High-performance butterfly valve
The triple-offset butterfly valve uses a unique triple-offset structure for the valve disc and sealing ring, featuring a compact structure, excellent shut-off performance, and long service life. It combines both regulating and shut-off functions. It is widely used in chemical, power, light textile, food, pharmaceutical, papermaking industries, as well as municipal engineering, water plants, and other pipelines to cut off or regulate the flow of water, sewage, oil, air, gas, natural gas, and steam. <br/> This series of products has nominal pressure ratings of PN(MPa) 0.6, 1.0, 1.6, 2.5, 4.0 (150lb, 300lb); valve body diameter range DN80~1200 (3”~48”); -60~+450℃; multi-layer sealing, achieving bidirectional zero leakage: with all-metal hard sealing, it reaches Class V leakage, and the flow characteristic is approximately equal percentage.

Features:
The valve body uses integral casting technology, resulting in a compact structure, small size, and light weight.
The valve disc is installed with a three-eccentric design. When closed, the valve disc expands outwards, achieving optimal peripheral sealing; when opened, the valve disc quickly separates from the sealing ring, effectively preventing sealing ring wear.
The sealing ring design is novel, simple, and maintenance-free.
The sealing ring is a multi-layer metal hard seal, suitable for harsh working conditions.
Due to the three-eccentric structure, the operating torque is greatly reduced.
Low flow resistance, large rated flow coefficient, approximately 3 times that of a single-seat valve of the same diameter.
Strong self-cleaning ability and long service life.
The valve can be used with flange or double-flange structures.
Standard actuators (pneumatic piston and electric) are interchangeable.
