Fluoro Seal Sleeved Plug Valve, ASTM A351 CF3, 8 Inch, CL150

Product Name: Fluoro Seal Sleeved Plug Valve
Design Standard: BS 5353 & API 6D
Body Material: ASTM A351 CF3, Stainless Steel
Size: 8 Inch, DN200, 200 mm
Pressure: Class 150 LB, PN20

Bayonet type tapered plug valves are self lubricated PTFE bushing embedded in the body and are pressurized to prevent leakage between the bushing and the body. Taper plug valves in use of cutting sleeve type has no sealing grease injection may cause pollution, two-way flow, adopting low torque, unique 360 degree metal lip protection and fixed card sets, make direct contact with no metal to metal seal parts, for taper plug valves of cutting sleeve type has the good seal performance, and can be avoided if sealing surface phenomenon. Its applicable scope is wide, the friction factor is small, the service life is long, and is the non-metal - metal seal, may reduce to the plug processing request, therefore to the small and medium caliber plug valve more generally USES the bush structure form.

Product Features

Zero leakage: With primary sealing by sleeve (lining in case of lined plug valve), secondary sealing by diaphragm and tertiary sealing by wedge ring, the plug valve assures zero leakage of the fluid flowing through the system.

Secure sealing: The sleeve is positively locked in the body with the locking ribs located in the body to assure secure sealing.

Cavity free: There are no cavities in the body, the plug is surrounded completely by sleeve, so there is no possibility of fluid accumulation and contaminate feature processing. This cavity-free design also prevents sticking.

Non lubrication: The PTFE sleeves have a low coefficient of friction and acts on a lubricant. Hence ease of operation is assured even though valve unopened for a period.

Low maintenance: The sealing pressure can be regenerated by the adjustment bolts provided on the cover without disassembly for repair. On line repair is easy as the plug is top entry type which will reduce the shutdown time of the plant.

Superior in line sealing: The plug is completely surrounded by the sleeve, providing a large circumferential sealing surface from port to port.

Self cleaning: As the plug rotates, the port lips located throughout 360° provide a self cleaning action to remove stealing and adhering media, facilitates no seizing and no sticking.

Adjustable sealing: When seal presence adjustment is required due to sleeve wear, slight rotation of adjustment bolts pushes the plug downwards thereby providing extra sealing pressure.

Antistatic electricity: Static eliminator (only in case of sleeved plug valves) is always in contact with the plug and releases the static electricity generated from the free floating fluid to the pipeline.

Compact design: Taper plug with trapezoidal shaped port, one-piece body and less number of parts required to construct the valve make a compact and cost-effective plug valve.
