Metal to metal sealing or rubber sealing
Triple eccentric quarter –turn design
Bi-directional tight shut off
Acid /Caustic /Chloride
Oil and so on
Triple eccentric oblique cone seal is taking a section to design on the cones,between the axis of the stem and disc sealing surface offset a size 1 , and between seat rotary axis and the bady channel form a eccentric Angle called offset 3, so that 's the formation of triple eccentric . When the butterfly valve are opened from 0 to 90 ,the seal face of the butterfly plate will immediately break away from the valve seat sealing surface , in the 90-0 is clossed ,only at the closing moment, the butterfly plate cone sealing surface contact and compact with the conical seating. So there are no friction between the seat and the sealing surface of butterfly plate, which improves the service life of the valve.
Plate seal structure is fixing the multi-layer sealing ring on the valve plate by bolt through the retainer flange, of which the advantage is easy and quick disassembly, The technician is allowed to enter the pipe to carry out on-line maintenance when there are no media accessed the large diameter valves, which reduces the maintenance cost.
Body pressure seal structure is fixing the multi-layer sealing ring on the valve body by bolt, of which the advantage is that the plate of valve is simple and has a rigid structure , large flow,small flow resistance, mass medium erosion , long service life,applicable in the high temperature line.
Double seats is design seal seat of the body and the valve plate to break down movable structure , which can compensate for sealing through the spring force of the spring by the seat on the bod,which good bilateral direction sealing function.
