Welcome to SUNG DO Valve, the expert manufacturer
of butterfly valves and pneumatic actuator.
Based on accumulated technological knowledge and
trust of the past 30 years since its establishment in 1979
in pioneering the market for industrial valves, the know-
how of our company is well recognized in the field by
supplying mammoth class valves of 3,000 mm or larger to
representative petrochemical companies and desalination
plants in the Middle East. In Plant #1, we are responding
to customer demands for cost reduction and prompt
delivery using the in-house processing processes that
are made possible through the use such in-house facilities
as large-scale turning, boring, and radial machines. We are
also satisfying diverse inspection conditions such as water
pressure and air test using the large-diameter inspection
equipment that have been designed and developed within
the company. In Plant #2 where all processes are automated,
we have introduced more advanced facilities and are
implementing precision processing as befitting to a company
that has developed and mass produced our own pneumatic
actuators in Korea for the first time. Accordingly, we are
carrying out on-off and control mode tests with no-mistake
data values from small-scale to large-scale heavy-duty
actuators using advanced torque measuring equipment.
As a company that pursues excellent performance and
compact design, Seongdo Valve Co., Ltd. will not be satisfied
with domestic leadership but will make every effort to become
a super-class corporation that pioneers into the overseas market.
Thank you.
