non rising stem flange knife gate valve

Resilient renewable Seated,two-way sealing ,zero leakage,long lifetime,heat-resistant,corrosion resistance,well seal performance

 knife gate valve

With GS,CE certificate Non-toxic,environmental-friendly material Customized design offered High quality,reasonable price

Our  production process are made under ISO9001,CE ,API  strictly

we can produce many kinds offloating ball valve such as 3 piece floating balll valve

2 piece floating ball valve,reduce ball floating ball ,top entry floating ball valve,etc

 

Note: as for the difference working condition, difference working condition difference design

,so we have to redesign the products according to your working codition. The picturs

below designed before are served as reference.

                                                                       

knife gate valve type features:

1, seal by structural ceramics, can prevent solid grain scour to seal face, wear, ensure valve seal

lasting effective.

2, single seat design can effectively prevent the deposition of slag and jam.

3, single seat, one-way sealing.

4.the valve plate design is flat with blade shape, easy to cut materials or granular media, the valve

plate close to seal face, shave their the quality and slag particles which are stick to seal face and

valve plate , short type structure design makes the body more compact structure.5. choose packing also adopt  the ptfe braid rope, seal depth design enough sealing and reliable.6.working principle: a. low pressure difference condition, gate main through stem external force and

guide pad/, its seal face and seat close together joint sealing; B. high pressure difference state , the

valve plate realize the seal face seal mainly under high pressure end ressure promote 7. the valves are suitable for power plant dry ash system, the warehouse pump material out conveying,

also can be used in mining, paper making, chemical industry etc of all kinds have worn slag, cinders,

and slag water mixture medium in pipelines as an opening and closing.Nominal pressure IS 1.0 MPa,

applicable temperature less than 80 °C.8. the valve seal adopt double seal structure type, soft seal + metal seal, metal sealing layer effective

 protection soft sealing layer, increase the life of the seal; The valve body and cover adopt WCB steel

castings, filler/packing used high quality wear-resisting mixed Flexible

Purpose/Application:

Apply to solid such as ash, mud slag, coal slurry, pulp, sewage of solid, liquid-solid, and

gas-solid two-phase medium conveying system in the pipeline for switching valves, such as

heavy medium in the piping system for coal preparation plant.
