Lug Type Concentric Butterfly Valve

Features

The first advantage is performance.
It fully opens or closes within only 90 degree travel. So, it can operate, at least, three-to-five times faster than conventional gate valves do.
Also, DK BF-series provide higher Cv figure and greater prssure recovery with a thin disc profile.

The next is universal compatibility.
One leading merit of DK BF is compatible with most world flange standards.
And, thanks to ISO-mounting pad, diverse actuator can be directly mounted to DK BF without any modification.
The third is originally designed seat ring.
Grooves are molded on the surface of the seat surface so as to reduce operating torque. And, our original retaining method is adopted.
That results in tight shut off service , low operating torque and long service time.

Furthermore, built-in O-ring can function as a gasket between a butterfly valve and a counter flange.
The last is economic feasibility.
Compact and lightweight DK BF is much economic compared to traditional gate and globe valves.
And, easy installation and maintenance leads to saving your budget.

Lastly, to your satisfaction, various materials from Cast iron to Duplex or Monel or Inconel can be employed.
