Non-Slam Disc Check Valve

Disc Check Valve (Wafer Type) Manufacturer: FlowBiz Exports

The FlowBiz Disc Check Valve is a spring-loaded, unidirectional valve that fits between two pipeline flanges. Its "wafer" design makes it significantly lighter and shorter than traditional swing check valves, reducing both the initial cost and the structural support required for the pipeline.

The disc is held against the seat by a spring; as the upstream pressure exceeds the spring force, the disc moves away from the seat to allow flow. When the flow stops or reverses, the spring assists in a quick, silent closure to prevent water hammer.

Key Features & Advantages

  • Compact & Lightweight: The wafer design minimizes the "Face-to-Face" dimension, making it ideal for skid-mounted systems and tight engine rooms.
  • Spring-Assisted Closure: Ensures the valve closes quickly before flow reversal can gain momentum, effectively mitigating hydraulic shock (water hammer).
  • Low Pressure Drop: The streamlined disc design allows for high flow capacity ($C_v$) with minimal energy loss.
  • Universal Mounting: Unlike gravity-style swing check valves, the spring-loaded disc allows for installation in any orientation—horizontal, vertical-up, or vertical-down.
  • Diverse Material Options: Available in various grades of Stainless Steel and Carbon Steel to withstand corrosive chemical and steam services.
