About Plug Valve Seal Kits
Plug Valve Seal Kits are key components to ensure the normal operation of plug valves, helping to maintain the valve’s sealing performance, prevent leakage, and extend the service life of the valve by providing a complete sealing solution.
특별 기능
■ Custom Design: Plug Valve Seal Kits are typically designed to specific plug valve models and specifications to ensure seals and fittings are fully compatible with the valve. This means that the size, shape and material selection of each component in the seal kit are carefully considered to meet the special requirements of the latch valve.
■ Multiple Material Options: Because plug valves may be used in a variety of industrial applications and media, Plug Valve Seal Kits offer a variety of material options. This includes different types of elastomeric materials, PTFE, graphite, etc. to accommodate different sealing requirements and the chemical nature of the media.
■ Integrity and Reliability: Plug Valve Seal Kits typically contain all necessary seals and accessories to ensure plug valve integrity and reliability. This means that when using a seal kit for repair or replacement, all critical seals can be replaced at the same time to ensure effective sealing performance of the valve.
■ Complete kit supply: Plug Valve Seals Kit is usually supplied as a complete kit, including various seals and accessories required for the plug valve sealing system. Such kits provide a more convenient and efficient way to maintain and replace seals, avoiding the tedious process of purchasing and pairing seals individually.

Material Selection
The material selection of Plug Valve Seal Kits is crucial to ensure the valve’s sealing performance and adaptability to the specific working environment. Different materials have different chemical compatibility, temperature resistance and pressure resistance, so the appropriate sealing material must be selected based on the medium and operating conditions the valve will be exposed to. Here are some common sealing materials and their properties:
1. NBR (nitrile rubber)
- It has good oil resistance and fuel resistance and is suitable for media such as petroleum and fuel oil.
- Suitable temperature range is typically -30°C to 110°C.
2. FKM (fluorine rubber)
- Excellent chemical and oil resistance, suitable for corrosive chemicals in extreme environments.
- Suitable temperature range is typically -20°C to 250°C.
3. EPDM (ethylene propylene rubber)
- Excellent weather resistance, water resistance and vapor resistance, often used in water treatment and outdoor environments.
- Suitable temperature range is typically -40°C to 150°C.
4. PTFE (Polytetrafluoroethylene)
- Excellent chemical resistance and temperature resistance, suitable for strong acids, strong alkali and high temperature steam.
- Suitable temperature range is typically -200°C to 260°C.
5. HNBR (hydrogenated nitrile rubber)
- It has better heat resistance and chemical resistance than NBR, and is suitable for high temperature and high pressure environments.
- Suitable temperature range is typically -30°C to 150°C.
6. Viton (fluorosilicone rubber)
- Excellent heat resistance, chemical resistance and oil resistance, suitable for corrosive environments with high temperature and pressure.
- Suitable temperature range is typically -40°C to 300°C.
7. Silicone (silicone rubber)
- Excellent heat resistance and weather resistance, suitable for high temperature environments and outdoor use.
- Suitable temperature range is typically -60°C to 200°C.
8.PTFE Filled
- Filling materials such as glass fiber or carbon fiber can enhance the mechanical properties of PTFE and improve its wear resistance and pressure resistance.
- Suitable for wider temperature and pressure ranges.
