[Essential information]
The
manual clamp type gate valve (knife gate valve) has compact design,
small space occupation, light weight, easy installation, wear resistance
and anti blocking measures, so it is easy to maintain and long service
life.
As required, a plurality of flushing openings are provided
around the valve body for flushing directly with air, steam or water to
prevent gradual accumulation of sediment, particularly for difficult
input fluids.
The abrasion resistant folding
cone made of poly rubber or Ni wear-resistant cast iron is installed at
the inlet end of the knife gate valve, so that the particulate material
can be directly washed on the seal so as to improve the working
conditions and prolong the service life.
The upper end of the
knife plate is provided with a polytetrafluoroethylene and a mud scraper
which can prevent the scrape substances such as dust and gravel from
entering the stuffing box.
It adopts a full circle design, the end of
the knife plate is processed into a knife edge, with high finish and
good sealing performance.

[Valve features]
1, ultra short structural length, saving material, can make the whole weight of pipeline system is greatly reduced.
2, the use of small space, can effectively support the strength of the pipeline, can reduce the possibility of pipe vibration.
3,
the selection of austenitic stainless steel gate, corrosion resistance
greatly improved, can effectively prevent the gate corrosion caused by
the leakage of seal.
4, the sealing packing adopts flexible PTFE, reliable sealing, easy and flexible operation.
5, the gate with the knife, can effectively brake off all kinds of debris in the medium.
6,
such as the use of hard sealing stainless steel, the valve to do spray
welding treatment, it can be a good expansion of the valve temperature,
pressure requirements.
[Adaptive condition]
Knife
gate valves are widely used in industries such as chemicals, coal,
food, sewage, paper making, steel, etc., and are ideal sealing valves.
