Characteristics
The pneumatic stainless steel lug knife gate valve is made of premium 304/316 stainless steel for excellent rust and corrosion resistance. The threaded lug structure allows single-side blind installation and firm fixing for pump ports and pipeline ends. Full straight bore design prevents slurry and dust blockage. Equipped with an explosion-proof pneumatic actuator, it supports fast remote on-off control for chemical, environmental and seawater treatment projects.
Advantages
1.Full stainless steel (304/316) structure features outstanding anti-corrosion performance against acid, alkali and sewage, effectively avoiding rust and leakage for long-term service.
2.Threaded lug design supports single-side blind closure and unilateral connection. Firm installation with tension resistance makes it perfect for pump ports and pipeline ends.
3.Full straight bore prevents material blockage. Explosion-proof pneumatic actuator enables fast and stable remote automatic control with low maintenance cost.
Packing
Standard export wooden case packaging
Application Scenarios
The CF8 knife gate valve widely used in chemical corrosive pipelines, sewage pump ports, seawater desalination, papermaking sludge, pharmaceutical and food slurry, mine granular medium and pipeline end cut-off systems.
