Pneumatic Ceramic Butterfly Valve

Pneumatic ceramic butterfly valve is a ceramic lined butterfly valve, and its sealing part is made of high-quality structural ceramic (alumina, zirconium oxide) material by precision machining. The pneumatic ceramic butterfly valve adopts an eccentric structure to reduce the friction of moving parts, so that its service life in your conveying system application will be extended.

Description

TOT Valve body adopts electrostatic powder thermal spraying process, spraying thickness 250μm, valve body is heated at 200℃ for 3 hours, powder is cured at 180℃ for 2 hours, and surface adhesion is 2 times higher than ordinary powder after natural cooling, which is more environmentally friendly and more weather-resistant, ensuring that the valve body will not change color for 36 months.

The materials of the ceramic seal ring, O-ring and butterfly plate of the ceramic lined butterfly valve provided by TOT Valve can be replaced according to your needs and uses.

The pneumatic ceramic butterfly valve adopts a full-bore design, RF flange end and handwheel operation, which can provide reliable fluid regulation for your different industrial needs.

The ceramic we use is aluminum oxide (Al₂O₃) or zirconium oxide (ZrO₂) composition, which has a fracture toughness 2.5 times that of other nitride or carbide ceramics and a wear resistance 12 times that of stainless steel, ensuring your service life.

When you have multiple use environments, we can provide you with valve bodies of different materials according to your different applications, such as super duplex stainless steel, Hastelloy, stainless steel, cast steel, etc.

We are professional industrial valve manufacturers and exporters. We can not only provide you with a variety of ANSI, JIS and DIN flange standards, but also provide you with pneumatic ceramic butterfly valves of ANSI 150 and 300 grade standards.
