Application scenarios
Check Valve Protection for Pulsating-Flow Pipelines in Wastewater Treatment
Provides external speed control for NPS 12 to 54 inch check valves in wastewater treatment systems. Adjustable hydraulic and pneumatic speed control slows valve opening and protects the valve disc assembly during the final stage of travel, making it suitable for pulsating-flow conditions.
Check Valve Speed Control for Industrial Waste Treatment Piping
Provides external hydraulic and pneumatic speed control for pipeline check valves in industrial waste treatment facilities, allowing adjustment of valve opening speed and protection of the valve disc assembly during the final stage of travel.
Check Valve Protection for Supporting Piping in Solid Waste Treatment
Provides external control for large-diameter check valves in supporting pipelines at solid waste treatment facilities. Adjustable speed control slows valve opening and protects the valve disc assembly during the final stage of travel under pulsating-flow conditions.
Selection points
Adjustable Hydraulic and Pneumatic Opening Speed Control
SA-50 is a hydraulic and pneumatic speed control accessory that adjusts valve opening speed for more controlled valve operation and flow management.
Valve Disc Assembly Protection During Final Opening Stage
This controller slows valve opening to protect the valve disc assembly during the final degrees of the opening stroke.
Suitable for Pulsating Flow and Related Processing Applications
SA-50 is an ideal device for pulsating flow applications. Listed applications include industrial waste, wastewater treatment, and solid waste treatment.
SA-40 Compression Spring Configuration
SA-50 uses an SA-40 compression spring and should be distinguished from the H-100 model, which uses an SA-01 compression spring.
Compatible with NPS 12 to 54 in. Size Range
The specified size range for SA-50 is NPS 12 in. to 54 in., equivalent to 300 mm to 1350 mm.
Installation & maintenance notes
Valve Final Opening Speed Adjustment
When installing and commissioning SA-50, use its adjustable speed control function to slow movement during the final degrees of valve opening and protect the valve disc assembly.
Verify SA-40 Compression Spring Configuration
SA-50 should use an SA-40 compression spring and be distinguished from the H-100 model using an SA-01 compression spring to avoid mixing spring models.
FAQ
How does the SA50 Series operate, and how does it decelerate to protect the valve disc?
The SA50 Series uses adjustable hydraulic and pneumatic speed control devices to slow movement during the final stage of valve opening, protecting the valve disc assembly and enabling more precise flow management.
What pipe diameters are covered by the SA50 Series size range?
The applicable size range is NPS 12 to 54 inches (300mm to 1350mm).
What working-medium control types are available for the SA50 Series?
The device provides two control methods: hydraulic and pneumatic speed control.
What is the relationship between the SA50 Series and pulsating-flow applications?
With adjustable speed control, the SA50 Series is an ideal choice for pulsating-flow applications, providing smooth control at the end of the opening stroke.
What should be considered regarding spring combinations for the SA50 Series?
The SA50 Series uses SA-40 compression springs; for other types, refer to the relevant model documentation to confirm compatible spring combinations.
