Ball Valve Seat and Seal Rings
The most common fluoropolymer application is used as sealing material for Valves. We provide valve seats,seat inserts, thrust washers and backup rings, stem packings by wide range of materials, such as PTFE, filled PTFE, TFM , PCTFE, PEEK，Vespel®, PCTFE, PI, Nylon and Acetal.
Over the years, based on our own advantages in the field of high performance polymer materials, We've been working with valve customers all over the world to manufacture various soft seals & seats.
| 材料の選択 | 主なプロパティ | 温度範囲 |
| バージンPTFE | 摩擦係数が非常に低く、耐薬品性に優れています。 | -40 ℃～ 260 ℃ |
| 15% and 25% Glass Filled PTFE | Decreased compressive strength and lower deformation under load than virgin PTFE. Better wear resistance, higher compressive strength and lower deformation under load. | -40 ℃～ 260 ℃ |
| 5%,15% and 25% Carbon Filled PTFE | Improved mechanical strength compared with virgin PTFE. Excellent wear properties, retains excellent frictional properties, good choice for seals and rings in dynamic and high-pressure applications | -40 ℃～ 260 ℃ |
| 5% MoS2 Filled PTFE | PTFE の硬度と耐摩耗性が向上しました。滑り性が向上し、摩擦が減少します。 | -40 ℃～ 260 ℃ |
| ステンレススチール入りPTFE | 極めて耐久性に優れています。極度の負荷や高温下でも優れた強度と安定性を発揮します。 | -40 ℃～ 260 ℃ |
| TFM Series | バージンPTFEよりもはるかに高密度なポリマー構造。優れた応力回復力を発揮します。 | -80 ℃～ 260 ℃ |
| PCTFE | Ideal sealing material for lower temperature and high pressure, good mechanical properties. Excellent for LNG, Cryogenic and Oxygen use. | -240 ℃～ 120 ℃ |
| asfasdf | 高温下でも優れた耐薬品性と機械特性を持ちます。 | -40 ℃～ 260 ℃ |
| カーボン充填PEEK | Virgin PEEKと多くの類似特性を有します。特に高温および高負荷環境に適しています。 | -40 ℃～ 260 ℃ |
| PFA | Excellent chemical and temperature resistance, electrical insulation properties | -100℃〜+ 260℃ |
| UHMWPE | 酸化酸と有機溶剤を除き、腐食性化学物質に対して高い耐性があります。 | -60℃〜+ 80℃ |
| アセタールとデルリン | Good resistance to wear and deformation under load. | 80°Cまで |
| PI（ポリイミド） | Significantly higher modulus, excellent wear and friction properties, good thermal-oxidative stability and high mechanical strength | 320°Cまで |
| Customized Material by HONGDA | Designed & produced as per specific applications | / |
