PTFE弹簧蓄能密封圈-Spring Energized Teflon PTFE Seals
Spring Energized Teflon PTFE Seals Energized PTFE seals offer extreme temperature, high pressure, chemically inert static and dynamic sealing for the most demanding applications. Our thin flexible PTFE sealing jacket, resilient by design, utilizes a spring designed to apply outward pressure to the sealing element at low pressures. A highly efficient seal is created as the system pressure increases enough to take over from the spring and engage the shaft or bore. The spring or energized seal assembly provides permanent resilience to the seal jacket and compensates for jacket wear, hardware misalignment and eccentricity. The jacket material is critical in design to assure proper seal performance. We offer PTFE compounds specific to the application i.e. High PV seals, cryogenic seals, high temperature seals, and PTFE seal alloys with fillers such as PTFE Graphite, PTFE Polymide, PTFE Carbon, PPS PTFE, and Rulon L, Rulon J and Rulon AR equivalents.
