Flanged Ends Ball Type Check Valve
**BALL CHECK VALVE ANSI 125**
**DESCRIPTION**
This ball check valve is designed for silent closing, preventing water hammer effects. It features a full bore flow design, offering large flow capacity with minimal resistance. Compared to swing check valves, it reduces the loss of water head by up to 50%. The valve can be installed horizontally or vertically. It operates within a temperature range of -10°C to +80°C and is suitable for water, sewage, heavy, and viscous liquids.
**TECHNICAL SPECIFICATION**
- Threaded ends: DN25 to DN80
- Flanged ends: DN40 to DN400
- Thread type: BSP or BSPT
- Flange type: EN 1092-2 PN10/16, Table D and E
- Max working pressure: 16 bars
- Operating temperature: 10°C to 80°C
- Minimum backpressure for tightness: 0.3 to 0.5 bar
- Face-to-face dimensions for flanged types: EN-558-1 series 48 (DIN3202 F6)
**APPLICATIONS**
Ideal for pumping stations handling clean water, sewage, and loaded or viscous fluids.
**TECHNICAL PERFORMANCE**
- Full bore design ensures unobstructed flow
- Self-cleaning ball mechanism
- Low pressure drop and quiet operation
- Removable bonnet allows for easy cleaning or ball replacement without removing the valve from the pipeline
- Suitable for both horizontal and vertical installation
**TESTING**
- Seat test: 1.1 times normal pressure
- Body test: 1.5 times normal pressure
