do not have much difference in appearance, due to the different selection of raw materials, there will be differences in quality and service life of steel castings in the process of using, so the selection method of raw materials needs special attention.

Making a correct and reasonable production process is the key to reduce the cost of resin sand casting valve. Whether it is reasonable or not directly affects the yield, quality and cost of castings.

Extension long stem concentric butterfly valve for Germany plant

The purpose of extension long stem for valve mainly for three reason: Low temp. medium , High temp. medium, Remote operation. 1. Low temp. medium, to reduce heat transportation, keep neck packing warm enough. so long stem was adopted. 2. High temp. medium, to have better heat radiation,to keep neck packing cool enough and also easy for operator touch, extension was considered. 3. Remote control, to enable operator control valve far from pipe valve, extension can also be used.

The market competitiveness of cast iron valves is further reduced?

With the acceleration of urbanization in China, domestic sewage treatment and municipal treatment facilities will also be developed on a large scale. As a necessary pipe and valve, it will welcome a broad market prospects.

Thanks to the strong support of the government, the production and application of plastic pipes in China has really begun to develop rapidly, and cast iron pipes have been replaced in some fields, such as: sanitary ware water tank fittings with water intake below water level (low water intake); leakage with water seal less than 5 cm, which is prohibited in all new construction projects and maintenance projects; cast iron drainage pipes with common sockets (manual sand turning rigid joint) Cast Iron Drainage Pipe; Galvanized Iron Sheet Outdoor Rainwater Pipe; Spiral Lifting Cast Iron Nozzle; Cast Iron Globe Valve. It is not allowed to be used in indoor parts of residential projects. Continue reading “The market competitiveness of cast iron valves is further reduced?”
