  • Product Detail

Ball valve high pressure lip seals


Spring energized seal:
The BVR series is made of a canted level spring and a polymer jacket, which is mainly used as a stem seal.

The polymer jacket's material includes virgin PTFE, TFM, PCTFE, PEEK, etc.

The helical wound spring's material includes Stainless Steel, Elgiloy, Hast Alloy, etc.

When the pressure is more than 900LBS, an anti-extrusion ring is required; 

This multifunctional design combines two seals and a guide bearing into an integral component. Bi directional seals are suitable for medium temperature / pressure applications requiring simple assembly and quick replacement. When designed without an inner diameter, it also acts as a floating piston.


When low temperature and static, reciprocating or rotary motion are involved, the recommended geometry of the spring energized device is a simple coil spring. However, dynamic or static motion may require the use of solid springs. Recommended spring materials include stainless steel, 301 / 304 /316 stainless steel, or in some applications, Hastelloy, Inconel, or Elgiloy.


Advantages:

1. Material compound passed API  6A FF/HH Immersion Testing;
2. High load canted level spring with small deflection range;
3. NACE approved energizers available for oil and gas use.

Cryogenic valve seals
Cryogenic ball valve stem seal

In LNG operations, valves can regularly encounter temperatures below -320 F (-196 C) and pressures above 750 pounds per square inch (psi). They are also subjected to periodic variations in temperatures known as “thermal cycling,” which can result in hardware expansion as well as shrinkage and material stresses. These factors make reliable, long-term valve operation an engineering challenge.
