CLASS 150-300LB Pneumatic Flanged Butterfly Valve

This sort of pneumatic flanged butterfly valve consists of multi-layer metal sitting down butterfly valve and pneumatic actuator. This pneumatic actuated flanged butterfly valve may change pressure, flow, temperature, liquid level along with other parameters. The pneumatic metal sitting down butterfly valve has the benefits of compact structure, strong function, small volume, good sealing performance, reliable performance, simple matching, large circulation capacity, which is particularly appropriate for that occasion the medium is viscous, that contains particles and fiber qualities. At the moment, the pneumatic flanged butterfly valve is broadly utilized in industrial automatic control systems of food, ecological protection, light industry, oil, papermaking, chemical, teaching and research equipment, electrical power along with other industries.

The Characteristics of Pneumatic Flanged Butterfly Valve:

1. The valve adopts a three-eccentric sealing structure, and the valve seat and the butterfly plate have almost no wear, and have a tighter sealing function.
2. The sealing ring is made of stainless steel. It has the double advantages of hard metal sealing and elastic sealing. It has excellent sealing performance in both low temperature and high temperature conditions, and has corrosion resistance and long service life.
3. The large-size butterfly plate adopts a truss structure with high strength, large flow area and small flow resistance.
4. The valve has a two-way sealing function. It is not restricted by the flow direction of the medium during installation, and is not affected by the spatial position. The pneumatic actuated flanged butterfly valve can be installed in any direction.
5. The drive unit can be installed in multiple stations (rotated 90° or 180°) for user convenience.
