Metal face spring PTFE seals supplier


The helical spring engineered static face seal design of the spiral spring combined arc lip, and the pressure comes from the inside.


The Helical spring design of the end seal provides a high load stainless steel exciter. The spring is used to seal the shaft and piston radially for low-temperature propellant sealing. Coil springs are used for chemical corrosion or extreme high or low temperature sealing requirements.


With high spring load, it is the best choice for low temperature, gas and low pressure static flange sealing applications.


Applications: valves, compressor cylinders, cryogenic equipment, rotary joints, etc.


Advantages:

1. Passed BS6364 test (-196℃);

2. High load helical wound spring with small deflection range;

3. Exquisite structure, can be installed in the standard O-ring groove;

4. Excellent chemical corrosion resistance and heat resistance, dimensional stability;

5. Greatly improve the sealing performance and service life;

6. Low friction coefficient, very smooth even in very low speed applications.

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.
