Product Description

                                                        Polymer Soft Seal Rings    

PTFE is an ideal material for ball valve seats due to its low coefficient of friction against metals, chemical inertness and general effectiveness as a sealing material.
 

We manufacture premium quality PTFE Ball Valve Seats. Besides, we also offer valve stem sealing gasket that are widely used in ball valve seat gaskets. These products are manufactured incorporating molding methods using PTFE granular resins. PTFE when compared with other plastics offer exclusive properties against chemicals and temperature.

The most common fluoropolymer application is in process valves. We provide valve seats, manufactured from a wide range of materials, including Virgin PTFE and filled PTFE, Modified PTFE, PCTFE, PEEK and filled PEEK materials, UHMWPE...

• Seats and seat inserts
• Thrust washers and back up rings
• Stem packings
• High-performance spring energised body seat and stem seals

Material Name	Main Properties	Notes	Temperature Range
VIRGIN PTFE	Very low coefficient of friction and excellent chemical resistance.	FDA approved	-40°C to 260°C
15% Glass Filled PTFE	Decreased compressive strength and lower deformation under load than virgin PTFE.	Abrasive material	-40°C to 260°C
Modified PTFE TFM	Much denser polymer structure than Virgin PTFE. Displays better stress recovery.	Modified TFE Polymer	-40°C to 260°C
Carbon Graphite filled TFM	Lower thermal expansion-contraction rate than conventional TFM.	Ideal for use on steam and thermal fluid applications	-40°C to 260°C and even300°C on Thermal Fluid applications
PCTFE	Excellent for cryogenic and Oxygen use.	A homo-polymer of Chlorotrifluoroethylene	-240°C to 120°C
UHMWPE	Highly resistant to corrosive chemicals, with the exception of oxidising acids and organic solvents.	Also known as High Modulus Polyethylene (HMPE) or High Performance Polyethylene (HPPE)	-40°C to +80°C
Virgin PEEK 450G	Excellent chemical resistance and mechanical properties at elevated temperatures.	An organic polymer thermoplastic	-40°C to 260°C
Carbon Filled PEEK	Many similar properties to Virgin PEEK. Particularly suitable for elevated temperatures and high load situations.	Low coefficient of friction and suitable for many extremely corrosive applications	-40°C to 260°C
Acetal and Delrin	Displays good resistance to wear and deformation under load.	Excellent for valve seat applications	up to 80°C
