Class 150 lb API Flange butterfly valve
ANSI Class 150 LB API flanged butterfly valve meets ASME B16.5 and API standards. It features a compact, lightweight design, low pressure loss, and reliable bidirectional bubble-tight sealing. Available in soft seal and triple eccentric hard seal types, it supports manual, pneumatic and electric actuation for flexible industrial flow control.
Overview
Application: Suitable for medium-pressure industrial pipelines with frequent switching and stable flow regulation demands. Standard API flange connection ensures great universality and installation stability for fixed industrial piping systems.
