Tilting Disc Check Valve with Hydraulic Damper – Class 150
ASME B16.34 tilting-disc check valve fitted with a counter-weight lever and a hydraulic damper cylinder. The damper controls the closing stroke to limit flow reversal and water hammer in pump discharge lines, and needs no external power.
- Pressure
- Class 150
- Size Range
- 2" to 24"
