100% Made in Korea (Casting & Machining for BODY, DISC, SEAT, STEM)

KB Valve Technology uses domestic rubber materials such as Donga Tire CMB and Korea CMB companies. We use optimal high elasticity EPDM rubber seat product for butterfly valves with strong properties for water resistance, chemical resistance and ozone resistance with Advanced and Optimized Mixing Technology.

- Features and Advantages
● We guarantee full close without leakage by carrying out factory tests under all the specified pressure.
● The primary sealing formed by the contact surfaces of the seats, stem and hub is kept a complete stem sealing at the
      specified pressure and the body is completely separated from the fluid.

● It provides complete sealing to all parts of the disk by processing the polished disc edge of the disk in a flat structure on
      top and bottom of the seat.

● The O-RING formed on the seat, maintains a firm flange airtightness and no need to use of gasket between flanges.
● Stem structure to be able to do well for strong force and disk operation.
● Depending on the order specification, seat material can be used with various materials, e.g. EPDM, BUNA-N, etc.
