Overview For the improvement of valve sealing performance and reliability the patented round SOFT SEATED seat (rubber cushion seat) is inserted into the area where the valve disc moves up and down. If the valve is shut off, the disc drops and is adhered to the soft seat and then valve metal seat. Such double sealing blocks fluid flow without leakage. It can be installed to the water/oil/gas/slurry-mixed fluid line where some chronic problems resulting from foreign matters accumulated under the valve and seat leakage occur to take care of them. This flow-control and shut-off valve in fire-safety design is applicable to important lines.
