FAQ

How do SA40 Series check valve accessories work?

The SA40 Series increases closing force through an external compression spring, enabling the valve to close faster when media flow stops and reducing surge and backflow.

What pipe size range can the SA40 Series cover during selection?

The size range is NPS 2" to 48" (50 mm to 1200 mm), covering applications from small and medium to larger pipe diameters.

What optional installation/actuation components are available for the SA40 Series?

Accessory types include external levers and compression springs, used to improve rapid-closing performance and facilitate on-site adjustment.

What typical applications is the SA40 Series suitable for?

It can be used for rapid closing, header systems, mining, pump protection, wastewater lift stations, steel mills, and water supply pumping stations.

How can the specific configuration be confirmed during actual selection?

The specific configuration must be confirmed based on the actual model and application conditions. During selection, confirm it in conjunction with information such as the medium, pressure rating, and pipe diameter.
