Butterfly valve type 240 ABS
DA (Double acting)
Without manual override

The type 240 series pneumatically actuated wafer style butterfly valve from GF Piping Systems is the ultimate choice for the high demands of the industrial world. The unique double eccentric design means the disc is not in contact with the seal in the open position. The result is less wear and operating torques that are half that of our previous model. Better chemical compatibility is achieved because the inner body is the same material as the pipe.

The unique o-ring design insures a superior seal with virtually any type of flange without the need for additional gaskets. Additionally, the electro-pneumatic positioner, stroke limiter, and feed back switches give flexibility for integration into a wide variety of applications.

  • Control range 90°<)
