Jester High Silicon Cast Iron Ball Valve Q41G-16Si Corrosion-resistant Erosion-resistant Seawater Valve Direct from Manufacturer

Fujian Just Valve Manufacturing Co., Ltd. is a high-tech enterprise engaged in the production of valves for super strong acid, medium strong acid, weak acid, and special harsh media such as ash, slurry, and slag, as well as conventional media. Its headquarters is located at No. 83, Siming Industrial Park, Tong'an District, Xiamen City. The company was established in 1991, has more than 10,000 square meters of production plants, has a large-diameter valve body casting supporting factory and a vacuum consumable arc skull melting furnace, and can cast and forge a series of products of carbon steel, stainless steel, duplex steel, titanium, titanium alloy, tungsten, molybdenum, tantalum, niobium, hafnium, zirconium, nickel alloy, etc. There are more than 300 employees currently. 

After 30 years of development, Jest Valve now has 38 patented products such as the rapid rotary valve, the combined valve for transporting ash slurry and slag, the new technology self-equipped ice-breaking bottom valve of the tank, the Antel energy-saving valve, the acid-resistant nano new technology pipeline, the new type sight glass, the new type high-performance butterfly valve, the new type high-temperature and high-pressure power station valve, etc., as well as more than 1,500 types and over 6,000 model series of various gate valves, globe valves, check valves, ball valves and butterfly valves. Among them, the total sales volume of special material valves with independent intellectual property rights (titanium valves, nickel valves, zirconium valves, tantalum valves, Hastelloy alloy valves, Monel alloy valves, etc.), special structure valves and acid-resistant, corrosion-resistant, erosion-resistant and wear-resistant valves ranks first in China. 

The acid-resistant high-silicon cast iron valves produced by Jest can withstand corrosive media except (HF). After continuous technological innovation and optimization of the acid-resistant high-silicon cast iron valve material, the pressure bearing and temperature resistance have been greatly improved. The medium pressure resistance can reach 25 Kg, the acid-resistant temperature can meet the normal use at 150℃, and the instantaneous temperature can reach 180℃. 

Acid-resistant high-silicon cast iron valves can be widely used in corrosive media except (HF) and in marine engineering, seawater desalination treatment, seawater cooling circulating water of power plants in coastal cities, etc. 

Acid-resistant high-silicon cast iron material valves belong to a kind of long-life material valves. As long as the installation, operation and usage processes and methods are correct, the usage cost of the valves can be very low. 

Due to the particularity of the high-silicon material, its deficiency is that it is afraid of being hit or knocked by gravity.
