1. The valve stem packing is an essential component of valves, which is covered around the valve stem. The purpose of valve packing is to prevent leakage.

2. The sealing ring has good sealing performance under working pressure and a certain temperature range, and can automatically improve the sealing performance with the increase of pressure.

3. The friction between the seal ring device and the moving part should be small, and the friction coefficient should be stable.
4. The sealing ring has strong anti-corrosion ability, is not easy to aging, has long working life and good wear resistance, and can be automatically compensated to a certain extent after wear.
4. The structure is simple, easy to use and maintain, so that the sealing ring has a longer life.

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.

V-ring stem packing provides the rigid secondary stem seal

 

Wellhead Seal Ring usually include gate Valve seals ring,seat seal ring,Choke Stem Seal ring,body bushing seal ring ,PE Secondary
seal,BT secondary Seal,CS seal ring,FS seal ring,Seal ringP seal ring ,hammer union seal ring ,BX gasket ring, R gasket ring,RX

gasket ring ect.Application:Includes wellhead gate valve,wellhead plug valve,wellhead choke valve,wellhead check valve,well head
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
