High-Performance Soft Seat Butterfly Valve

◆ New lotoke soft-seal high-performance butterfly valve adopts double eccentric design to achieve bidirectional 1:1 zero leakage function. At the starting point of the valve seat, the eccentric spherical valve plate produces a cam-like effect, which can pull the valve plate away from the valve seat without excessive torque, and the valve plate does not contact the valve seat. This effect reduces the wear of the valve seat, minimizes the deformation phenomenon, and reduces the operating torque. When the valve is closed, this cam-like action converts the rotary motion of the valve plate into a linear motion, effectively pushing the valve plate into contact with the valve seat, and the H line contact between the valve plate and the valve seat is in contact with the wiper to ensure effective In the case of sealing, avoid the accumulation of impurities in the medium.

◆ The valve plate is matched with the conical surface of the valve stem, and the matching precision is high. Under a considerable load, the valve plate can be accurately closed, the closing is reliable, and the sealing is stable.

◆ The valve seat combines the advantages of PTFE and elastic rubber, is corrosion resistant and prolongs the service life of the valve seat.

◆ The valve seat positioner and valve body groove design ensure the accurate and firm positioning of the valve seat. The full-face valve seat positioner uses high-strength bolts to be connected to the valve body in a balanced manner to ensure the maximum tightening force of the valve seat and ensure the pipe Road seal.

◆ The valve seat with reliable sealing and good supporting force is sealed by the pressure of the pipeline medium. The higher the pipeline medium pressure, the greater the sealing force. Under lower pressure or vacuum, this kind of booster valve seat Design, in the state of its own energy storage, can provide better sealing performance, the pipeline medium pressure decreases, the energy storage of the energizer will decrease accordingly, and the reasonable and unique design ensures the longer service life of the valve;

◆ Provides two-way airtight sealing capability for pipeline media;

◆ The valve seat itself has the ability to self-adjust to medium temperature changes and pipeline pressure, thus minimizing the wear of the valve seat;

◆ The valve seat is easy to replace. Just remove the valve seat positioner, after the valve plate is turned to the closed position, place the new valve seat assembly in the valve body groove, and then use the valve seat positioner to connect firmly to the valve body. .
