Desulfurization ceramic valve Xi'an electric ceramic ball valve Fadeng Shaanxi office

It is necessary to use ceramic gate valves under extremely harsh conditions in coal gasification equipment, where the high-temperature and high-pressure gas contains hard particle corrosive gas streams of coal powder and ash powder. In the past, valves made of metal with cobalt chromium tungsten hard alloy deposited on the sealing surface could not meet the requirements for use. Nowadays, metal is used for the high-temperature and pressure resistant parts of the shell, while ceramic is used for the sealing parts. German VATTEN valve provides you with high-quality productsShandong electric ceramic ball valve for desulfurization ceramic valveNot just a change!

Shandong electric ceramic ball valve for desulfurization ceramic valve：

1. All parts in contact with the medium are structural ceramic materials, with chemical stability and hardness * (Rockwell hardness HRC90) second only to diamond. Therefore, this valve has excellent wear resistance, corrosion resistance, and erosion resistance, as well as good insulation and low thermal expansion.

2. The sphere is manufactured using grinding equipment and processes, with high roundness accuracy and good surface quality. After being ground against the valve seat, it can achieve good sealing performance by utilizing the self lubrication of Zr02 ceramic.

3. Changed the disadvantages of metal hard sealed ball valves, such as easy leakage, high torque, and poor corrosion resistance of sealing surfaces.

4. The excellent wear resistance of ceramics makes this valve durable and reliable. Long service life, 2-4 times longer than titanium alloy valves and Monel valves.

5. This valve has the advantage of being suitable for high hardness granular media or media with soft particles but corrosion, and is currently the most suitable valve for such media.

Valve body: WCB, SS304, SS301, SS316, SS201, ductile iron

Ceramic lining: Alumina/Zirconia/Silicone Carbide

Ball core valve seat: Zirconia/Silicone Nitrate

Valve stem: 316/316L stainless steel, HC alloy, Monel alloy, structural ceramic.

Ceramic diaphragm valve

The structure of the valve is very simple, and its contact area with the medium is composed of a ceramic valve body and a PTFE diaphragm.

After precision grinding and polishing treatment, the ceramic valve seat surface will not leak when pressed by the diaphragm. As a supporting material in the rubber village, fluororubber is used.

The channel of the ceramic valve body has a smooth surface and minimal friction with the medium.

Ceramic plug valve

Ceramic plug valve consists of a ceramic valve body and a plug, with sealing components made of Teflon. It is a straight through valve with low flow resistance.

The contact medium of the valve is a single ceramic component added to the interior, which will not deform under high temperature, high vacuum, or under the action of permeable drugs,The valve seat position generates necessary sealing pressure due to the wedging force of the ceramic plug valve.
