INTRODUCTION
Parameter:
Electric three-eccentric metal hard seal butterfly valve is mainly used for drainage of water plants, power plants, steel smelting, chemical industry, water source engineering, environmental facility construction, etc is mainly used for drainage of water el plants smelting, power , chemical industry, water source engineering, environmental facility construction, etc., especially suitable for water pipelines, as regulating and intercepting equipment. Compared with the centerline butterfly valve, the double eccentric butterfly valve is more resistant to high pressure and good stability. Compared with other valves, the larger the caliber, the lighter the material, and the lower the cost.

Features
1.Protection of gearbox IP 68-8 (submersion up to 8 m of water) and actuator IP 68 (submersion up to 8 m of water, during 96 hours and 10operations)

①With position indicator.

②Clockwise Close (CC).

③For installation above ground and in non-flooded chambers.

④Designed and tested to an endurance level of 2500 cycles minimum, inaccordance with EN 1074-1 and 2.

⑤Supplied with a handwheel.

the

2.Reduces resilient seal’s wear and tear ensuring detachment from the body seat ring the moment the valve begins to open.

①reduces pressure loss in fully open position by the disc

②parking in a zone of reduced flow.

③lower torque requirement to rotate the disc leads to less

④wear and longer life of the gasket and other elements.
