A large number of thermoplastic materials are offered in valves, mainly as soft-seat options for ball valve applications. Also lined valves like, lined butterlfy valve, lined globe valve, lined check valve. For this reason, the following section outlines some of the fundamental aspects of the properties, capabilities and application of these materials.
