We are a unique name in the industry as a leading Exporter of Double Block Bleed Valves in Seoul, Seoul, Korea South.
a ZERO LEAKAGE
A valve selection is very important in petroleum industry. An wrong valve selection causes the decrease of income, the pollution of product and the increase of product maintenance cost.
In multi-product system, valve should stand cycle variation of frequent and cut off completely in up-stream sealing and down sealing. Double block and bleeding valve is developed for satisfying a demand fact of metering station, tank farm marine loading docks, blending plant.

a NO ABRASION
D.B.B can do complete isolation without leakage in a design pressure, and the design of valve is that a seal doesna t contact with valve body during valve opening or closing. The moment the last of closing operation a seal contacts with body, the force consists of only pressure force. A shearing force doesna t be suspended. In all opening, handle operation, a seal in separated form body, and maintain this state during plug rotation. This takes off the abrasion of seal and extends a life.
