这plug of theFEP PFA衬里球阀必威体育娱乐betwayis a ball with an O-shaped hole. The ball rotates with the valve stem around the centerline of the valve body to open and close the lined ball valve. The inner wall of body and valve trims are lined with FEP,PFA and other fluorine materials.The special high temperature molding process is adopted to make the sealing surface compact,and the V-type PTFE packing makes the valve reach zero leakage.
这FEP PFA衬里阀专门设计用于对各种高度腐蚀性培养基管道的开放和关闭控制,并广泛用于石油,化学,染色,农药,酸和碱生产行业。它是当前抗腐蚀阀设备的理想选择之一。

1. FEP和PFA是白色和半透明的,适合所有腐蚀性培养基。力学,电气性能和化学稳定性基本上与F4相同,但是出色的优势是高动态韧性和出色的天气耐药性和辐射。必威体育娱乐betway对腐蚀具有更大的耐药性和对衰老的耐药性。
2.使用高温造型的氟过程,将FEP和PFA衬里氟材料放入特定的模具中,融化,然后被压机融化。衬里的球阀具有良好的密封性能和耐压性。必威体育娱乐betway
3.使用内衬里的氟过程,并从培养基中分离出衬里球阀内部的任何部分。必威体育娱乐betway阀杆和球是集成的。它们同时模制并用FEP或PFA衬里,以避免阀杆和球的变速箱间隙。
4. The structure of the FEP PFA lined ball valve is compact and reasonable, and the inner wall is very smooth. The valve body is produced by precision casting, with high strength and smooth appearance.It is quick to open and close and easy to operate. PTFE packing is used to achieve zero leakage of the valve.

1. The application temperature of the FEP lined ball valve should not exceed 150 °C. The material of FEP(F46) can be 150 °C for a short time, but for a long time working temperature should be controlled below 120 °C.Otherwise, the FEP material will be easy to soften and deform, resulting in valve leakage.
And the PFA lined ball valve can be used at 150 °C °C for long time and at 180 °C for short time.
2.不应有负压。衬里的球阀应防止管道必威体育娱乐betway中的负压。如果有负压,则易于形成阀内腔的荧光层层被吸收(凸起)并取下,导致球阀无法打开和关闭。必威体育娱乐betway
3.应在指定的使用范围内控制培养基的压力和压力差。如果压力不超出范围,则将燃料层破裂并变形,从而导致泄漏。
4.对于用于FEP PFA球阀的培养基,不应有硬颗粒,杂质和晶体,以免在球阀的必威体育娱乐betway开口和关闭过程中刮擦氟层。
5.禁止使用杠杆打开和关闭充满氟的球阀。必威体育娱乐betway打开和关闭后,不要强迫再次关闭以避免荧光塑料密封表面过早损坏。
选择各种类型的FEP PFA球必威体育娱乐betway阀,用户应尽可能理解并掌握操作条件,以便选择和使用正确的阀门以改善使用寿命。如果超出了运营条件的要求,则应向制造商提出,共同协商并采用相应的对策来解决。
