Medium Points
Swing type is more suitable for horizontal pipelines, butterfly type is suitable for occasions where space is limited
Lift type is suitable for high flow rate, double-plate type is suitable for large-diameter pipeline.
Corrosive media.
Ball type is suitable for small diameter, swing type is suitable for large diameter pipeline
Other considerations
Adaptation of fluid characteristics: according to the medium corrosivity, temperature, viscosity selection check valve type (such as swing type, lifting type, ball type).
Installation direction: ensure that the valve installation direction and media flow direction, to avoid reverse installation failure.
Standards: follow ASME, API and other industry standards to ensure design compliance
