PEEK Valve Seats
Description
Teflex PEEK Valve Seats Are Precision-Machined Sealing Components Cut From Extruded Virgin PEEK Rigid, Load-Bearing Alternative for High-Pressure Fluid Control Systems Where Standard Fluoropolymer Seats Reach Their Limits in Creep, Gap Extrusion and Service Temperature.
PEEK’s Semi-Crystalline Structure Gives the Seat High Compressive Strength, Dimensional Stability and Creep Resistance Under Sustained Differential Pressure. The Seat Holds Its Sealing Geometry Through Repeated Operating Cycles in Ball Valves, Subsea Assemblies and High-Pressure Gas Isolation Systems.
Features
• 100% Virgin PEEK
• Broad Chemical Resistance
• Minimal Moisture Absorption
• Extruded Stock, Stress-Relieved
• Seats, Backup Rings and Carriers
• Custom OD, Bore and Seat Profile
• Resistant to Rapid Gas Decompression
Benefits
• No Special Storage
• Extended Service Life
• Fewer Maintenance Calls
• Drop-In Fit to OEM Dimensions
• One Material, Many Valve Types
• Samples Before Series Production
Advantage
• Less Cold Flow Than PTFE
• Holds Bore Where PTFE Relaxes
• Non-Galling, Unlike Metal Seats
• Higher Pressure Than PTFE Seats
• Without Hard Filler to Score the Ball
• Higher Temperature Than PVDF or PPS
