YDF double offset 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.
