Features:
- Wafer
- Compact design with short face-to-face dimensions for minimum space requirements
- Dual shaft design allows interchangeability of shafts
- Torsion springs close the valve prior to flow reversal
- Torsion springs exert a lifting motion on the discs, enabling the center heel to open first, this prevents excessive wear of the seat in this area and provides a consistent wear pattern and long sealing capability
- Downstream stop shaft stabilizes the discs at high flow rates and prevents them from striking each other, which can cause premature wear, stress on the shaft and chattering
- Opens at 0.5 psi differential
Applications:
Designed for Liquids and Gases where Flow Reversal can Cause Surge and Water Hammer
Standards/Approval:
- ASTM A351 Grade CF8M Body
