DKSB Engineering (M) Sdn Bhd provides professional gate valve replacement to stop leakage, restore smooth on/off control, and reduce downtime for your water, chilled water, or process piping. We support fast site response across Kuala Lumpur and Selangor.
This service removes a faulty gate valve and installs a suitable replacement with proper sealing and testing. The goal is a clean, stable system restart with less risk of repeat leaks.
To speed up quoting: share pipe size (inch/mm), valve type/connection (flange/thread), fluid (water/chilled water), and photos of the valve area.
Gate valves often work for years, but wear and site conditions can cause problems. Replacing early helps prevent water damage and avoids emergency shutdowns.
Leak near the valve stem can happen when packing is worn or loose.
Aging parts may no longer shut off properly, causing seepage even when “closed”.
Corrosion or debris can make the valve hard to turn and damage sealing surfaces.
Incorrect size or installation can lead to repeated leaks and poor operation.
Common warning signs: dripping at flanges, wet floor near valve, valve cannot fully close, stiff handle, or frequent “minor leakage” that keeps coming back.
We follow a clear workflow to reduce risk and keep your system stable. We prioritize safe isolation and proper testing before handover.
Check valve size, location, isolation points, and required shutdown steps.
Stop flow and reduce pressure before opening any connection.
Remove old valve, clean surfaces, install new valve with correct sealing.
Leak test and confirm smooth open/close operation before restart.
If the piping area is tight or rusty, we will advise the safest method (and any needed extra support work) before proceeding.
Downtime depends on valve size, access, and whether the line must be drained. We aim for a clean restart with minimal disruption.
| Scope Item | Purpose | Notes |
|---|---|---|
| Site assessment | Confirm correct valve size and connection type | Helps avoid wrong parts and delays |
| Isolation & draining (if needed) | Make the work area safe and dry | Depends on system layout |
| Valve replacement | Restore shut-off control and stop leakage | Proper sealing is critical |
| Leak & operation test | Confirm no leakage and smooth valve movement | Done before system restart |
For critical facilities, ask about planned shutdown support and a step-by-step replacement plan for multiple valves.
