Ptfe Lined Butterfly Valve

About Ptfe Lined Butterfly Valve

Supported by a team of dexterous professionals, we are involved in manufacturing and exporting Ptfe Lined Butterfly Valve. We are offering this valve in various dimensions and specifications to suit the variegated demands of clients. This valve is highly acknowledged for rugged construction, outstanding performance and perfect finish. High grade stainless steel is being used in the manufacturing process of this valve. Our offered Ptfe Lined Butterfly Valve is highly appreciated in the market as this can easily isolate or control the flow of liquid, air, steam and gas.

Product Specification:

• High quality CI or SS Material used
• Unmatched Actuator and components like disc, seat, stem, and others
• Rugged construction
• Outstanding performance

Product Features:

• Single piece phenolic back up seat 
• Cosine wave on the sealing area for low operating torque 
• Blow Out Proof Steam - Outside the pressure boundary 
• Double eccentric / offset design for tight shut-off, reduced seat wear and reduced torque peak.
• Spherical seat contacts the seat smoothly
• Combination of seat and disc materials suitable for up to 600°C
• Firesafe
• Bi-directional bubble tight shutoff
• Easy disassembly without the need for special tools performed by pulling the stem out of the disc
• Reduced leak paths and vibration failures because no taper pins or disc screws are needed to attach the disc to the stem
• Actuators can be close-coupled to the valve
• Maintenance free, live loaded, Triple Seal design assures bubble tight shutoff:
• Assured leak tight sealing by a compression ring which keeps the dynamic pre-load force constant while energizing the various components of the triple shaft seal design
• Never needs adjustment of the dynamic live loaded shaft seal
• Positive valve position indication and simplified adaption to automatic operation due to the Double-D shaft drive
• Resists the effect of atmospheric corrosion due to the epoxy coated body and mounting plat

Superior Corrosion Resistance

With a PTFE lining and ductile or cast iron body, these butterfly valves offer superior resistance to aggressive acids, alkalis, and corrosive chemicals, ensuring long service life even in harsh environments. This makes them highly suitable for industries like chemical processing, pharmaceuticals, and food where contamination control and durability are crucial.


Versatile Actuation and Control Options

The valve supports manual lever, gear, pneumatic, or electric actuation, covering voltages of 24V, 110V, 220V, and 380V. This versatility enables seamless integration with various control systems, catering to both automated processes and manual operations, enhancing operational flexibility.


Broad Application Spectrum

PTFE lined butterfly valves are applicable in handling media such as acids, alkalies, water, gas, and a range of corrosive fluids. Their reliability, extensive port size selection, and adaptable installation features such as wafer and lug types, make them suitable for use in power plants, chemical manufacturing, food processing, and more.
