Electric Actuated Lined flanged Butterfly Valve

Product Description

Self-controlling PTFE lined butterfly valve is a patented product invented by the company. It belongs to the series of wafer/flange fluorine-lined butterfly valves; it consists of a pneumatic actuator and a fluorine-lined butterfly valve.

Structure matching and combination to form various types of butterfly valve specifications. The product is divided into fully lined butterfly valve and semi-lined butterfly valve according to its lining material. Fully lined butterfly valve due to fluorine lined butterfly valve body cavity

All are lined with anti-corrosion fluoroplastic (PTFE/FEP/PFA). At the same time, the disc and valve stem are lined with fluoroplastic, and there is a silicone rubber gasket on the valve base surface to adjust the valve seat. The base surface is preloaded to achieve sealing performance with the disc.

The valve body adopts a separate type, and the seal at both ends of the valve shaft is controlled by the fluorine rubber ring on the rotating base surface between the butterfly plate and the valve seat, so that the valve shaft does not contact the medium in the cavity and ensures no leakage of the seal. The valve has the advantages of compact structure, small size, reliable operation, good sealing performance, easy maintenance, convenient installation and strong adaptability. It is suitable for any corrosive medium except molten alkali metal and elemental fluorine. It is used for remote centralized control or local control in industrial automatic control systems such as chemical industry, petroleum, medicine, food, steel smelting, papermaking, water and electricity, and environmental assurance. ideal product.

End type:  wafer type, flange type, lug type connection.
