The double flanged concentric soft sealing rubber lined butterfly valve D341X integrates some advantages of eccentric flanged butterfly valve and concentric wafer butterfly valve, filling a blank between eccentric flanged butterfly valve and centric wafer butterfly valve. The flow part of the valve body cavity is designed with vulcanized rubber, and the valve seat is combined as a whole with good sealing performance. It can be widely used in water, agricultural, municipal and other fields.

PRODUCT FEATURES

Adopt the optimized plate shaft pin free connection, effectively avoid the hidden danger of plate shaft cone pin connection leakage, and facilitate the replacement of parts on site.

The valve is lined with rubber, and the rubber is vulcanized directly on the body as the injection to ensure the permanent adhesion. The use of the adhesive layer will enhance the reliability of the Disai butterfly valve.

90° opening and closing, worm gear drive, small operating torque

The optimized lining design and molding process can achieve perfect lining and internal sealing of valve body, and ensure the perfect realization of valve plate seal and overall flange gasket seal.

Bidirectional sealing, excellent performance, superior parts processing performance

Valve plate and seat through the overall spherical seal, valve plate and seat contact more reasonable, ensure valve plate seal, reduce valve torque. The double shaft design of the valve can effectively reduce the pressure loss of the valve and reduce the flow resistance.

Various sealing materials are available for users to choose

The valve shaft and valve body can be precisely connected with the valve plate by increasing the design structure of the bushing, and the self-lubricating bushing can prolong the service life of the valve.

The upper and lower shaft ends of the valve are specially sealed to ensure zero leakage of the outer seal of the shaft end.
