Double Eccentric Butterfly Valve with Pneumatic Actuator (BEF)

The valve design is a double eccentric disc tilting mechanism that fits a sealing ring that is rolled or welded into a solid disc seat in a safe manner. An adjustable and removable clamping ring is provided for easy readjustment or replacement of the sealing ring and ensures zero leakage in both flow directions. The result of the perfect design profile and shape of the disc is low head loss. The valve can be closed by a 90-degree clockwise rotating.
This valve is equipped with a pneumatic actuator which is suitable for plants having air compression systems.
