Product Description:
The high-performance butterfly valve plate and sealing ring adopt a unique eccentric structure, which has the characteristics of compact structure, good cutting performance, long service life, etc., and has both adjustment and shut-off functions. It is widely used in chemical industry, electric power, light textile, food, medicine, paper and other industrial sectors, as well as municipal engineering, water plants and other pipelines to cut off or adjust the flow control of tap water, sewage, oil liquid or air, gas, natural gas, water vapor medium.
Features:
The valve body adopts integral casting technology, which is compact in structure, small in size and light in weight;
The valve plate is installed eccentrically, and when closed, the valve plate expands outward to achieve a good peripheral sealing state; When opened, the valve plate and the sealing ring are quickly disengaged, effectively preventing the wear of the sealing ring;
The design of the sealing ring is novel, concise and maintenance-free;
The sealing ring form is available in two types: soft seal and metal seal to meet the requirements of different working conditions.
Due to the eccentric structure, the operating torque is greatly reduced;
The flow resistance is small, and the forehead flow coefficient is large, which is about 3 times that of single-seat valves of the same caliber.
Strong self-cleaning ability and long service life;
The valve adopts a column flange structure, and the process pipeline adopts a clip-on type installation;
The three types of standard actuators (pneumatic piston, pneumatic membrane and electric) are interchangeable.
