Size Range: 25mm to 150mm
  Cross-Section View
1.) Low torque operation
2.) One Pc Ductile Iron Casting Body with corrosion resistance PU paint
3.) PTFE Diaphragm for secondary seal provides static and self adjusting dynamic stem seal
4.) FEP/PFA encapsulated taper plug provides positive circumferential in line sealing
5.) Fully locked in, unpigmented FEP/PFA uniform lining throughout body and face area helps prevent blowout or collapse of the liner under full vacuum/high pressure
6.) Unpigmented FEP/PFA lining tested at 20,000 Volts for defects, is made from highly corrosion resistance FEP (150°C) or PFA (200°C)
7.) Standard Port Design
Feature & Benefits
Liner Locking
The lining is securely locked into the deep machined groove slot into the body & holes in casting plug under melting processible of FEP or PFA. This prevents liner to collapse or blow out under full vacuum/high pressure applications in conjuction with high temperature
Large Contact Area
The full circumferential sealing area is created by the interface between the taper plug & body liner. Due to the compression sealing the valve is used in either direction.(Bi-directional)
Cavityless design helps to prevent accumulation of material between the body liner & taper plug

Large Port Area
Ensures low pressure drop with higher flow rate

Double Sealing Arrangement
Primary seal between the taper plug & body liner. The secondary seal is reversed V lip diaphragm which is pressurized and ensures excellent stem seal
Standard Design
The Brightech™ Fully Lined Plug Valve are designed in accordance with flange dimension of ANSI B16.5 & face to face dimension of ANSI B16.10 permits these valves to replace with any standard plug valves without altering existing piping
