Application scenarios
Rapid Check Valve Closure Control in Multi-Manifold Systems
For check valves in multi-manifold systems, the external lever and spring improve the valve's closing response speed under rapid backflow conditions.
Pump Protection for Water Supply and Wastewater Lift Stations
For check valves in pumping lines at water supply pump stations and wastewater lift stations, the external lever and spring increase valve closing speed during rapid backflow caused by pump start-up and shutdown, supporting pump protection and backflow prevention control.
Backflow Control in Mining Transfer Pipelines
For check valves in liquid transfer pipelines used in mining operations, the external lever and spring increase valve closing speed when rapid backflow is anticipated.
Selection points
For NPS 2 to 12 in. Valves
This external lever and spring accessory is suitable for valve sizes from NPS 2 to 12 in. (50 mm to 300 mm) and should be selected in conjunction with compatible Bray check valve platforms.
External Lever and Spring for Faster Closing Response
Features an external lever and spring design to provide faster valve response and precise, reliable check valve closing control.
For Pump Protection and Multi-Header Systems
This accessory can be used in applications such as pump protection and multi-header systems where flow reversal occurs and rapid check valve closure is required.
Installation & maintenance notes
Verify Applicable Valve Size
Before installing the SA-01 external lever and spring accessory, confirm that the check valve size falls within the applicable range of NPS 2 to 12 in. (50 mm to 300 mm).
FAQ
How does the SA01 Series external lever and spring enable fast check valve response?
SA-01 provides a more direct actuation path through the combination of an external lever and spring, enabling faster valve closing response under controlled conditions.
What pipe diameters are covered by the SA01 Series size range?
The size range is NPS 2" to 12" (50mm to 300mm).
What are the key accessory types of SA-01?
The key accessory type is an external lever and spring, used to control check valve closing.
What industrial applications is this series suitable for?
It is suitable for applications including mining, multi-manifold systems, pump protection, wastewater lift pump stations, steel mills, and water supply pump stations.
What are the main factors to consider during selection?
The appropriate model should be confirmed based on the actual pipe size range, accessory type (external lever and spring), and specific application. The configuration must be confirmed according to the actual model and operating conditions.
