200mm Sleeve Plug Valve API 599 WCB 8 Inch Full Bore Sleeved Plug
Valve 150LB DN200 SS Sleeve Lubricated Plug Valve
Description
Plug valves, also called cock or stop-cock valves, date back to ancient times,
where they were developed for use in citywide Roman plumbing
systems. Today, they remain one of the most widely used valves for
both on/off and throttling services. Their design is fairly simple;
the body is comprised of three main parts: body, cover and plug.
The plug is a cylindrical, tapered, or generally cone-shaped device
that can be raised or lowered within the seat to maintain, restrict
or completely shut off flow. The valve is opened by rotation, with
the plug itself being the only element that is capable of movement.
Early models of plug valves used metal-to-metal seals that were
nonlubricated. This design is still used, but problems with galling
and sticking limit their usefulness. The use of lubricant between
the plug face and the seat eliminates most of these problems. The
lubricant helps to control leakage around the plug, reduces wear
between the valve contact surfaces, and slightly lifts the plug to
reduce the operating torque required to operate the valve.
Product structural features
Sleeve
type soft sealing plug valve acc.API is applicable to the cutting and connection of pipelines medium
that are used in various industries such as petroleum.chemical
industyy etc under nominal pressur of PN1.6-16MPa and working
temperature of -29-180degree.
Main structural features:
1,The produt thas reasonable structure,reliable sealing,excelent
performance and beautiful appearance
2,Its sealing is realized by the sealing face around sleeve it has
unique 360 degree metal edge for protection and fixing of clipping
cover.
3,There is no cavity in the valve for accumulation of medium.
4,Metal edge provides the funtion of self-cleaning when the plug is
rotated applicable to the operation condition that is glutious and
apttosmudge.
5,Its characteristic double-dircction flow makes installation and
use more convenient.
6,The materials of the parts and sizes of flanges can be reasonably
configured according the actual operation condition of the
requiements of the custiomers.so as to meet the variious needs of
engineering.
