Product Description

PTFE and elastomeric spring energized seals For Valve

SPT SEALS COMPANY manufactures PTFE and elastomeric spring energized seals and sealing systems. Spring Energized Seals can be used in static, reciprocating and slow to medium rotary applications. Unli`ke many other seals where you must size your seal application around standard size seals, Spring energized seal can be manufactured to your product. While standard size seals are something we make everyday, we make seals in any size needed. Used as piston, rod, or face seals, the SPT(SI PAI TUO) spring energized seal is engineered to meet your exact specifications and design intent.

Spring Energized seals

The Spring Energized PTFE Seal is a spring- energized, pressure-assisted sealing device consisting of a PTFE (or other polymer) seal partially encapsulating a corrosion-resistant metal spring energizer. The PTFE jackets are precisely machined, filled with PTFE composites and other high performance polymers, function at temperatures ranging from cryogenic to 250 C and inert to almost all chemicals. Some types also can be used in sanitary environment. Seals are available with a variety of spring energizers, each having characteristics to meet specific requirements. Spring loading can be adjusted to meet critical low or extremely high requirements in dynamic applications.
Radial Seals in Static Service. Radial Seals in Reciprocating Motion. Radial Seals in Rotary Motion. Inside face Seals in Static and rotary Service. Outside face Seals in Static and rotary Service.
Section structure Symmetric, for Rod, for Piston are available.
Spring type: U shaped spring(Type 400) Round wire spring (Type APS) O shaped spring (Type 103)
Groove Standard Heel Groove. Extended Heel Groove Flanged Heel Groove.
Size Both imperial and metric sizes are available on all types.

and Christmas tree etc. Wellhead equipment seals for oil and gas applications can be exposed to everything from harsh drilling and
completion fluids to high temperatures ,pressures and contact forces .

Spring energized PTFE seals perform reliably in a variety of applications where conventional elastomeric seals fail due to chemical attack, extreme heat or cold, friction, extrusion or compression set.

PTFE seals have three basic design elements:

• A pressure-actuated U-shaped jacket
• A metal spring loading device
• High performance polymeric seal materials

Spring energized PTFE Seals are classified as follows

- VS-Series - V-Spring Seals
- SC-Series - Slanted Coil Spring Seals
- HS-Series - Helical Spring Seals
