These Valves are designed and developed with latest technology and
are very suitable for chemical processing industries. They provide
maximum corrosion resistance and elimination of product
contamination at reasonable cost. The molding process used to line
the ductile iron body provides a uniform 1/8 inch thickness of
fluoropolymer on the wetted surfaces. The plug lining is rigidly
locked into place by holes through the plug itself. Dovetail
grooves and locking rings at several locations in the body prevent
shrinkage and blowout lining.

Lined Plug Valves use high precision investment casting method for
all major pressure holding components.
The standard base model offers:
Carbon Steel body, plug and cover (ASTM A216 Gr. WCB).
Low porosity PFA (Perfluoroalkoxy) as standard liner
All cast parts have an acrylic based coating prior to lining for
added protection from corrosion attack due to permeation
Lined Plug Valves feature an unpigmented virgin PFA lining applied
by Transfer Molding and locked into castings by machined
dovetail-shaped grooves, and cast dovetail-shaped recesses in body
castings and cast holes.
Prevents liner collapse in vacuum conditions
Prevents blow out in high temperature and pressure combined
Transfer Molding insures equal distribution and consistency of
liner throughout the entire surface of the lined components as per
No weak sections in the valve liner
All liner defects are directly visible
By design, Lined Plug Valves are cavity-free both in open and
The interface between the tapered outer plug and the tapered inner
body liner provides a 360° primary sealing area. Additional sealing
levels are achieved by a delta ring and PTFE diaphragm, both
protected by a metal diaphragm. The metal diaphragm assists in
encapsulation, acts as an antistatic device, and is a metal seal to
atmosphere, in case of PTFE failure.
Compression seal (upstream and downstream)
Sealed at both plug and stem
Sleeve type soft sealing plug valve acc.to ANSI is applicable to
the cutting and connection of pipelines medium ,workin temperature
Main Structural Features:
The product has reasonable structure, reliable sealing, excelient
performance and beautiful appearance.
Its sealing is realized by the sealing face around the sleeve. It
has unique 360 degree metal edge for protection and fixing of the
There is no cavity in the valve for accumulation of medium.
Metal edge provides the function of self-cleaning when the plug is
rotated, applicable to the operation condition that is glutions and
apt to smudge.
Its characteristic double-direction flow makes installation and use
The materials of the parts and sizes of flanges can be reasonably
configured according to the actual operation condition of the
requirements of the customers, so as to meet the various needs of
