The standardfor controlled flow
For over three decades WONDAE TGK has been opening and closing the flow at the most critical points of waterworks, fire protection and plant piping.
0.1 mm is what makes a leak
Seat face and stem accuracy decide how long a valve lasts. Every machined part is inspected before it moves on.
The machine cuts. A person checks.
Automation delivers the tolerance, but the last judgement is human — and it catches what the drawing does not show.
Every dimension measured and recorded
Full dimensional inspection with recorded measurement data means any quality issue can be traced to its source.
No valve ships before it passes
Pressure, tightness and performance tests follow the criteria of the KS, KWWA and KFI certification programs.
Ready to ship the moment it is needed
Common sizes are held in stock. On an urgent site, delivery time is part of quality.
