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.
| Интихоби моддӣ | Хусусиятҳои асосӣ | Диапазони ҳарорат |
| Вирҷинияи PTFE | Коэффисиенти хеле пасти соиш ва муқовимати аълои химиявӣ. | - 40 ° C ба 260 ° C |
| 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 ° C ба 260 ° C |
| 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 ° C ба 260 ° C |
| 5% MoS2 Filled PTFE | Афзоиши хосиятҳои PTFE аз сахтӣ ва муқовимат ба фарсудашавии. Афзоиши хосиятҳои лағжиш ва кам кардани соиш. | - 40 ° C ба 260 ° C |
| Stainless Steel Filled PTFE | Extremely hard wearing. Excellent strength and stability under extreme loads and elevated temperatures. | - 40 ° C ба 260 ° C |
| TFM Series | Much denser polymer structure than Virgin PTFE. Displays better stress recovery. | - 80 ° C ба 260 ° C |
| PCTFE | Ideal sealing material for lower temperature and high pressure, good mechanical properties. Excellent for LNG, Cryogenic and Oxygen use. | - 240 ° C ба 120 ° C |
| ПЕШ | Excellent chemical resistance and mechanical properties at elevated temperatures. | - 40 ° C ба 260 ° C |
| PEEK бо карбон пур карда шудааст | Many similar properties to Virgin PEEK. Particularly suitable for elevated temperatures and high load situations. | - 40 ° C ба 260 ° C |
| ПФА | Excellent chemical and temperature resistance, electrical insulation properties | -100 ° C то + 260 ° C |
| UHMWPE | Highly resistant to corrosive chemicals, with the exception of oxidising acids and organic solvents. | -60 ° C то + 80 ° C |
| Ацетал ва Делрин | Good resistance to wear and deformation under load. | то 80°С |
| PI (полиимид) | Significantly higher modulus, excellent wear and friction properties, good thermal-oxidative stability and high mechanical strength | то 320°С |
| Customized Material by HONGDA | Designed & produced as per specific applications | / |
