Product Details
Design Features:
Yaosheng-double door check valve is suitable for automatically preventing
backflow in systems that need to allow flow in one direction and prevent flow
in the opposite direction. The double door check valve is recommended for
cleaning liquids and gases. Due to its cost-effective design and non-impact
performance, it has a reputation for excellent performance in refineries,
petrochemicals, gas liquefaction, other process industries, and HVAC
applications. Lighter weight and shorter laying length save initial cost,
require less space, and are easier to install than full-body, swing type.
