The PFA, FEP, PTFE, & Teflon lined Butterfly Valves have insensitive coating or lining at the internal surface of the valve body. The additionally added coating prevents the valve from exposure to caustic or corrosive chemicals.
Lined Butterfly Valve is a reliable, leak-free service valve designed for a wide range of demanding requirements in corrosive chemical applications and process industries.
FEP & PFA Butterfly Valve
The FEP and PFA lined Butterfly Valves followed all standard criteria according to the API. FEP Valves can bear up to 160°C operating temperature and PFA can sustain up to 200°C operating temperature.
PTFE Lined Butterfly Valve
Centric Disc PTFE lined Butterfly Valves are available in a 2” to 12” inch size range. PTFE sleeve Butterfly Valves with Mirror Finish Disc are very useful for powder applications as well. PTFE coated sleeve brings all the properties of PTFE. Due to this, the PTFE lined Butterfly valves can sustain 180°C operating temperature and easily handle extremely corrosive media.
The PN 10 pressure rating of lined Butterfly Valve becomes ideal for high pressurized media like gases, High chemicals, and viscous materials and it can be increased to PN 16 but on request. All these valves are available in wafer sandwiches and also provided the lug type body on request by the valve manufacturers.
The FEP and PFA lined Butterfly Valves are designed and manufactured under API 609 category / BS – EN – 593.
The FEP & PFA Butterfly Valves are available in 2″ to 20″ inches size range
The PFA & FEP Butterfly valves are available in multiple body materials such as Cast Iron, WCB, CF8, CF8M, and CF3M
The Cast Iron, Cast Steel, CF8, and CF8M materials are used in the making of Disc for Butterfly Valves.
The PTFE and FEP materials are used for the seat in lined Butterfly valves
160°C (For FEP), 200°C (For PFA)
Lined Butterfly Valves comes up with PN 6 pressure rating and it can be increased to PN 10 on request.
