Choosing Between PTFE and Rubber Seats for Butterfly Valves: A Material Science Perspective
By Tianjin Worlds Valve Co., Ltd. on 07/05/2025
This article compares PTFE and rubber butterfly valve seats across eight critical factors: chemical resistance (PTFE excels in harsh media), temperature tolerance (-200°C to 260°C vs. -50°C to 120°C), mechanical durability (PTFE maintains rigidity), environmental impact (rubber degrades faster), installation complexity, lifecycle costs (PTFE's longevity offsets higher initial cost), industry-specific compliance (FDA/chemical vs. water standards), and application suitability (chemical vs. municipal systems). Material selection balances operational demands and sustainability goals.
