Features
Double guided disc and the valve can be installed horizontally or vertically.
The special designed spring controls the valve’s closing for silent operating.
The sealing of seat and rubber packing is unusually. When the valve closes, the disc presses the packing lightly. When the pressure rises higher, the disc touches the seat and no longer presses the packing any more, If the packing is pressed exceedingly the seal of the valve will be destroyed.
