Rubber seal of boost valve IV
The rubber seal of boost valve IV is the key sealing component of the boost valve, and mainly undertakes the following functions
- Sealing performance
The rubber seal forms a sealing barrier inside the boost valve to block the leakage of gas or liquid and ensure the sealing performance of the boost valve.
- Buffering effect
The rubber seal has a certain elasticity and deformability, which can absorb the impact and vibration force during the operation of the boost valve and play a buffering and protective role.
- Wear resistance
Rubber seals must have good wear resistance for long-term use under harsh working conditions such as high temperature, high pressure, and high speed.
- Seal life
The rubber material, surface treatment process, structural design and other factors will affect the service life of the seal. Improving the life of the seal is the key to improving the reliability of the boost valve.
For the specific application conditions of boost valve IV, common rubber seal materials include nitrile rubber (NBR), polyurethane (PU), fluororubber (FKM), etc. When selecting materials, it is necessary to comprehensively consider factors such as cost, performance, and environmental resistance.

technical data
| Material | Nitrile rubber (NBR) has excellent oil resistance and non-polar solvent resistance, as well as good mechanical properties and air tightness. |
| Hardness | 70 Shore A, indicating the hardness grade of the sealing ring. |
| Temperature range | The temperature resistance range of NBR materials is usually between -30°C and +100°C. |
| Media resistance | Suitable for aliphatic hydrocarbons, vegetable oils and animal oils, silicone oils, silicone greases, chemical fire extinguishing agents, diluted acid, alkali and salt solutions at low temperatures, and water below 100°C. However, it has poor resistance to aromatic solvents, halogenated hydrocarbons, ketones and ester solvents, and strong acids and alkalis. |
| Specifications | 56.87mm1.78mm (id). |
| Color | There are many colors for nitrile rubber O-rings, including black, brown, green, white, red, yellow, blue, orange, gray, etc., and colors can also be customized according to customer needs. |
| Product features | Nitrile rubber O-rings have good oil resistance, wear resistance, and relatively stable heat resistance. |
Certification
1. O-ring
O-ring is the most common type of circular cross-section sealing ring. It can be made of different materials, such as nitrile rubber (NBR), fluororubber (FKM), etc., and is suitable for various working conditions.
2. Gasket
A gasket is a flat seal that can be circular, rectangular, or special in shape. Common materials include rubber, polytetrafluoroethylene (PTFE), etc. It is used to seal the booster valve body, cover plate and other parts.
3. Spare ring
The spare ring is a ring-shaped seal with a preload. It has good sealing and flexibility and can be used for dynamic sealing or static sealing occasions.
4. U-shaped sealing ring
The U-shaped sealing ring is a seal with a special structure that can produce sealing effects in the axial and radial directions. It is used in dynamic sealing parts such as piston rods and pistons.
5. Square sealing ring
The square sealing ring is a sealing ring with a square cross-section, which has high sealing and pressure resistance. It is often used in static sealing parts such as the valve body and valve cover of the booster valve.
Rubber seal of boost valve IV
The size and tolerance standard of O-rings for hydraulic and pneumatic applications is GB/T 3452.1-2005, which specifies the cross-sectional diameter and allowable tolerance range of O-rings with different inner diameters.
