Double eccentric butterfly valves can
achieve zero leakage easily and ensure sealing more reliable because of
the resilient seat design. Resilient seat design also can achieve low
torque so as to cost-effective of choosing actuator. Soft materials,
such as PTFE, have excellent applicability to acid or other media, thus
it’s use improves applicability of valves to various services.
