Concentric butterfly valve with bonded vulcanized rubber linings

A butterfly valve is a shut-off valve with a relatively simple construction.  It is defined as a valve in which the obturator rotates about an axis at right angles to the direction of flow and, in the open position flow passes around the obturator. While in the closed position, the disc blocks the valve bore while in open position, the disc is turned to allow flow. A quarter turn takes the valve from fully open to the fully closed position or the opposite, and thus the butterfly valve allows for quick opening and closure.

Concentric butterfly valve

These valves are suitable for use in a broad range of applications within water supply, wastewater treatment, fire protection, and gas supply, in the chemical and oil industries, in fuel handling systems, power generation, etc. It gives out advantages like taking up lesser space due to its simple construction, and the lightweight and lower cost compared to other valve designs. Concentric butterfly valve with bonded vulcanized rubber linings features a seating concept. The rubber is injection molded directly on the valve body forming a permanent bond. Consequently, there is also no risk of deformation or dislocation of the liner making the valves suitable under vacuum condition. The combination of the profiled disc edge and the excellent rubber quality ensures the maximum durability of the liner.
