Servicing of knife gate valves

KBK Engineering also manufactures slide gate valves that can be mounted in any direction and sealed without leakage of pipeline conveyance. The company has had many successes with these valves, including in sewage treatment, and they continue to evolve in terms of both structure and mechanism. A maintenance request was received for a similar knife gate valve with a valve plug that would not fully tighten.

Disassembly

Knife gate brought in, pneumatically operated specification
Condition of the pipe connections. The surface is a little rough and requires maintenance
Slide plate. There appear to be sliding marks and the deformation needs to be checked
The guide also showed slight rusting

Condition of components

Smooth out the marks on the upper part of the slide plate that have been deformed by beating
Check pneumatic cylinder operation → no problems

Trial run

Commissioning after replacing and caring for parts. Open state
Closed state

Smooth operation

BIn addition to the areas mentioned, parts are inspected and checked, focusing on areas that require attention when manufacturing slide gate valves. Maintenance is carried out to maintain a leak-free structure and incorporate elements that ensure smooth operation. Major components can be repaired, manufactured and modified to suit the process in which they are used and the materials they carry.
