High-Quality FSVO-V for Dynamic Face Air Inflatable Applications
FSVO-V
Quantity:
1. Application and properties
Suitable for end static seal or rotary seal, preventing pressure fluid leakage from inside out, and providing good sealing performance under medium and high pressure
Low friction coefficient, low contact pressure with the mating surface, and the friction with the mating surface is the smallest among all types of seals. It can work with or without lubrication, It has good wear resistantance and a long service life.
The working medium of the sealing sleeve is widely adaptable, and other chemicals do not react with it except soluble alkali metal, high temperature fluorine gas and chlorine trifluoride.
Operating temperature range from -200°C to +250°C. It is suitable for special working conditions such as extremely high speed, extremely low speed, etc.
It is suitable for aerospace, military, and industrial sealing groove sizes. The standard installation groove is the same as the standard O-ring installation groove, and the size is small. It can also be designed as a non-standard component to meet the sealing requirements of any size of groove, and the groove can be open or semi-open.
It can adapt to large eccentricity and end-face runout (at low speed).
2. Standard material
Sealing ring: filled PTFE
Spring: SUS301, 302, 304, 316 or 718 Default use SUS301, please specify if there are special requirment /400A

5. Marking it method
Mark with the dimension of installation groove as below:
FSVO “Groove inner Diameter d”ד Groove Outer Diameter D”ד Groove Height L”-Spring Material”V,
For example: FSVO100×90×4.7-316V means, Groove dimensions:φ100×φ90×4.7,Spring material 316
