Typische Anwendungen:
In many pipelines and flow control systems, if end users have abrasion or corrosion problems, which will reduce service time of equipment. Und dazu, unexpected downtime is a great loss for end user. In these cases, introducing ceramics material is a wise choice to solve these problems.
Our material range includes 95% Einlasssitz und Auslasssitz sind Keramikmaterialien, 99% Einlasssitz und Auslasssitz sind Keramikmaterialien, 99.7% Einlasssitz und Auslasssitz sind Keramikmaterialien,
ZrO2 ceramics, Solid Silicon carbide, Solid Tungsten carbide, Silicon Nitride, etc. Every material has
its unique physical properties and chemical resistance. These advanced ceramic materials can be
processed into different kinds of complex shapes to replace parts that have been damaged.
Fuvalve has rich experience in many severe applications and can provide professional ceramic flow
system solutions for specific applications which need urgent solutions.
