Introduction Features Of PTFE Electric Butterfly Valve :
The electric actuated fully PTFE lined butterfly valve is a type of valve featuring a disc-shaped closure element that operates through 90-degree reciprocating rotation to achieve opening, closing, and regulation of fluid flow channels. The valve body is typically constructed with cast steel or stainless steel as the base material, while the internal flow passage is entirely lined with polytetrafluoroethylene (PTFE) or other fluoroplastics (such as FEP or PFA), forming a corrosion-resistant protective layer.
Standard Features Of PTFE Motroized Butterfly Valve :
● The PTFE lining exhibits exceptional resistance to corrosion from strong acids (e.g., sulfuric acid, hydrochloric acid), strong alkalis (e.g., sodium hydroxide), potent oxidizing agents (e.g., aqua regia), and organic solvents.
● The disc and seat employ a soft-sealing structure, with the fluorine-lined material exhibiting superior elasticity. Upon closure, the outer circumference of the disc compresses the seat, inducing elastic deformation to establish sealing specific pressure, thereby ensuring zero leakage.
● The butterfly valve features minimal rotational torque for swift and effortless operation, supporting diverse actuation methods including manual, pneumatic, and electric drives to accommodate automated control requirements.
● The rotation angle of the butterfly valve plate exhibits a linear correlation with flow rate, enabling precise regulation of medium flow within a specified angular range to meet process control requirements.
● PTFE exhibits an extensive temperature resistance range and exceptional chemical stability, albeit with relatively low mechanical strength.
● The FEP lining material has a maximum operating temperature of ≤150°C (short-term exposure up to 150°C, long-term use ≤120°C); whereas the PFA lining can withstand 180°C momentarily, with a continuous service temperature of ≤150°C.

Description | Operating Temperature |
Service Application |
| PTFE | Virgin PTFE is the most widely used sealing material with excellent characteristics suitable for most services. It has excellent chemical resistance throughout valve industries and low coefficient of frication | -20°F – 400°F -29°C – 205°C |
General chemicals, low pressure services |
| RPTFE | RPTFE (Reinforced PTFE) is typically produced by adding 15% fiber glass to virgin PTFE. It has better pressure-temperature properties than virgin PTFE, better resistance to wear and deformation under load. Not to be used in hydrofluroic acid | -20°F – 400°F -29°C – 205°C |
For low and medium pressure services |
| PCTFE | PCTFE is a homopolymer of chlorotrifluoroethylene, featuring high compressive strength and low deformation under load | -320°F – 248°F -196°C – 120°C |
For low temperature low pressure services |
| Nylon | Nylon is a common seat material for Class 600 valves. It is highly resistance to many chemicals and abrasions, and can be used in air, oil and other gas media. It is not suitable for strong oxidization agents | -20°F – 176°F -29°C – 80°C |
For high pressure, low temperature services |
| PPL | PPL (Polyparaphenylene) is an excellent seat material with low coefficient of friction, highly resistant to pressure and temperature | -50°F – 482°F -46°C – 250°C |
