SUZHOU RSF VALVE is one of leading manufacturer of non-lubricated PTFE sleeve plug valve and oil and gas industry valves, we have more than 15years experience in producing cast steel un-lubricated API 599 plug valve and lifting metal to metal seat plug valve. API 599 plug valve is one kind of important quarter turns oil and gas industry valves. It has been widely used in oil and gas industrial pipe line system.
API 599 plug valve called double block-and-bleed plug valves which is high-integrity, positive shut-off valves, which serves the pipeline, liquid bulk terminals, aviation furling, refining, oil and gas production and custody transfer for the petroleum and oil and gas industries. Non-lubricated PTFE sleeve plug valve redice the constant wear by using 2 seat slips mounted independently on a tapered plug by dovetails, which mechanically retract from the seat surface piior to rotating. Valve material covers carbon steel, stainless steel, alloy steel, duplex steel, such as WCB, WC6, WC9, CF8, CF8M, 4A, 5A, aluminium bronze etc. Non-lubricated PTFE sleeve plug valves are valves with cylindrical “plugs” which can be rotated inside the valve body to control flow through the valve. The plugs in plug valves have one or more hollow passageways going sideways through the plug, so that fluid can flow through the open plug.
Sleeve Tapered Plug Valve With PTFE lined :
1. Plug valve with Sleeve type PTFE seal serves as cutting and connecting medium on the pipeline.
2. It can be used in large-scale Chemical industry.
3. It is suitable for water, steam, oil, other corrosive acid.
