Product Description
The PTFE Spring Energized Valve Seal is a pressure-assisted spring-energized sealing device composed of a PTFE (or other polymer) seal partially enveloping a corrosion-resistant metal spring energizer.
The PTFE jackets are carefully machined, filled with PTFE composites and other high performance polymers, operate from cryogenic to 250 C temperatures, and are chemically inert to practically all substances. Some varieties can also be employed in a sanitary setting.
Material
PTFE.
Filled with bronze(glass,graphite,carbon,etc.)
PEEK.
PEEK is a colourless organic thermoplastic polymer in the polyaryletherketone (PAEK) family that is utilised in engineering applications.
PEEK is a semicrystalline thermoplastic with outstanding mechanical and chemical resistance that can withstand high temperatures. The crystallinity and thus the mechanical properties of PEEK can be influenced by the processing conditions used to form it.
Application Example
1. Inside face seals used in static and rotational applications.
2. Outside face seals used in static and rotational applications.
3. In Static Service, Radial Seals.
4. In Reciprocating Motion, Radial Seals.
5. In Rotary Motion, Radial Seals.
Main Advantages of PTFE Seals:
High chemical resistance.
Withstand speeds up to 30 m/s (5 900 ft/min).
Wide operating temperature range, –70 to +250 °C (–95 to +480 °F).
Withstand pressures up to 3,5 MPa (500 psi).
Withstand dry running.
