High Performance butterfly valve

Product:High Performance butterfly valve

The triple eccentric butterfly valve, which makes use of a metal seat, is therefore able to withstand a greater amount of pressure, compared to resilient seated butterfly valve. The seal of the eccentric disc could be either metal/Graphite multi-layer design, or fully metal-to-metal design. The multi-layer design could achieve zero leakage and simple maintenance, while the metal-to-metal design is more reliable in higher temperature and pressure. Basically speaking, triple eccentric butterfly valve is both applied in shutoff or throttling service.
