Imported pneumatic hard seal butterfly valve Imported metal seal butterfly valve Robert brand

Imported pneumatic hard-seal butterfly valve (Germany Robert brand)
Product Overview
The structure of the German Robert imported pneumatic hard-seal butterfly valve is designed using the three-dimensional core braiding principle, and the valve seat adopts a multi-layered structure compatible with hard seals. Exquisite processing and advanced technology. The valve adopts a triple eccentric structure, which optimizes the spatial motion trajectory of the sealing surface. There is no friction or interference between the sealing surfaces. In addition, the sealing material is properly selected, so that the sealing performance, corrosion resistance, high temperature resistance and Wear resistance, etc. are reliably guaranteed.
Product Features
This valve adopts a three-eccentric sealing structure, with almost no wear on the valve seat and butterfly plate, and has a tighter sealing function
The sealing ring is made of stainless steel and has metal hardness. It has the dual advantages of sealing and elastic sealing. It has excellent sealing performance at both low and high temperatures, and has the characteristics of corrosion resistance and long service life
. The sealing surface of the disc is made of surfacing cobalt-based carbide. , The sealing surface is wear-resistant and has a long service life
The large-sized butterfly plate adopts a quilted frame structure, which has high strength, large flow area and small flow resistance.
. This valve has a two-way sealing function. It is not restricted by the flow direction of the medium or affected by the spatial position during installation. It can be installed in any direction
. The driving device can be installed in multiple positions (rotation or). , convenient for users to use.
